Other people say: "Don't try this at home." Tech ingredients say: "If you want to try this at home, be careful."
Yeah, it's noteworthy how they always seem to treat their viewers like adults. Instead of a dismissive statement like "don't try this at home", they provide a lengthy explanation of what to be aware of should someone actually try this at home. 🙂
I always have a fire extinguisher next to the workbench...Sure it may be converted to be a flame 'thrower', but the outside still has a 'fire extinguisher' label on it. What better way to fight a fire; then with more fire? ;P
But even better -- "when you try this at home, *use this safety gear and here's why*" I'm seeing a bunch of tablesaw videos finally getting around to that...
"Don't try this at home... do it at somebody elses home instead"... :-)
Unfortunately, "Don't try this at home" is the most effective disclaimer to absolve liability in our litigious society.
I would add some red laser pointers next to power laser beam as a warning cage. that would be more visible in the smoke.
Good idea.
@@TechIngredients next video: "we built a 10 megawatt red laser pointer"
If you're going to go with that @@TechIngredients make sure no cats are nearby.. the smell or burnt fur is bound to be unpleasant
@@arthurkortekaas7357 Crossover with StyroPyro when?
The red laser pointer is a good idea. Medical Lasers do the same thing. However it adds some complexity to the opticals. You have to combine the two beams and make sure they are aligned. Other the Red laser pointing one place the other one somewhere else, NOT Good! Ron
I love this arms race with Styropyro. Obviously a collaboration would be even better. Can't wait for the next video.
He'll go prime rib, then I'll go Wagyu... I know what you mean. He's a sharp dude with a PhD. despite his low-key approach. It would be a blast.
Definitely second the collab
@@TechIngredientsa collaboration between you guys would be the greatest thing in the DIY science community. The both of you are insanely talented and creative at what you do. (this video gave me Retro-Futurism type ideas. My imagination was seeing atomic era style commercials for portable camping laser cookers. Comes with a full safety kit, cooking kit and portable power kit. Lol) I'd love to see something like that even if it's not serious.
I was thinking Styropyro needs a dampener hanging in the center of the hunting stand as well as maybe guy wires to better stabilize and stiffen cost effectively. Tech Ingredients leaves me unremarkable.
He's young, still dabbling around and having fun. He probably working on serious stuff behind the scenes tho.@@TechIngredients
"You almost always know when you've had a laser burger because of the footprint" - Finally an easy way to differentiate between a burger and a laser burger.
"we're going to need all of them, stay tuned" Next video: "we built a functional Death Star"
My thoughts exactly 😂
“Bonus: it can also be used to cut salad”
@@AM-ui9mc Or start a campfire. "Let's go camping and be all low tech."
I hate the fact that nobody can have a conversation about lasers without blurting out something about star wars. it's embarrassing.
@@frydemwingz weird thing to spend your time hating, but okay
Long time viewer here I just want to say really quick that I appreciate how thorough this channel is about every aspect of a topic I know its probably a lot of extra work but it doesn't go unnoticed.. Thank you so much Sincerely random viewer
Appreciate that!
"They don't sponsor us. I just like it." Fuck, I love this channel. This channel is what KZhead should have been.
WOULD have been if the advertisers didnt treat youtubes audience like a bunch of five your olds in bible study.
@@lexinexi-hj7zoSeeing as how many shills there are on YT, it must be working.
@41:00 Somehow I get reminded of Bob Ross painting lessons.- "Tiny little strokes...I just want to create a misty impression...there you go...all the little light reflections..."
This guy is like Mr wizard times 10,000. He’s soo good at explaining things that I feel smart even though I’m absolutely not.
I love how he is explaining the process like everyone has a 300w laser at home hahaha. Brilliant stuff!
Good thing he after shows how to build one 😂
Yeah, we don't have that. Yet. YET.
@51:54 you mention the switch is based on a Silicon Controlled Rectifier (SCR) but it’s NOT. To clarify and avoid confusion SCRs are used to switch AC, not DC. The device you’re using is based on a MOSFET. I am not criticising or taking anything away from your superb content, which is absolutely top class. I only mention in case others really are building this stuff themselves 😂
I had the same thought and looked up the datasheet. Of course MOSFET😊😎
i’m going to continue living vicariously through your builds while i stay at home and amuse myself with my 3 milliwatt laser pointer. a man has got to know his limitations.
Limitations ? I feel lucky today , punk….
