0:03 👉🏻 Impossible Nail: Not impossible, but creating this does depend on the use of some amazing physical properties of wood. I won’t reveal the method here but a quick search on KZhead produces a few how-to videos showing the process. The nice version of this puzzle featured here is from @emvz.creations
(mechanics, physics, engineering, STEM, puzzle, science)
0:36 👉🏻 Impossible Bolt: Not impossible- but carefully engineered and machined. This puzzling curiosity was inverted by Scott Eliott and machined in solid brass by puzzle crafters Steve Nicholls and Ali Morris of TwoBrassMonkeys.
1:57 👉🏻 Impossible Jar with Golf Ball: The puzzle aspect is to consider how this object was produced. This incredible piece was made by craftsman and artist Nathan Nickerson, and comes with the golf tee display stand (a nice touch!)
2:27 👉🏻 Impossible Bottle Sculpture Puzzle: The puzzle aspect is to consider how the bottle was produced (I personally have some theories- but I do not know the secrets of this artist). I can tell you with high certainty that the bottle was never cut or altered in anyway, and it was not somehow formed around the objects. This bottle by Phil Evans is one of the best I’ve seen.
3:10 👉🏻 Forks and Toothpick Balance: Incredible DIY physics toy.
(bartrick, balance, centerofmass, equilibrium, physicstoy, stability, fork)
3:38 👉🏻 Impossible Dovetail
(impossiblebox, dovetail, dovetailjoint, impossibleobject)
4:22 👉🏻 Four Marble Puzzle: one of my favorite physics brain teasers- A beautiful and well-made puzzle from Creative Crafthouse.
(brainteaser, marbles, centripetal, centrifugal, rotation, kineticenergy)
4:45 👉🏻 Impossible Arrow: Not impossible, but creating this does depend on the use of some obscure physical properties of wood (similar to the impossible nail). This delightful design was made by illusionist and artist Victoria Skye @vicskye
5:20 👉🏻 Impossible Wallet
6:08 👉🏻 Impossible Knot: how did this overhand knot get into this closed continuous band of rubber? It did not get there by cutting the loop, tying a knot, and rejoining it. Amazingly this band was once a rubber o-ring. How was it cut to produce a knot? An “impossible object” related to the Möbius strip by mathematician and artist George Hart- a brain teaser puzzle he calls “Tying the Knot”.
6:46 👉🏻 Raketti Puzzle
BONUS CLIP
Nova Plexus Puzzle: 12 identical brass rods can create 4 interlocking triangles in a perfect symmetry- look carefully and you can see that each rod is in an identical configuration with the 5 others that connect with it. Precision machined notches on the ends of the rods allow them to interlock with elastic tension such that vector sum of the 5 forces on each rod is zero- creating this astonishing geometry as the equilibrium state. Unlock the ends of any two rods and the system instantly disassembles. Invented and designed by artist and computer scientist Geoff Wyvill in 1978, this puzzle has just recently been made available for sale with a limited production run.

I don't know
The Impossible Bolt uses 2 Spitals, one large for the Bolt with large Spiral and one unvisual little one to the other direction wich can only geht taken by the Bolt with little Spiral
Ok.. I tried💪 1 it may grown like that or it may made carefully.🤔 2 Those two bolts has different. threads which makes them to move like that. 3 by slightly heating the jar we can also do that. 4 may be the bottle has a cut at other side or it may manifactured like that. 5 it's because of center of gravity. 6 it can be opened by taping hardly on the top and then moving the top part to one corner. 7 we can move them by rotating or spinning the toy on floor 8 the three may grown like that! 😂 9 there is answer it self in question it's all because of Jacob's ladder trick 10 hmm....I don't know.😉 11 by blowing air with straw!!! So I did. can you please post my name in your video plz. It's an humble request from your subscriber and your fan.....! Plz mention my name in your next video.. plz
And plz reply for my comment..
For 1 experiment you just boiled the wood and compres the one end and fix the nail that too easy
Arrow and nut puzzle: insert the nut into the branch and wait for the plant to grow until the branch becomes thick enough to make the arrow.
