So, basically, if you see a huge flash of light outside, get away from the windows!
You'll be lucky if you can react that quickly... if you see the flash, its probably already too late.
@@Nemoticon Depending on it's size and other things...
@@mana3735 If there's enough energy to create a shock wave, it will be right on the heels of the flash.... unless you're like 20 miles away ofc
@@Nemoticon I'm just going by the Russian one a few years ago
@@mana3735 That one was quite a shocker!
I watched a meteorite explode while stopped at a traffic light twenty years ago. Believe me, when you see that, you never forget it.
1:21 whoever animated this should be fired lol
lol didn't notice at firts, wow asteroid burning in space
Respect for the sound effects as well!

You go, Dan! I'm so proud of him! I was an undergraduate in UF's astronomy program when Dan was getting his PhD.! He might not tell you this, but he has the reputation of being a master at accurately recognizing and classifying stellar spectra. 😁👍
The air cannon was aimed directly at that office window. The real blast would have been directed at every square inch of the building.

... and doesn't cover it.

I think the scientific name for it is " The Chippendale Effect".

Lol
Dislocated and broken shoulder, worth it.
His voice... I keep expecting him to say"ALIENSSS"
it amazes me that there's actually people on this Earth that thinks that this is not a real threat and should not be taken seriously. A deadly asteroid could impact our planet at any given moment which is why we need to take these studies more seriously and figure out how we would approach a potential Hazard such as asteroids.
@@joeaverage8564 You gonna help?
@@joeaverage8564 The sun will not go supernova, it will enter a red giant phase and then collapse on its own weight into a white dwarf however an asteroid is very likely to hit Earth before that happens, I'm willing to bet that there will be plenty of cases of catastrophic asteroid events that will occur before that happens and I seriously doubt that Humanity will be here within the next thousand years.
@@LucidVision138 Yeah, far out.
Warning shots. I remember a narrator stating that the dinosaurs had warnings by many earlier arriving smaller meteors, and I ponder if what we are seeing is abnormal. Note 6:10 the rolling cinder block. The pressure wave would have been across the entire wall, not just the window. The entire wall would have collapsed across the room. Reminds me of the nuclear blast films.
"the universe sent us a warning shot"...What?
No joke, you could be walking down the street one day and see a fiery smoky trail in the sky travelling at thousands of mph. You will have only seconds left to live.
Lol I’m pretty sure we’d know in advance if one were headed our way...
Yes, a 45 degree angle would have produced a much greater over-pressure... over a far smaller area. The Chelyabinsk impactor produced a decent over-pressure over a wide region. All things being equal (size & speed) the greater over-pressure means a smaller area effected since it's to dissipate the same amount of kinetic energy.
It's not the same amount of kinetic energy. Exploding lower in the atmosphere means the atmosphere absorbs less of the energy because there is less atmosphere between the ground and the explosion. The area might be smaller, but not a 1 to 1 inverse relationship to the increase in the severity of the explosion.
@@markpoidvin5382 IT would have been really really bad :)
hence, the butterfly shaped damage path
LOL the look on the crash dummy's face at 5:00 is absolute traumatized submission
Nah, looks pretty chilled out to me..... like he's just looked up and realised his shift is over, deciding what take-out to get on the way home!
2020: Intresting! I will look into it
I wonder if the direction of both the Tunguska event and the Chelyabinsk event were similar? I have tried digging that out on the Internet and not done well. Is there sort of a favorite direction that these things come from?
Saw a super bright bolide, tarpon springs fl. it must have landed in the gulf of Mexico miles off Clearwater Beach. This was summer 2016. It lit the night sky like noon for about 3 seconds.
Size and angle are of course very important as to potential in regards to destructive power. But so are composition and velocity..