Amen, brother! Even if I could afford this sort of equipment to experiment with, I know I'd probably do something dumb and injure myself lol.
laser pointers carry their own dangers. For example, with an 8 lb kitten and a friend pointing between a dudes legs...
This is so incredibly groundbreaking. I worked as a technician with metal 3D printing machines and even some the engineers at our company didn't understand how the laser melting process works.
It was great how the laser made the oil fluoresce.
Let him cook! 👏🏻
I swear, every time those goggles started to fall down your face a little bit, or you turned your head with them hanging low on your nose, I was thinking - 'Didn't he just say that, without the goggles, he'd never see anything ever again?'
I was thinking the same thing
Usually you would use an elastic headband. He just likes to live on the edge.
It was giving me genuine anxiety watching that happen.
'We're going to need all of them' Best line of the vid 😂 Can't wait to learn about all this awesomeness
I’m I the only one nervous when he move around his hands arms near the frying pan? It’s basically a silent invisible bandsaw hanging in mid air
Closer to a sandblaster if you really think about it. ✌
I was concerned about those reflective tools he used
Not really as bad as a bandsaw when it is like this, it will just burn a small group of holes your skin, through the gloves or clothes. Not worse than a tattoo really, or something like a small brand. (As you can tell by the speed the bun is toasting)
@@rdizzy1 well, youre right about near the pan, but the focal point is still between the pan and the lens. He just carved metal with that thing. You think water in the skin is sufficient to stop it from going deeper? The sandblaster analogy seems reasonable, so yeah maybe not as bad as a saw.
If it was anyone else I'd be worried, but he's extremely competent and safety conscious
Closed container with rotary table - a laser oven.
Exactly. Retrofit a microwave oven to cook with lasers and not blind you.

Tech ingredients finally talks about my area of expertise (beef/ground beef/foodborne illness) and comes through with 100% accurate information in an area that is a minefield of folktales and bro science.
except he says he leaves the burger on the counter to get to room temp before cooking. big no no in the industry. at home its fine. but against health code for restaurants for good reason. Source: Am food safe certified
Did you catch the part where he flicked table mayonnaise back into the jar? Lol, still love this channel
When he said that he only cooks ground beef memium-rare, if he grinds the meat himself. THAT is when I knew he knew! Just wish I had a name for him. Even a made-up name. "Mister Tech, you are doing just fine!" steve
He's got to be one of the coolest guys you could ever know. Imagine being his neighbor.
4 am: why's the sun out already and how is it blue? Oh, that's just Tech Ingredients, he must have the munchies...
He'd be a pretty noisy neighbor though lol
"We're going to be kicking _everything_ up _a couple_ of notches" Alderaan is on notice
Here's an idea: Make a handheld version of the laser and put it into a sandblasting cabinet. Replace the glass with laser safety windows and add interlocks and ventilation. Boom, a safe laser cooking chamber with no PPE to wear.
A born teacher- transitions seamlessly between teaching about lasers and teaching how to cook a burger! lol
For those interested, better cuts on thicker steel are made by using high-pressure (usually 70+PSI) oxygen alongside the laser.
Its nitrogen for stainless and co2 + nitrogen combo for ordinary steel, at least this is what my local shop feeds their Trumpf.
@@VEC7ORlt what's the point for the use of oxygen? i get the point for nitrogen to prevent oxidation but it doesn't make sense the other way
@@vercingetorige400 burning away.
@@VEC7ORlt Interesting. I've cut some steel with oxygen, never used an inert/noble gas mixture for it before. Usually the cutters i'm familiar with are doing precious metals, though (that's where custom silver and gold plate jewelry tends to come from).
@@VEC7ORlt Steel is cut with N2 or O2, depending on the machine and thickness... Never saw Co2 used on two different brand/technology of lasers.
This is how the grill marks on the cheap deep frozen burger patties is made. Laser charring while deep frozen, in flight off one conveyor to the next.
I, I... want to argue against this so, SO badly, but know it's true or will be true in the next four to five years or less.
WTHeck? I had never imagined that. 🙈🥴
It's actually dye.
When I was in high school, I was pretty sure the grill lines on the "teriyaki dippers" were drawn on with a Sharpie.
Lol the replies are hilarious
Mistakes are inevitable in a kitchen environment, so the goggles on/off steps must be eliminated completely. Isolate the lasers in a cooking box that is only viewed through filtered cameras inside the box. For rapid development, consider augmented reality headsets with filters on the camera lenses.
