Laser Cleaner Lifehacks

from sunlight and a microscope to a laser chainsaw 🤯

There isn’t a single three letter organization that doesn’t have this man on a watchlist

I love practical lasers. That's insane! Also the Bad Apple at the end was lovely.

This man is on so many watchlists it’s like he’s collecting them like medals

Never thought we would go from simple sunlight to Super Advanced Laser Chainsaws. Wow!

Thank you for actually addressing the safety concerns in this video! It really goes a long way to show that you care!

You should double the laser wavelength with a nonlinear crystal, like green laser pointers do, a 2000w green laser would be amazing

“Florida Man accidentally cuts an entire forest down with a doomsday laser” is my new favorite news headline

The taking the safety glasses off to just reveal more safety glasses was a great touch

I'm an arborist, and one day, I hope there will be a light saber invented. That would be my favorite tool to use in a tree company. From tree to slabs in minutes ❤ Meanwhile, planting some trees along the way.

did you make the tree depreinter just for the pun? Or did you forget there is literally a line mode that does the same thing faster with the mirrors?

My main takeaway from this is that blasters from Star Wars can be real. And that Stormtrooper helmets probably had welding goggle lenses installed haha. How many of these would you need to combine to make a Death Star?

Man I wish I could afford one of those! I can see these being priceless in a body repair shop!

Kevin has gone from basic chemistry to making actual weapons. Quite the legend

I nearly spit out my cereal when I heard that really quiet "shake hands with danger" riff. What a legend lmao

This was epic Kevin. I'd love to see a tear down of the laser. What type of juicy HV we talking about here? Also - that plasma speaker at the end is just delicious.

I like how he carries on smiling, when one mistake could kill him.

You should do a test to see how much protection safety glasses actually bring. I guess, they are not there to make you stare into a laser but just to prevent the worst if there is some split second reflection from an object you use the laser on.

Damn.. I want one of those super lasers. Can you teach us how to make a small, cheap version of it?

I've been waiting way too long for someone to screw around on camera with one of these things. I just wanted to see stuff burn up, and you delivered.

Amazing content! I've been watching your stuff for years and I've gotta say, you've always been a source of inspiration for me to continue my STEM-related passions. Thank you so much for all you do 😁👏

In all honesty, honey is actually pretty good. Glad to see them sponsoring awesome youtubers

Is it perhaps possible to make it thicker, shorter and more compact

Make many, many, many more videos with this device. This whole project is a braingasm! Holy sh*t, am I excited to see what you do with this!

It’s very reassuring to see you using the full face mask. People don’t respect these tools enough, basic eye googles wont stop 2kw.

You can't just put that bad apple in the end and not tell us more! Excellent video as always!

Been waiting soooo long for someone to get a high powered fiber laser and screw around. Please do this more.

We use fiber optics lasers to cut thing gauge sheet metals at work. A laser can give a tremendously clean cut, if you flood the cutting area with a a gas like Nitrogen. Most industrial laser cutters will flood the cut with either oxygen to increase cut speed, or Nitrogen to increase cut quality. Would be interesting to see just how much of a difference the gas really makes, just a suggestion for a future idea.

okay honestly i did not see it comming that it would cut down that tree so fast, like i was like okay here comes the 4 hour time-lapse at least.

Dude, your videos are always top-notch. The science and the way you present it are always entertaining and informative.

I'm impressed that this guy is still alive. I like the "probably shouldn't do this but doing it anyway" attitude 👍

Man this is perfect! I was starting to think my chainsaw was becoming too harmless. Now I can burn, cut, and clean with the same tool while still looking like a chainsaw!

Loved the video. Thought, I was nervous that someone would wonder out from the house, and get hit by a stray reflection (melted aluminum is very reflective). Note that most laser eye damage is undetectable by the person. Your brain fixes the "holes" in the iimage, so blind spots are difficult to detect.... that is, unless you want to see each decimal place on your spreadsheet.