Arrow is made of 2 separate parts that slide into one another
Hai sir, I'm from India
It says nothing was cut or glued. If the arrow put in a steamer for a while, it may be able to be squeezed enough to fit through. That's how they get the nail in the board, they put it in a steamer, and it will bend enough to get the nail in.
When the plant is still small we insert the nut into the branch and wait until it grows bigger then cut it out to make the arrow.
@@yendavarunkumar6824 भारत कहो।।
This is the most unsetteling video i watched to start my morning.
Does KZhead recommend this thing in morning only
How the hell is this video unsettling?
😂
4:43 Spin it really fast at the centre
The impossible bolt is rather simple, two types of threads, fine and course. The fine threads are cut onto the surface of the course threads, just counter clockwise. One nut is threaded to use the fine threads and the other is threaded to use the course threads. I can program a CNC lathe to make these.
nice catch.
Machinists and engineers ruin all the fun.
I can cut that on a manual lathe before you are finished programming that silly CNC.
@@reggienone966 True, if you only want 1.
well plausable but i not see fine thread on bolt chest. so fine thread minor is just exact match major of course thread. it mean if you just push without roll it go in too and yes G76 xD or G32
The most mind teasing channel, lol.. I love it.
god damn it, you better upload the solution:)
the forks and toothpick balancing is possibly about the 'centre of mass' being lower than the contact point giving it stability with gravity. Was either carefully placed or the inside of the toothpick was set alight and stopped burning on contact with the glass.
Wood is amazingly compressible in the cross-grain direction when steamed or soaked in hot water. A lot of "impossible" woodworking uses this fact.
7:19 it is because metals have faster rate of heat transfer than non metals. If you touch a metal and a piece of wood at room temperature, the metals feels cooler right? If you check it using an Infrared thermometer you'd find they're at the same temperature. What we humans feel is the rate of trnasfer if heat. When we touch the metal heat from our hand starts to flow towards the metal to achieve equilibrium and thus it feels cooler.
The lock and deck of cards in the bottle really has me stumped. All I can think of is that the bottom of the bottle was cut and melted back in place?
Looks to me like the bottle was joined halfway up, there's a slight imperfection in the sides
1. The wood was heated and cramped at one of the outer notches, the hole was made at that point and the nail inserted to the hole, then the wood was heated again until it perfected it's original state ✌
Geez how u so smart
The forks and toothpick trick is based on centre of mass concept I think
Centre of Gravity.. Hare Krsna🌹🌹
@@adityaranjanbal centER of gravity
A few minutes ago I saw this video in the recommendations. It's a marvelous channel. I subscribed it instantly. I would love learning through it.
The bolt and the fine thread nut are both left handed threaded. Also the thread pitch of the fine threaded nut looks to be 3 times that of the bolt. The inside diameter of the nut is only slightly smaller than the outside diameter of the bolt so that 3 threads of the nut sit perfectly inside each single thread of the bolt and goes on and off in the normal but left hand way. The coarsely threaded nut is threaded right handed. Its inside diameter is essentially the same as the bolts outside diameter so the nut goes on and off simply because of friction. For the golf ball in jar, just press the gulf ball into the jar.
Very interesting these gives insight in the thinking that every impossible work may b possible
Thanks that you are giving us knowledge about thing that not know👍👍
4 - cut the wrap on the bottom, push all the cards one by one to the bottle, open the box from both sides, bend it, push it to the bottle. The lock chackle may be removable in open state.
The first one is made by placing one end of the wood in boiling water till it softens. Then you compress the wood so you can drive the nail in after which you place back in boiling water so the wood can reform. Let it dry, job done
Yeah that's what I think
4:13 Impossible Dovetail solution is that the parts move diagonally to solve the puzzle. 4:35 solution is the centripetal force. To get the four balls on the corner, we need to spin it and the balls will go to the edges. 5:58 The ribbon changes its place whenever u change the sides.
Great answers. But the force is centrifugal not petal.
@@AbhishekGaurVioletVenom yeah, i thought i was writing it wrong. Btw thnx for correction
@@SoulEaterGT You weren't completely wrong ... a body requires a centripetal force, and therefore an acceleration towards the centre, to enable it to travel in a circle (i.e. stay in its original position when the block is spun). Because there is no such centripetal force it tries to move in a straight line but is constrained by the channel in which it sits, so moves to the outside. There is no actual "centrifugal force", just the absence of a centripetal force!