Can we have some videos on rotation detonation engine its an interesting topic .🎉
I appreciate the time and work you put into your videos. Thank you. 🙂
You have such intriguing videos, love your channel!
As someone that didn't have a dad growing up, please cherish this man, he is everything a successful son wants and needs 👍

I love this channel. You guys do the coolest experiments.
Sous vide the meat, laser char the outside to perfection please. First to order the perfect burger. You can cook, kill ,burn with a old Flat panel t.v. screen too. It's very powerful. It can cut rock
Thank you for another awesome and very interesting video. I don't see myself messing with high power LASERs anytime soon, but definitely very cool to see. They have many practical uses as well. Anyway love your videos and how in depth they go. Thank you for everything you do.
this guy is Mr. Rodgers, Bob Ross, and Bill Nye the Science Guy wrapped into one.
We NEED that Styropyro collab! :) Great Video, i love that you are messing around with the systems you build. Grilling a burger while explaining laser systems... thats what i call entertainment! Keep it up! :D
Thanks!
I work with these systems on a daily basis, and it amazes me how many people feel that they don't need glasses just because it's a infrared and they can't see it. I've seen jewelers staring directly into a 3,000 W laser beam... no laser goggles.
Have you seen some of those sketchy rust removal demos where the operator is wearing sandals and no eyewear? Jewelers using 3,000 watts!?
@@TechIngredients Yeah, those videos can give second-hand OSHA violations. Yeah, gold and silver cutting stations sometimes have 3 kW fiber engines in them. Silver in particular is very reflective and needs a lot of peak power to get started, although once it melts it's more absorptive.
Infrared CO2 laser are less dangerous. You will have time to blink. But it will damage your cornea (which can be changed) Fiber lasers use a different wavelength and are more dangerous. But most infrared lasers are blocked by polycarbonate like simple security googles. And cutting lasers have super small focus points and outside of their target, the light is not super powerful. It's not like the optics of a laser pointer that can shoot a laser at 1-2km.
@@SilmarilS79 If you stare directly at a focused spot of infrared it will damage your eye. Also, maybe I should clarify- I work with yttrium fiber and ND:YAG lasers (1070nm and 1064nm), which are very much not eye-safe. People treat them like they are, though, because it's not visible.
This is my favourite channel on YT, you always make incredibly interesting content! :-)
I love the illuminating effect of the steam/smoke from the burger cooking. Really gives you a good visual of the focusing and defocusing effect of the lens. I'm glad you only got your hand into the defocused portion of the beam; that coulda been really bad.
Nothing better than Sunday morning breakfast with a freshly dropped tech ingredients!
If the metal sheet deforms and reflects the beam towards your goggles, how long can the goggles withstand the power?
We'll be testing that.
You sir deserve 100M subscribers. I wish my neighbors were half as cool as you.
I love these videos. You guys make solid content. Very digestible and entertaining while being instructive and educational.
I LOVE it when he says "We're gonna kick it up a couple of notches." 😂
This is definitely how Elzar would cook. BAM!
12:57 If you didn't have the goggles on.... Then you'd never see anything else ever again.... lmao!
It's just amazing how far we've come in "commodity" lasers and optics. That burger looked really good!
Adding a turntable to the setup would definitely help. Good job👍
I'm glad the sane doctor brown decided to ask himself this question
"We're going to need.... all of them... stay tuned" oh boy!
Yeah, I can't wait to see what that's going to be like!?
The surface block is also possible using a granite tile, I got some cheap odd bin tiles off a tile place, genuine granite, not composite countertop, that I selected using a light to select the 2 that had minimal waves in the light. Works well using this. Yes the thin layer of thermal compound is good.
An absolutely fascinating project. Thanks for posting this video.
This is fun! I have an old Lasertech L200 industrial engraving laser, 1200nM 200W pulse mode, 100W continuous mode. The pulse mode is much better for cutting metal since the pause between the laser pulses gives the vapourised metal time to expand & get out of the way. A continuous beam is wasting energy by cooking a cloud of metal vapour, rather than heating the actual metal beneath it. Cambridge discovered this when they were building CO2 lasers that could blast through concrete. That was 40 years ago! But i never thought of de-focussing one to cook burgers. You are by far the coolest science channel on YT😁
Thanks!