Actually a fun and cool fact when it comes to laser welding with these machines: you can have as attachment under the pistol a wire coil of filler metal of any type of metals following what you're welding, that act like a hybrid Mig and Tig welder. For thin metal welding, like, under 10mm, it's so clean with stainless steel that I see to reasons anymore to use a TIG welder, except in case of really large gap when you have to tack for initial assembly ^^

First experience with this channel...I like the vibe👊😎, subscribed 🤙

I love the hesitation before you just turn it on it’s exactly what I would do in your situation situation because lasers are too awesome for any warnings to contain it

I think your 2000W (Solar) square area is about 2X larger than it should be. 2 square meters (or yards) would be close to or over 2000W Solar, depending on time of the year, time of day, latitude, and clouds.

Hey good on you for emphasizing the importance of proper PPE. I remember in Physics 2 a professor told us a story about a Yag laser blinding a technician. He had moved his safety glasses up for a better look at what he was working on, dropped a wrench into the beam, and it instantly blinded him in one eye. All within a second. Lasers are legitimately terrifying.

"Haters will say Laser welding isn't as good as normal welding." That is single-handedly the coolest thing I've ever heard in any TRvid video 😆 👍

Thank you for advertising the safety third podcast, I was never quite sure what it was and didn't have enough time or curiosity to check it out. Now I think I might try to make some time to do that!

Honestly with a tool like this, that will surely be weponized soon (if not already) safety is EXTREMELY important here, this thing has some SERIOUS harm capabilities and I really think an EXPLICIT warning before the video "do NOT try this at home" always goes without saying, but should NEVER go unsaid regardless, especially when you (temporarily) removed the emergency stop button cap Keep up the good work! But remember safety 3rd is only acceptable as a joke! Haha nothing other than 1st, unless as a joke (which we know because safety first is also said when handling dangerous equipment)

Still kinda hard to believe just how powerful this machine is, but that Bad Apple at the end made me chuckle

I forgot it even said chainsaw in the title. It's just a laser video. Haha. Keep up the great content

Um, for someone who has worked in places like the federal reserve, one of the biggest counterfeits we see in the industry is people "washing" ink off smaller bills and printing the larger bills on them. They are usually really bad because its not easy to get the ink off, and they scrub so the texture is off. You just showed them how to do it better lol. One of the biggest challenges in counterfeiting is the paper

I'd just assumed you were gonna vaporize the sawdust from the chainsaw as it cut but I guess that works

Love this channel so much. That subtle SpongeBob joke at the end was the cherry on top of a pure gold video😂🙌🏻

It takes a lot for me to get horrified, and the zapping of the currency made all my alarms go off. I hope all is well for him, legally speaking.

When the plane passes overhead and he looks up, you can *almost* feel his thoughts... "I wonder if i can remove the livery off the side of that plane with the laser" :D

7:55 He was probably one of the first people ever to kill a spider with a lazer gun

You are now #1 on my list of people I'm actually scared of now. Congrats!

Great video! Would love to see Bad Apple in its entirety on the setup you have at the end!

I need more videos on this. This is awesome.

Which is more fun for you on tree trimming? There are chainsaw, laser, flamethrower, vibrating blade, explosive, gun, jackhammer

I’m interested to see if this works with bulletproof or archival ink!

would love to have one of these for automotive restoration!

The actual "paper" that money is printed on is almost impossible to recreate and unprinted it's extremely valuable, there's been cases in the past of people taking lower denomination bills, stripping them, and then reprinting them as higher value bills so I wouldn't be surprised if Secret Service came knocking lol.

Omfg, that was epic. One hell of a good video. You made my weekend for sure!

even though if you cannot see the beam is it still good for your eyes?... and what is the long term test on eyes at this light range?

It's surprising you can buy something like this. I'm wondering if dangerous things over a certain price aren't regulated much just because there aren't many people, who can and will spend lots of money on them for no particular purpose

Wow! that is impresive! Thank you for the great work in putting this video!

Kevin, can the laser be used to remove paint from wood? I have to strip 60 kitchen type cabinets with lots of detailed trim, so I'm looking for a fast and easy way to do it.... sandblasting is the leader for now.