5:12. "Helga- where's my coff-" KABLAM! Guy blasted across the roof, office a total wreck. YIKES.
4:46 Dan looks like the guy off of Reno nine-one-one, the cop that wears the real short shorts lol..
Our deepest condolences to Mrs. Dummy & the little dummies.
Love how they pointed the cannon directly at a public road. You know, what could possibly go wrong lol.
This must make flat earthers retreat even deeper into delusion thought
Indeed.
The strikes never happened, there all cgi. 👍
@@paulthomson9709 Yes they do. We've observed them and have seen the craters. Your cgi claim however is only in your imagination.
@@grapeheart7440 it's called sarcasm .. of course they are real
Stop trolling.
could i take some scene for footage
What is the dB rating of the air cannon? I thought he should use ear protection.
So far it appears that all small asteroids that have exploded in our atmosphere have totally blind-sided us. Even with all our telescopes and equipment for scanning the skies, it appears that actually spotting something inbound before it hit, would be just sheer dumb luck.
Yup - two reasons: One is that our telescopes are not as powerful as we think when it comes to "small" fast and dim objects. The second one is that we don't have nearly enough of those telescopes to cover the sky - and those that we have are almost always doing other things - telescope time, especially for those very powerful ones, is extremely expensive and when someone does get it, it is usually used to hunt exo-planets or some other distant, large and bright objects, not some rocks in the Solar system. To detect those before they hit earth, we need actually something bordering a sci-fi - a planetary defense early warning grid of satellites who's sole purpose would be to scan around the Earth 24/7. Then, you can maybe hope to see one before it actually hits.
Many of your comments are extremely intelligent and interesting. The futility of an asteroid is that when it is upon you, wherever you may be, just take cover and hope it would not be a direct hit. Be it known, however, you may not have even had time to RECOGNIZE, of what it was that descended upon you.
the last blast is kinda accurate, the only inaccuracy would be is the blast woul;d be over a larger area than the single blast from the gun. that wouldn't just blast through the window, it would pressureize the whole side of the building knocking it flat. yes we should be very worried.
What about all the debris being carried by the wind/shockwave
Dan Durda has the coolest job on this side of the Galaxy.
In 1989 me and 3+ fiends saw a huge asteroid skim the Earths atmosphere and "bounce" before heading into space. It was low enough to see what it was complete with huge pock marks and "peanut" shape. The front was glowing white/orange/red so it was low enough down to start getting some serious friction. It was observed from Wagga Wagga Ag campus just as the sun had gone down and it was in the Western sky where the sun had set. Given the distance it must have been and how clear it was this thing must have been massive. It left a smoky trail behind as it moved (and it was moving fast) but it was quite feint. I think the Earth got very lucky on that day! The other odd thing was it clearly "bounced" or deflected as the angle was very low and almost parallel to the horizon. Away wondering, some of these big asteroids on the watch list that we have data for... if we wind their orbits and trajectories back into the past (not future) were any of them close in Late 1989? (ie. looking for a large peanut shaped one that has a nice smooth front).
The sound of the cannon sounds like a real shockwave or impact that is terrifying
well yeah, it's an air cannon
How about 1998OR2 Asteroid with 4,1km diameter? Next on April/ may 2020?
someone had a rough day at the office...
Glad I found out about the sonic boom and possible exploding in mid air. Duck and cover while it flies over, got it. I will defo put this in practice on April 13, 2029.
that asteroid is going to pass by us by like 15k miles. Hopefully hahah
Bring it on ! Let’s keep it real.....
5:16 notice the cinder blocks are not back filled with concert and no steel rebar. That's not up to building code.Well maybe in Haiti.
I'm not here for the science I'm here for the destruction,. This was way too cool dude
Good example but it is definitely different when you point an air cannon at something.
Yes, the difference is with that size of asteroid mentioned, the angle of descent that favors it's most strongest power, the impact would've been tremendous than that of pilot test, to a point where you surely would save a good amount of money from buying a shredding machine for yourself.
@@imllendream k
probably not only windows would have been breaken. If Chelyabinsk would have exploded at a more less sharp angle it would have caused the same damage that was done on Hiroshima from Little boy.
where can I get one of those air guns?
Where is the casualty count estimation?
Cinder blocks are pretty hollow and weak, unless they're filled with concrete and rebar. Shatterproof windows might help reduce the amount of glass shards from flying around.
Or like auto glass that shatters into mostly harmless square chunks.
3:07 - What swag. Hands in pocket while falling.
Dave secret is that he spent his time getting a Ph.D so he could professionally have the excuse of blowing up things. Great plan Dave
I had a dream about this a while ago, it was hellish
Cool, share it. Reality, is hellish to me.
Gd to see that only a couple of cars were driving by on the road directly in the path all the debris he caused to fly off the car and gravel floor during his experiment went.
Now really crank it up, dead on impact. I'm just getting started !!!!
Like in Armageddon,,,, I had front row seat...
As I am driving in the background, he is shooting his air cannon off. Thanks for the scare
Why are you listening this while driving? Don’t be a liability.
I had a very real dream where i was standing with a group of people including my brother outside when i saw a ball of light in the sky the next thing i know is after impact a wave of fire was coming at us i told my brother, bro were gonna die and braced for impact. After being ingulfed in flames and accepting death/wondering what i was gonna be next aka the after life i woke up. It was one of the most real and intense dreams ive evee had, the funny thing is i accepted death and anticipated the after life only to wake up and still be alive.
that's freaky dude.
@@kkjppt5359 I've had dreams where I thought I died and woke up. Usually they involve falling from a height. I don't usually remember my dreams though. I used to remember them a lot more as a kid. Flying dreams are the best though. I haven't had one of those that I can remember at least for a good 10 years.
