Is this why storm troopers wear white armor?

[@dillonmcinerney9104]

***** yah but does it ever work?

[@ErikGsson]

Kaan Tüzün Smartest comment so far.

[@smartereveryday]

@MarvinsDadd It's a Class IV LASER, which is classified as a fire hazard. "Super Duper" is the term you should use when describing it. It's uses 3 diodes that are collimated to create one very very strong beam. We can't see the beam with our goggles on, we just practiced knowing where the beam was and were EXTREMELY CAREFUL. This is over 3 Watts of Optical power (not electrical).

[@Slingshotchannel]

Great video... seems like an idea for a cool living room lamp! A hanging balloon and a fixed mounted laser.

[@smartereveryday]

@rozeautopet Noted. I'm so sorry!

[@fkn666]

My son says to say he loves Smarter Every Day, and to "make sure Destin keeps making them!". Cheers!

[@smartereveryday]

@KimGyunAh The color is relevant. Notice it took the blue longer to pop because it reflects blue light.

[@smartereveryday]

@adcuz um, no

[@smartereveryday]

@scottboggs Dude I LOVE Joy Electric. Old school-new school

[@smartereveryday]

Negative. Straight out of the camera. The auto white balance setting I had it on didn't really know what to do when the room was flooded with 445nm. There wasn't a "Laser that burns stuff" setting.

[@Iampatrix]

I like how people in your videos are typically genuinely having fun. That's important.

[@smartereveryday]

The room was insanely bright. It was blue though, not purple as the video shows. That's a function of the camera's white balance.

[@smartereveryday]

Yes. This affects the value of flux... or radiation per unit area. Since this laser diverges, the closer you are the higher the flux on the illuminated spot.

[@smartereveryday]

@Xxnightwolf66xX I know the answer to this.

[@nonamesleft31]

This is one video I would like to see caught on high speed camera. Really interesting stuff, thanks!

[@AndrewPseudonym]

Great video. I already knew that light worked like this, but it was lovely to see a demonstration.

[@CuriousContent1]

the white balloon popped, why?

[@CuriousContent1]

Yeh a think he did tbh

[@Rj-cf8eh]

james bolton you can read the description, he popped 2 white balloons, one was because it had black writing, and the other one was squeezed

[@CuriousContent1]

Robert Jiang true

[@ravioli5802]

I already knew this and i now feel very smart

[@TheRecca99]

Best episode yet. Can't wait for the others

[@Xxnightwolf66xX]

hey destin,I love learning new things and one thing you haven't mentioned and what id really like to know is. whats the effective range of this laser? and by that i mean at what range will it stop popping those balloons? also thank you for taking the time to make these videos for us. much appreciated!

[@smartereveryday]

It requires it

[@mrericsully]

Awesome demosntration

[@drmaudio]

Nice demonstration. I never thought of the color of the target effecting the energy transfer. Of corse it makes sense now that I think of it.

[@smartereveryday]

@atomdragon4 He squeezed it. Watch again.

[@oscartigwell]

Coolest SED video ever. Thanks Destin!

[@LEARNTOPLAYCRAPS]

Super sick!! Thanks for Laser Month!!

[@PaulCarter]

This is great! Thank you!

[@Rogerthat5x5]

That was awesome. you two were having too much fun.....nope there's never too much fun!! Thanks for sharing, take care.

[@siddhantloya9587]

All ur videos .. are a very good resource of knowledge dude... hats off

[@chicky111893]

That was truly fascinating!

[@AmiaRavenne]

Man keep this up you inspire me to learn!

[@AmyLuthien]

Thanks Johan! Thanks Destin! That WAS pretty cool!

[@ALMOSThadthat]

it looks really cool when you pause video with the laser on the balloon right before it pops. it lights up the whole room!

[@worstcaitlynmain3925]

Actually black in Dutch is spelled Zwart not swart

[@ramonhuizenga4697]

Ja klopt hahaha

[@jt76801]

Impressive. Always enjoy the videos, keep it up buddy

[@smartereveryday]

@MrTonvegas Blue balloons reflect blue light.

[@Zralf]

that looks like so much fun !

[@greeneyedutchman]

I'd like to see the wall the laser has been pointing at, or at least what was left of it. Dank je wel man! Het was leuke filmpje.

[@AndriuXs100]

Destin, your videos bring a smile on my face :)

[@raulp123]

Wonderful video. Tnx for making it. Get smarter every day :D

[@tomzhou7259]

How much fun does this guy have?

[@brando132]

Now to the reason why the white took longer is not due to scattering, but to diffusion. as Johan said, it does not absorb as much energy, just like shirts in the summer, white shirt lets you keep mostly cool and a black gets hot really quickly in the sun.