Oh boy, I've never been so glad to be awake at midnight! Kevin: these laser heads cost a thousand dollars to replace so you have to be careful with them. Also Kevin: *attaches laser to chainsaw* Now that's the backdoor scientist we all know and love!

I watched some safety third when it just started but you guys are going crazy!

If I had one of these, I hope I would have a lot of fun before going blind. Growing up on a farm, I always wished for a magical way to clean up rusty equipment. This is pretty much it.

I think I would really like to use one of these. It's like power washing but with metal.

I never considered how fiber optic could one day become weapons grade.

That fact that this can be bought by anyone is absolutely astounding.

I am so glad the secret service still lets you make videos. I sure do enjoy them!

I dunno if its a recurring joke on this channel but I love that the "Shake Hands With Danger" song exists outside of niche safety videos from the 70s now. It slaps too hard to be kept in the past!

I just realised that with fibre-optic cables, having a laser turret on your house to shoot burglars is actually viable...

I wonder, what is the maximum distance this laser can penetrate one of the aluminum cans he pierced holes in? It might give some interesting perspective on the lasers the military carries on ships to take out missiles.

If only someone could fit the whole laser into the handle…. Then we could potentially have an actual effective laser pistol of sorts…

When the lasers takes 3 sec to cut down a tree, and becomes lighter, you can use them in forestry

Video should have been longer! Your stuff is the best!

I love these videos, never stop bro

I’m amazed that a laser that powerful is permitted to just be wielded freehand instead of being part of a machine like a traditional laser cutter or something like that

I mean... When Will asked for ideas to trim his trees I didn't think you'd have the answer that quickly

There's an iron pole in India that never rusts and I read that part of the composition was chlorine. Was wondering what properties a steel mixed with powdered chlorine would be, and steel and borax, and steel and chlorine and borax would be in blade form.

I want styropyro's thoughts on this thing now. or for him to come down there and overclock it / beef it up.

Another thing to add to my "Things I thought were super-secret military tech, but you can actually order it from Aliexpress" list.

Awesome video! Which laser power you've got? There are 3 options...

good thing about laser slomo is, you dont need to provide a powerful lightsource to compensate the short exposure time. a perfect match

I think it's a great tool to clean his own workspace too

thats by far the craziest, most epic and simply the best laser video i came across ever!! well done mate, well done!

This man using lasers for destructive purposes makes me truly believe that we're living in the goddamn future. Also, playing Bad Apple at the end caught me so off guard.

Now time to make it into a lasgun like those in WH 40k

Hi very interesting. Thank you . I think a laser is the best way to shoot down a high altitude spy balloon. Will it burn a hole on the balloon’s plastic skin from the ground? Or from 50000 ft?

Lazer welding is the strongest most penetrating welding process, I've never worked with it but I'm a welder and I know when a process is superior. It's the the penetration of a plasma cutter with unparalleled precision arc characteristic modulation. It's crazy stuff. Basically a mix of lazer 3d printing and welding.

I aspire to be this man when I grow up

If you are curious to how this thing can harm you when you can’t see the beam, it’s because it will burn your retina the same way it burns rust.

I need a full video of Bad Apple vintage oscilloscope version

Question for you: I've heard that lasers have a very limited range - they diffuse in atmosphere. How far can you shoot that thing and still have it cut something? (I'm a sci fi author, so this would be quite useful to know). Thanks!

nice safety third plug, you got the only parts of the show where you're not talking over eachother (I love safety third)

You can make a sort-of lightsaber with this, just get a laser dump that can handle that beam and attach it to the emitter on a long rod. Would make it much safer too.

I love that William ozman is a super fan of this man and now is on a podcast with him

I would love to see him try to make a brightly lit room dark with light

I love how you’re steadily becoming a supervillain. Truly an icon.

"I'm not exaggerating when I say my first welds with a Mig welder were an actual cognito-hazard." Boy, that takes me back to my first days of Mig welding lol

Laser is awesome. Make more of the rocket harpoon videos!!

the fact that you hit us with the oscilloscope bad apple at the end...