@@salokin1 Thank you. Engineers/Physicists are FOREVER explaining this, "centrifugal force" is really a fictitious force, with the opposite sense to the REAL one...so why all those so called centrifugal pumps, etc.? WHO is the engineer/inventor/whatever that was asleep at the wheel, nomenclature wise? Or was it all in the translation? :-P Now what about the "force" of gravity. Obviously gravity can generate measured forces between masses, but is it ITSELF really a force, or just some space time gobbledygook, as that squirrelly haired fellow once posited? And, as they say, "What about Naomi?"
It’s not just diagonal sliding. You first have to bang the marble away from the magnet on the brown side then slide diagonally.
I think aluminum is a better melter bc it transfers heat/cold much more quickly than wood does.
The table is heated?
You're right aluminium is a good heat conductor while wood is not.
@@megangilbert9043 no, it's exactly what diane greene said. Metal always "feels" colder than wood, even though it's the same temperature. That's because the temperature is USUALLY lower than your own body, and thus heat transfer takes place. This is how you feel temperature, which this test shows you isn't the most accurate. The wood feels less cool than the metal because it transfers heat very slowly. This means it acts like an insulator and keeps the ice cold for longer, wheras the metal pushes all the heat it has into the ice very fast because it conducts heat very well.
The arrow and the bolt. The arrow was soaked in water for a while making the wood soft. It was then forced through the center of the bolt. Lastly the wood is allowed to dry back up.
You can do The same with The first one, The nail in the wood pice
@@draupnerbattlepirates7238 Yes, but my proposition is to take better a hot water :)
have use boiling water
The Raketti Puzzle: Slowly pour water into the bottom until it floats high enough to grab it.
no you just have to blow its top
I don’t think it’s the intended solution, but just push on the coned top to knock it over and then just pull it out.
1st puzzle, the wood is soaked in hot water then both end pieces are squeezed with a vice allowing the nail to be hammered thru the centre lugs!
nope .
Only one end needs to be compressed, as you only drive the nail from one side. But, yes.....you hit the nail on the head 😅
I think one would have then been able to see at least some signs of that then, but the wood is totally smooth with no indication of any tampering. My take on this is that the nail just looks solid, but actually are in three pieces.
@@chrisbresler5444 KZhead it. It is literally how it's done.
@@chrisbresler5444 kzhead.info/sun/a7h8p7SqmH-Eeps/bejne.html
2: threads on one nut are clockwise and other are anticlockwise. 7: Spin it
1. the wood must be boiled first, to make its flexible 2. The grip of nut is not same, 1 going up, another going down, if u can understand me
Shi ja rhe ho motabhai
Its not enough for the threads on the nut to be different. There has to be two different threads on the bolt as well. They do this by making one much bigger than the other so you cant see the fine thread.
The coarse threads have fine threads cut into the peaks.
On the first one is the hole is drilled before the nail is inserted, if its hammered in, the wood might split. This makes it more mysterious since the nail can slide proving it is one piece.
So. Good and magical. Vidéo continue like it 😉 please
These are so fun! 👏🏼
Glad you like them!
Well all the work is of illusions and extraordinary carpenter.
1. wood was soaked, squeezed in a vise, then nail put in. Left to dry, the wood returns to its former size. 2. One nut has left, the other has right-hand threads. 3. Jar heated with hot water, then dumped out, golf ball placed on top sucked into it by steam cooling off. 4. Bottle built around the contents. 5. forks are balanced like tensegrity. 6. Dovetail joints really slide off. not how it looks. 7. spin it on the table. 8. same technique as #1 9. straps are folded under the bill when wallet is flipped. Straps NOT anchored in the center fold. 10. not enough detail is visible on my phone. Guessing, the strap is really an O-ring. 11. Wood is an insulator, aluminum is not.