I wonder if food tastes in a particular way when cooked with blue light due photo chemical reactions. Ive noticed that very intense blue light when directed at surfaces with organic materials produce a particular smell, similar to the smell of putting a washed towel in the sun, so that makes me think food might have a barely perceptible but highly particular taste when cooked like that, specially due the chlorophyll in the olive oil because it is a relatively good singlet oxygen producer.
Did you see the oil fluorescing under the laser light? You may be right.
@@TechIngredients Yeah, when I saw olive oil was the choice (excellent by the way) I was actually expecting a significantly brighter fluorescence considering how powerful the laser is but still was nice to see it.
Hypothetically we could test this by comparing it to an infrared laser?
Looking forward to your "big build" I have personally played with this lasers in the past, and they are truly represent an awesome power to price to package ratio. Its unfortunate that over the past few years the price of them has more then doubled, but they are still a awe of engineering, especially considering how laser power has evolved from what i can remember them to be back in the 90's with just mw of output.
I simply love the projects you guys do. And the detailed, understandable explanations. And the vibe. You and Robert Murray Smith from Thinking 'n' Tinkering, closely followed by Integza, the plasma channel and Styropyro are my all time favorites. 🤩💪
Wow, thank you!
35:30 A note on using mirrors as a flat surface, I believe you should use the backside of the mirror! The front of the mirror is essentially just a sheet of glass. It is 'flowed' in the factory, and thus isnt necessarily perfectly flat. It is the backside, which has the reflective coating, which should be absolutely flat.
Think about it.
Prime styropyro collab opportunity !
Thanks for sharing your thoughts, ideas and videos. Great topic, thinking as clumsy and accident prone as I am I will be keeping clear of that one. Just as in welding, I’m perfectly happy to have KZhead filtering the light spectrum and power levels to my screen. 😂 always enjoy your detailed explanations. Not sure if you have ever watched the Illinois power prof channel. He has a great technique for displaying written text on his videos. Not exactly intuitive what he’s doing but it’s certainly affective and impressive. It’s almost hypnotic to watch and hilarious when you eventually figure out how simple it is to do. Wishing you and your family the best.
always love to see these. Thanks.
Please stop doing AI art thumbnails
I kind of like it. It's quirky enough and clearly depicts the subject of the video
no@@haloandrei
I don't mind it. I'm opinionated
I could maybe see your side of this if they replaced a thumbnail artist, but they didn’t
It looks fine, if you want to volunteer to make their thumbnails go ahead.
Ai generated thumbnails suck
Nice video though
Thanks!
Awesome work, I continue to appreciate the content you put out. Especially safety. It's well rounded and easily digestible. I look forward to future videos. I'm not gonna talk about lemons.
every video is just a pure joy! they are entertaining and full of technical information
The best tech / science videos with the best narration as always !
Tech Ingredients is easily one of the best nerd entertainment/informational channels on the internet. Watching an hour video like this is akin to having the (very detailed and with key examples included) table of contents of a college textbook concisely delivered with refined style: well done guys.
Now I want a burger! Always appreciate your videos. Thank you.
another great video! Excited to see you guys working with lasers again. I actually just got a new job working with lasers I start my training tomorrow morning
Great! Good luck and learn as much as you can.
thank you, that was a great video, cant wait for the next one ❤
Thanks! We're probably going to do a livestream next, followed by the upgraded laser and target tracking system.
Awesome work old chap !....cheers.
If you are going to do some more cooking: Mount the laser array in a modified version of your turret mount, so that it tilts maybe 2° in both axis a few times a second, so that the laser beams each sweep over an area and do not stay at one single spot. Should help against the burn patterns on patty and bun.
A couple of ideas to add to the convenience and safety: 1. Add a rotisserie style turntable, so it rotates in the XY axis. Possibly even the Z axis. 2. Add four red laser switches in a square pattern around the beam, so that when an object crosses them, it cuts power to the high-powered laser via a relay. With the combination of these two additions, you could just let the patty cook without interference or accidentally switching it off and you could add things like cheese by just crossing the red laser beams and adding it without having the cooking laser on while doing so.
Didn't knew I needed this video but I couldn't stop watching it.
Master, thanks for the explanation and warning.
Not only is he a brilliant engineer, but also a good cook. Impressive Great content.
TBH he seems like the guy who could be an expert at anything, but he just follows his interests
I'm really looking forward to the next video!
I feel we're quickly approaching the breakthrough we've all been eager to see, sharks with friggin' laser beams.
the feelings when engineer spend hours making laser-powered oven, but will not take 5 min to mount rotating dish from microwave in the base.