That was awesome!!!!
nice air cannon
That's a lotta damage.
3:00 how i feel when someone sneezes on me
Teller sounds like Solid Snake 😮
My man Dan the dummy got the tear back cannon shot🤣😂
Thank you for showing me what an asteroid impact would look like today. I remember the last one I saw. It didn't look like that at all. And I'm sure the one tomorrow will look much different than the one that might happen, today.
This is why "duck and cover" is a good idea.
Thats all I got so thats what Im doing
I'm shocked by the statement at beginning...: "... since the past 12 years there where *several dozens* of impacts of enough energy to devestate big city's" I'm quiet interested in this theme.... and even if the impacts are located in regions with almost no population..... I've probs to kinda believe that !?
You have to remember that 70% of the Earth's surface is covered by water. So, many of these events happen far out over the ocean and hence go unobserved except by remote sensors.
watch this without sound and try to figure out what's going on with the experiment lol
5:17 That´s alot of damage.
Ok I agree that we have been lucky so far. However that test at the end? Was no at al accurate. If that had been an actual office inside a building, the shockwave would have definitely done some damage, but the wave would not have been able to pass through so quickly as it did, vie to the fact in a closed space the pressure inside would build up to cause overpressure harm to living beings, but I doubt that the dummy would be thrown across the room like that and all the stuff so far! Just think about what happens on a windy day, you are in your bedroom with the windows open and the door closed, when all of a sudden someone opens the door to your room, what happens? Well the breeze and wind come blowing in through the open windows and glows all over the room, it may even blow the door shut! With a slight increase in the atmosphere\air pressure inside the room, but anything flying around would drop.
of course the cinder block flew off, look how crappy they made the wall
that might level a building
Now that I see this, I'm really upset when I saw this incredible event on the news they were smiling n cheery like "aww look at the cute little asteroid wow" and mentioned Nothing about ppl being hurt or destroyed buildings. This is why BBC news is better.
At a explosion/rapid expansion ALL the parts involved go further and further away from each other !!!!......no chance of forming planets etc !!
0:33 Never eat raspberries!
I wonder what angle Tunguska was. What about the Dinosaur Impact?
tunkguska was recent
I would have liked to see the affect on a person standing in the open. That first dummy was stopped by the car, imagine that blast hitting you as you were walking in the open.
Would likely destroy your lungs
0:33 Putin 12 hours after eating Taco Bell
4:18 so thats what happened to my garage the other day when my wife farted
IDK why I was laughing 😂😂💀 Seriously though, in early April 2 hit eastern Russia that we're 10x the power of Hiroshima. We've been fortunate.
It was probably the size of tje Tsar Bomba so it would have killed a lot but it wouldnt be the end of the world
We can only hope a big one hits soon
Especially if takes out the USA, homeland of the North American Corporate Empire, a.k.a. Pig Nation.
I wonder if that's why President Trump has the Space Force to protect America , and the world .
Ooo,Chelyabinsk meteorite 0:15😅
You blew up an orchid, you monsters 😅😅😅
12 more years baby wohhhh
Dan: the last guy you want to be with in the event of an asteroid strike because he’ll be the only person hoping for total destruction to justify his life’s work. I picture him standing behind someone narrating the impact in a play by play manner!!! Smiling emphatically before he dies!
Gee, looks like the archiving staff are going to have to work a little late tonight.
4:22 Cue Michael Jackson Video
Thats comedy right there
I want an air cannon
4:28 ---------- The chorus line in an RMB video -- when the shirt get opened to reveal the six pack and drop the lines "I'll make love to you ---- like you want me to"
Ouchies
If that wind machine it went any harder than that then the guys pans would of came right off!
Know matter how you look at it the damages would be mind blowing.... Just stay away from bright flashes in the sky and take cover....
God help us all when the big one comes
Once the people went to the gate....They fallen over a metal gate
If I were you I would start researching the sons nova cycle.
Well this video is reassuring...LOL
Hey! My Volvo!! >_
6:05 prevent how?
We can move asteroids out of the way. The most likely way to do it is a gravity tractor - put a small ship next to the asteroid and over the course of a few years, it'd move the asteroid slowly so that it would miss the Earth. If it's too late for that, we'd just smash something into it to push it
That would be a great non lethal tool for law enforcement use to help control riots and such. And for firefighters to help turn off fire in buildings or to blow through a wall with out explosives. Pretty sure there are more useful ways to use it but thats all i got. Blessings.
It’s a Chuck Norris Sneeze Simulator
Yep. This is what shock waves look like. Nasty, brutal and very very fast, no time to react. You never (or at least rarely) see this in movies - instead slow mo, flames, smoke, low frequency roaring explosions and people having time to brace and protect themselves, especially the main protagonist. Would be much more realistic to see people looking the wrong way in such situations and being instantly turned to goo with no flames and a 'snap' sound. But people don't want to see grim reality do they?
What if they military used that air cannon but used an artilarry oof
Moral of the video: If some freak pulls up in front of your office with an air cannon pointed at you, get out of the room! Directed air cannons appear quite deadly. Now what's that got to do with asteroids? That's not a good shockwave model.
no but it reproduce the pressure that office received...your lack of understanding or lessening properly to the video is astounding.... and if you want to be pedantic, the office had only 2 walls (front and back) no roof no door, so the internal pressure was not shown. so it actually only show what the initial wave pressure would have done in the first 4 feet inside the mock up office.
@@marcoflumino All pressure was directed from a single point. A shock wave is a wall of pressure. Taking into account the thermobaric effect (and subsequent vacuum), it takes far less pressure than this to cause death. Therefore: This is a poor model.
We are very lucky it was only 60ft in length.
Somebody is into the kabbalistic mysteries.
That time 2013 almost ended everyone