4. Bottle built around the contents.? How does one do that without burning said contents?
1. Already knew it. 2. Figured that one out. 3. Didn't know this one. 4. If that's how they did it. I call foul. 5. Knew this one already. 6.Figured this one out. 7. Knew it. 8. Knew it. 9. Have no idea what a "Mobius Strip" is. Never heard of it. 10. For this one I was thinking to poor water into the bottom part and then the wood cone topped cylinder will float up and you can just grab it and take it out.
For the REALLY interesting one, the two way nut: That fine thread shown in the hint might be a high pitched multiple thread, similar to what some gallon milk jugs use(d?), allows you to make a very high pitched thread that still maintains strength, which in this application is probably necessary, or at least helpful, since there is almost no thread contact area in the overriding fine thread. The fine thread pitch would obviously be 2X the bolt pitch, opposite "handed". The opposing fine thread is just cut marginally into the course bolt thread, so you can't resolve it in the vid. Very clever. See, I think I FINALLY got there...hoping anyway...seems a pretty sure bet. If you hadn't shown the hint, that one would have been REALLY difficult. It occurred to me that you could just tap one right and one left thread of the same diameter and pitch and this would still work (with care engaging), but then it would be obvious to even the casual observer. The "impossible" dovetail one is not made very well..you can see two of the dovetails are off center and two are not, and the locations of the non-centered slides give it a way a bit. Needs more care in design/construction to really pull it off well. I already know the "trick" to the "nail in dovetail"/castellation types, so no reason to give it/them away. And there are multiple methods and "mixtures" to accomplish the movement for the necessary clearances, not just the obvious one most commenters will likely pick (used to use them building balsa hand launch gliders, and the even greater propped ROG versions). The real problem with any of those methods is that the wood is never the same afterward, structurally. The softened fibers do not return to normal strength later.
You can see the left-handed threads cut into the peaks of the largeer right-hand thread. look closely at the light reflecting from the thread. In some position the ridge looks doubled.
@@flintsmith4771 That would totally support my entire analysis...only given the thread sizes, I expect it is more than doubled, even. The other thing I noticed was the larger diameter thread peak hold on the fine threaded nut. Thx for corroborating visually.
Pound a nail into a tree, wait a few years until the tree grows more and embeds the nail, then carve the whole thing out carefully, using something like a magnetic stud detector to see where the nail is. Or maybe melt the steel and pour it into a heat-resistant mold that is embedded in the wood, let it harden, and remove visible pieces of the mold (if you managed not to set the wood on fire).
soak the wood, compress one end in a clamp, hammer the nail in and then re-soak and the wood expands back to its original state.
#1: Cut the wood, then soak it in water and clamp the end so the nail can be inserted. #2: The thread depth on the nuts is different so one travels clockwise and the other counter-clockwise. #3: Perhaps under high pressure the golf ball could be made small enough to go into the jar... #4: I'm not sure on this one... possibly the glass blown "around" the items? #5: Old trick... the balance is maintained because of the handle of the forks. #6: Cute.. nice use of dovetails. #7: Spin the cube. #8: Was the arrow put through the nut, or was the nut put on a branch and allowed to grow? #9: I want one. :D
Wonder filled secrets hidden inside the crafts! The brainworks of human being! Pranamam to the inventors
#1 the wood is soaked so it becomes flexible. The nail is put in after it is bent and then it is returned to its original shape and dried.
Correct! You can tell by how he moves it that it is a very lightweight wood, like Balsa.
The nail was cut in 3 pieces, it doesn’t actually go through the whole wood
@@yvancg Nope - no cutting
Soaked and heated - that's the way to bend wood when you make those beautiful bent-wood pieces of furniture.
Soked in what? Water? Jizz? Ffs what the hell are you guys talking about? Is it the liquid that shall not be named? Just my way of asking sry for being aggresive
First time I saw your channel video it's mind blowing and eagerly waiting for answers bcas I can't able to crack it
4:43 - to get them all rolling out at the same time, you spin the “toy” on the table and then they will all roll out.
You are intelligent!
3:12 --> in this challlenge it's classic! It's just using the center of mass that the structure has (forks and toothpick)
The real mystery is why the fire goes out. Otherwise, any part of the toothpick extended past the balance point is unnecessary.
Love this. Better then TIK TOK. Keeps the brain working.