Bro... you guy have out done yourself on this one.. Looks like your having way to much fun over there.. have you though about opening a burger chain? "Laser Burger" might take off ? 🤣
Wow, the "to demonstrate the magnitude" shots were amazing, I was genuinely going "Holy shit" while watching them... thanks for including that!
another absolutely stunning video! love it!
Man I would kill to be able to mess about with the gear you guys use. Safely, of course. I value my limbs and eyeballs.
One of the top 10 channels on KZhead, simply amazing.
GREAT STUFF AGAIH!!!! Welcome back!!!
😁
If there wasn't aluminum involved I would suggest trying it with "Thermal Grizzly - Conductonaut" . It's a liquid metal "thermal compound" with nearly 80W/m2K
this made my day thank you
Hi Kris, thanks for an interesting channel - I really enjoy your ingenuity, originality and grit. Great variety and problem solving too. One small suggestion - I think the entertainment value would be greatly enhanced by showing time lapse photography for repetitive tasks. Thanks again 👍
For cooking with a blue or violet laser, I would rather consider using food-grade high temperature silicone oil, instead of normal frying oil. First of all, light doesn't have a particular temperature. Everything depends on absorption. Further, oil has a very low thermal conductivity. Overheated oil can turn in to benzene, acrylamides or formaldehyde. In short, not the very healthy stuff. Additionally, many people forget, chemical covalent binding energy can not only be overcome by heat-energy (E=kB·T), but also by blue light (E=h·f), that provides already a couple of eV (Electron-Volts) to the bill. Since all sorts of energy add up, decomposition of oil can already start at low temperatues. Therefore CO₂-Lasers are preferable, due to their much lower photonic energy at the wavelength 10.6µm.
I'd be interested in seeing a version of this where the laser is under that pan. Back to a more conventional "heat the pan to heat the food" method. As it is much safer. There could be a induction like safety sensor to remove all safety glass requirements.
Once again you never fail to surprise the viewer. Keep up the good work sir. Applied science indeed : )
For your SSR / arming circuit, you may want to consider using a safety relay. These are used in industry to manage emergency stop circuits and redundant - But more than that, they are self-testing. They use a pair of relays with force-guided contacts, which means that the contacts within that relay are forced to move together. These relays usually have normally open contacts for the device to be isolated and normally closed contacts for the monitoring / self-test functionality. The normally open contacts are connected in series for redundancy. Usually they are used emergancy stop switches which have two separate contacts, again for redundancy. The clever part is the self-testing - This uses the two normally closed contacts in series as part of the reset circult. The separate reset button / circuit is used because this ensures that both relays are working correctly before allowing the system to be armed, preventing the situation where a single relay has failed closed but is hidden by the second relay. It ensures that you always have two layers of protection. I think that this is important in this application, where you need to be confident that the laser has been turned off before removing your safety glasses.
Thanks for the suggestion. I'll definitely look into this, especially as we move toward more autonomous computer control over the system.
We used these same setups for heaters that got up to 1500F. 2 sets of 3 phase mechanical relays with a solid state doing the switching on and off. An ammeter was placed after the solid state, and a tolerance programmed in due to SSRs leaking a small amount continually. If it exceeded the tolerance when the SSR was supposed to be off based off I^2T, then the mechanicals opened up, and on went the alarm
Love the explanation of the set-up. One point you brought up is safety and I agree....Don't cut corners. I found out the hard way and yes my sight is fine. I a bit of welders burn from cheap goggles. On the down side the experiment was a failure.
You can totally see the beams diverge in the smoke looks 👌 awesome
Lovely video. When lapping the water block its good to use a blue marker on the surface. Lets you see the the highs and lows easier.
Thanks. I used to do that, but the scratches are so easy to see. It turned out to be unnecessary.
The seriousness of the discussion while cooking the burger with a laser that will cut a car in half is just spectacular
cool stuff as always 👍
This is my favorite cooking show
if you ever do a followup, I would reccomend doing a reverse seared steak/kabob. cook the meat in a sous-vide immersion cooker and then you just need a brief touch of super intense heat to sear. like 10-15 seconds if you have a really ripping hot heat source, which you def do.
Finally a proper explanation how to put thermal compound properly. Thank you. Hope this video get 10M views so people finally learn 🎉
“Centre” the exciter so that it sits at 60:40, on both x and y axes. That was what Tech Ingredients found to be the best position for them to be placed. Great shorts! I am now considering doing something like this, myself 🥳🙌