Science is a beautiful gift to humanity. Science is magic that works.
3: Jar was heated and streched, they put the ball in, heated the jar again and shrunk it. Glass is elastic when heated and you can change the shape of it. You can do it multiple times, 4: They cut the bottle in half, put the stuff in, then they heated the glass to stick the 2 pieces back together. 5: Simple thing there. It is all about center of gravity. The place where toothpick touches glass is right at the center of mass of the whole fork contraption. 6: Turn the thing brown side down (to prevent bearing ball from locking it) and then slide it open. 7: Put the thing on the turntable and use centrifugal force. 11: Maybe hit the table with you'r fist hard enough for it to jump out? Use glue to remove it? Use vaccum?
this is amazing. will study how it's done
no.8 This gadget uses a wood-enhanced hardness processing technology that is already energy-produced. It continues to press the wood with a mold in a dry environment of 100C. The limit is 24 hours to reduce the thickness of the wood to 1/5 of the original. Here, first make an I-shaped wooden stick with a thin middle and two thick ends, and use a mold to press the big end into the nut in a high temperature environment. Then put it in boiling water and cook it until it returns to its original size. After drying, carve the two ends into an arrow shape.
👍🏼
👍🏼
Clearly states the arrow was carved before the nut was placed on it. You could have just said "wood in boiling water and compress. Fit nut over. Dry the wood."
Number 7..if you spin the box centrifugal force should make the ball bearings move to the outside edge. 🤔
Yes! you got it right
Channel popped up. Super cool and smart. Nice bro. Nice. I’m a fan indubitably. Had to use a big word for you Lol. Keep up the good work. I subscribed
I have done it without seeing hind and ofcourse the comments. 1. The nail is carved from the wood....the nail was inside the wood ( maybe it kept with the seed) 2. Their are two bolt...one bolt is clockwise and the second bolt is fixed on 1st bolt ( maybe by glue or something else) which is counterclockwise 3. The golf ball was put on the top of the jar first, secondly it air was passed from the between of ball and the jar and it went inside 4. The deck of cards are placed on the bottle one by one by folding the cards...it is done very finishely...and then the padlock kept inside bottle tied with the cork Or The bottle was cut from bottom and the deck of cards were glued and the padlock were tied on the cork ( it was open when it went inside the bottle then locked and tied to cork very finishely) 5. It's an center of mass ( c.o.m) concept ...the net c.o.m were on the side of glass so it is balanced 6. The good thing about the object is that how the red thing were fixed inside the wood.
3:43 lo conozco perfectamente, Cuby lo mostró en su canal
@@yosoy3936 en realidad si la mostró, pero en instagram, ahí encontrarás la verdad
One of my friend told me about this channel i was interest in this kind of things so i just sub your channel
Maybe the golf ball and jar were in a tank under high pressure- the ball was squeezed down until it dropped into the jar.
Puzzle #1 Only wood worker knows
2:06 !!👍On putting golf ball in liquid nitrogen,it will shrink and we can insert it in that vessel
Really?
OK, but would it help, or hurt, if you heated the vessel? I know the answer, but do you, , if you don't already, without looking it up?
@@rendrennan2294 Like the hard-boiled egg into the bottle trick. I can't believe I didn't think of that!
It's done the same way you seal canning jars. Boil the glass, and the ball, leave the jar about half full of boiling water, quickly put the ball on top and push it in a little, when the water cools, it creates a vacuum, sucking the ball inside, then dump out the water and let it dry.
#2. If you pause the video, you will notice that the bolt has 2 sets of threads cut into it - one for left hand screws and one for right hand screws. One nut has left hand threads cut into it and the other has right hand threads cut into it.
No it's not like that The difference is in the bolt threads
@@kaushik3528 Isn't that what I said? The bolt has 2 different sets of threads.
Excelente, muy bueno. Excelent, very good.
11. Add hot water to. Heat expands the metallic lower piece allowing the water in so the wood floats
Impossible dovetail was a trick by my woodworking teacher.. it slides diagonally into each other instead of orthogonally
You had a good woodworking teacher
the nail and arrow wooden puzzles are easy after seeing similar things on the wood wright shop. takes steam and clamping the wood until its compressed enough to do the trickery then re steam for the wood to expand back out to normal size again.
He said wood hasn't cut or glued but nail may b in two parts
@@DontWorryg one of the "fingers" is steamed and compressed until the nail can pass it then resteamed to expand it again. I saw it done on the wood wright shop
Great video, great job! Thanks for sharing!
First One: Make the wood block with slots out of it. Soak one of the ends in water. Clamp the soaked end tightly in a vice, compressing it. Hammer the nail in. Put the compressed end back in water. Done.
This show helps me to sleep well......😪😪
Ra arri puka ala nidra vasthundhi ra antha confused ga vuntae avi. Nee yamma lanjakodaka
The only way you could get the nail in the wood I can think of is steaming the wood to bend it.
You're close.. you place one end of the cut wood in boiling water for about 20-30 minutes, place that end in a vice and smash that end. Then you drill through the center pieces, insert the nail and return it to the boiling water for another 20-30 minutes. The wood becomes compressible when boiled and expands from being compressed when you return it to the boiling water. The same basic principle used to bend wood. Bending is done with steam but the thickness of this would take a very long time to steam it to be able to smash it enough to compress it enough. I didn't figure it out, I saw it on a KZhead channel. I know how some of the other ones work too. Just too long to explain in writing. The square with the X and you have to get the 4 balls out at the same time, simply spin it, centripetal force does the trick.. Good luck with the rest.
Simply fascinating. Thank you.
6: awesome when you opened it
The forks: Gravity tension simply.
Center of maas bro😎😎😎
No. It's center of mass.
4:32 !👍on rotating ,all 4 marbles will move to the end
Well I think there's an easier method. They mentioned that the centre is kept at slight lower level than the edges so that the marbles tend to approach the centre. So, if we flip the whole object upside down then the centre will be at higher level and the marbles will automatically go towards the corners which ar at lower level now. Well you can flip it by holding it above your head so that you can see the marbles moving to the corners....you know for self satisfaction😌
You are right 👏
Lock picking lawyers isn’t getting that lock open, I guarantee
For number 5, it changes the center of mass in such a way that the forks are being balanced.
The forks are already balanced.
#2 Questions answer The ring of screw was maded anti-clock wise that's why it is going upward
They just need to spin it in opposite directions
Вот так везде и наепывают нашего брата))) А кошелек в детстве у меня такой был)
Softened wood prior ( probably with water ).
I know the first one. You put the piece of wood in I think hot water and have pressure on the side pieces so it will shrink the sides and then you can put the nail in and let it dry and your done. Same kinda thing with number 8
5:00 This nut printed by 3d metal printer ^_^
:0
This trick has been around long before 3D printers.
7 th solution spin it so the balls will reach ends ( centifugal forces)
Wood is insulator, aluminum is conductor.
I would say perhaps the golf ball was dunked in liquid nitrogen, which would shrink it drastically. Once it warmed back up it would likely end up at its normal size.
4: product in reverse direction, form top to bottom maybe
HINT: When wood is wet, it can be compressed,. When dried it will come to its original shape! HINT: Ball into outer corners, just spin it!
@@BHAKTIBROPHY and CYCLOPS RESEARCH I had another solution, magnetism... if they are all staying in middle, just place a (circular if aval) magnet close, and just above them long enough to impart a polarity on them, then flip magnet from top to bottom, reversing magnet orientation to repel the balls away from magnetic field. A strong enough magnet would pin them away from center, perhaps using an electromagnet to be sure it worked ?
Impossible nail, separate pieces with magnet ends, hold each other up
The dovetail was fine wood craftsmanship. 👍
hey i love that impossible wallet it was very nice
I had one in a child's magic set 50 years ago:-)
2 Not a puzzle. Just two nuts threaded opposite each other.
You obviously don't know how threads work.
@@dhy5342 facts lolll. Easy enough to buy left handed bolts/taps tho
@@Zociety6477 take another look at the bolt. It has a left hand thread for its whole length. A right hand threaded nut wouldn't even fit on it. So why does one nut screw on toward the head while to other on screws away from the head when they're both turned the same direction? I know how it's done but it's not anything how you would guess.
@@dhy5342 i always assumed a left hand thread with the same pitch and size would fit on its right handed counterpart. Now that you made me think of it, thats a completely dumb thought lmao. My intrest is peaked now
6: all you have to do is turn the box upside down, shake it, and push the top off diagonally.
4. This puzzle was created by moulding glass. First cards and padlock with string was putted into glass jar then it was heated to mould into bottle by narrowing the opening.
The gulf ball in jar is done with heat and cold.
You make me in love whit physics
I feel like the impossible jar with a golf ball was simple, the jar was made around the ball and same with the impossible bottle and impossible arrow
Soak in hot water and compress one end off wood in vice. When cool, it will stay compressed enabling you to drill holes to accept the nail. Insert the nail and re-soak in water when wood will assume it's original shape. Then, just sand and lacquer it all up
Correct that is why it is not a hard wood.
The impossible nail is easy if you have the right tools. Like other tricks including wood, you just soak it till it’s pliable, use a vice to squeeze down one of the pegs on either edge (your choice) then hammer the nail through the two middle pegs. Allow the wood to dry and expand back to normal and voila!
Number one boil wood and squeeze it with clamps for 2 days now insert nail on it again boil wood it will take it's shape back 😀😀
Dose the like mean that the answer is correct?
@@strpasha looks right 😁😁
Heat the jar, the golf ball will fall out
3 - The ball was chilled
The jar was heated then opened then they put the golf ball inside and then close it
Sahi kaha bhai lekin mujhe English nahin aati karke comment nahin likh Sakta
@@kunalnewalkar6128 Why kyun bhai
You can see a metallic plate at the bottom of the jar in the video
... and the same time freeze the golf ball to shrink it slightly. May work
Similar to the nut and arrow puzzle, use boiling water ansd clamps
Crossroads puzzle: just rotate the board very quickly, the balls will gl to the corner due to centrifugal force
That would work, but only until the spin stops or slows down. Solution; TURN UPSIDE DOWN! since he mentioned each of the marble pathways are sloped to ensure they return while resting to the center position. *which is due to gravity*
@@darrelldawson4823 but if it is upside down they will be resting on the top which might not be sloped
Love these kind of puzzles
The forks and toothpick trick is because the fork handles point towards the glass, bringing the center of mass to the edge of the glass where it makes contact with the toothpick. When you balance it with a regular toothpick you then light the inner tip of the toothpick and it burns to the edge of the glass
2nd project solution Threads in both the nuts are on opposite sides.
You cannot screw a left hand nut on a right hand bolt. Try it, doesn't work.
@@physicsfun ya u r right 🤔.
@@physicsfun There is a vertical gap in the threads on the bolt. That allows the nut with the larger/different threading pattern to skip grooves somehow and turn in the other direction?
3:55 If force is applied diagonly to *impossible Dovetail* it will open
After cutting the wood in the shape you soak it in warm water for a number of hours now squeeze the end piece with pliers it will compress so you can drill holes in inner pieces and add the nail after it dry out it will take on it's original shape
The first one is an old woodworker's trick by steaming the wood and compressing it to get the nail in place. As it dries it goes back to normal. The golf ball is using a vaccum to pull the ball into the jar. The other jar, dunno. The forks use center of gravity and balance. The dovetails are cut at an angle so they slide the crossroads, you have to spin it. The arrow can be done the same way as the first puzzle.the knot looks like multiple moebius strip cuts.
1 put in a boiling water for few minutes and bend wood
Not bend but squish the outer 2 notches with clamps
Hello, I'm a physicist and love your videos, I follow you since you started on Instagram
Hello cice, great to hear :)
the wood and nail one and the nut on the arrow, heres how soak the wood in water for several hours, then crush the wood CAREFULLY with mole grips or a vice without leaving any marks. when its dry it returns to normal. another option (on the first one) would be to split the wood along its grain, (do not saw or cut), it will glue together good as new
9- Similar to the jacob's ladder, the dolla bill sticks to the next ribbon as soon as you flip the wallet. I did that as a younger kid, with my non functioning wooden jacob's ladder. 11- Just blow into the top piece.