[@joeandbuzz]

Dang - More sweet goggles that we don't have! Awesome video Destin.

[@atulkhanna001]

wooow that was amazing and thnxx for tell these stuff

[@smartereveryday]

Home made 3 diode.

[@yashashweechakrabarty9534]

We have formal laser training. *Starts randomly popping balloons for fun*

[@imi___]

I would not have expected that. Wow.

[@BluefanNL]

@MOEPBIBER In this case that white one had something written on it, normally the white ones don't pop even when you hold them in long enough. They loose enough of the heat by conduction/convection not to pop.

[@BluefanNL]

@JOZZIE52 The goggles have an orange/red color. They absorb UV light, blue light and green light while passing yellow, orange and red. The filters in the goggles are made of a special material that has this color specific absorbtion.

[@vanmaren962]

@Bombomb No I was actually talking about the one at 1:43. It clearly took longer to pop than the others but inevitably did.

[@samuelxu6878]

wait a second... how come the white one at the very end popped??? A 7:51, where they are popping balloons like crazy... there was this one white balloon and it ended up popping?

[@MegaJehanzaib]

+Samuel Xu Read the description.

[@weepingthunder]

This is the coolest show on youtube

[@sopaz]

@Xxnightwolf66xX The heating that popped the balloons is related to the power density of the laser. How much power you have per area. The laser here will be slightly divergent, so the spot size will increase the further away you go. I'm sure you could see the laser for miles, but at that distance the spot size will be much bigger, so you won't get the same localised heating to pop the balloon.

[@AtheerAl]

never knew that.. brilliant..

[@RacoonProds]

That white baloon with the laser in would make a killer night stand lamp!

[@korvys]

@mrrsmurf The white ones don't pop because they are light, but be cause they scatter all wavelengths of light. A red balloon scatters only red, and absorbs the others (and heats up and pops). A blue balloon scatters blue light (like the laser) but not perfectly (the colour must be slightly off) so only absorbs a little.

[@MW3GlitchSA]

I speak Afrikaans and the name and spelling of most of the colours is actually the same in my language because my language is derived from dutch.. So cool!

[@KhanggiTanka]

Jacques PienaarHey yes thats cool i know a few words zuid afrikaans and when i hear it i can almost understand it i know bees is uuh koe i think and blaai om means that are supposed to look on the other side of the paper dadilik is RIGHT NOW amper broekie is a bikini hmmm i know w few more but im not sure about them do correct me if im wrong

[@jumpander]

Jacques Pienaar It also sound like German. And I should know, because I'm german. In Germany the colours are spelled like this: -orange[o:ran~sh] = oranje -blau[bla:û] = blauw -rot[ro:t'] = rood -gelb[gä(ae)lb] = geel -grün[gruen] = groen -türkis[tuerki:s] = toorkois -schwarz[shwa:rts] = swart -weiß[wa:îss] = wit

[@NielloEd]

this made my day))))) thank you

[@TrailRat2000]

I want one for xmas!

[@ButtKraken01]

Amazing!

[@TheTinkaniea]

I'm Dutch too! ^-^

[@PeterVanSandt]

I think you could make a few hypotheses about the length it took to pop the balloon, the white obviously took the longest, the blue next, then the turquoise, not sure about the rest of the sequence but I think if you looked at them, the ones that reflected the most blue/violet light would last longest (white obviously being the most blue), so I would expect cyan and magenta to perform very well, but yellow, red, and green to perform poorly..

[@Kingjay814]

@yudy92 I think that particular one in the video would cause some serious damage, Right at the beginning of the video they were making sure it was aimed at a brick wall. Lower powered lasers wouldn't do anything, but something on that scale yeah I think it might leave a mark.

[@ohgruttjes]

@johanreinink dat is inderdaad veel! ik ben zelf ook een laserfan en ben aan het sparen voor nieuwere en krachtiger lasermodules

[@stevenbridge4651]

So the defense against laser weapons is not more kevlar, but white balloons? Dude! Its about time you had a sit-down with the US Defense Contractors! :-)

[@mrkiky]

defense against laser weapons is a mirror.

[@bionic5562]

***** not if you have a strong laser.

[@mrkiky]

***** Depends on the reflectivity rate of your laser's particular wavelength, the heat dissipation capabilities of the mirror as well as its melting point. But in any case, I assure you a kevlar vest has a much higher absorbtion rate than a mirror. Say you have a 1kW laser. Only 50W will be converted to heat and the rest reflected. If your mirror can dissipate that it will stay intact for any amount of time. A kevlar vest will be heated up with probably ~900-950W and start breaking down when it reaches 500 deg C. Of course if you have a powerful enough laser you can melt and burn anything because there isn't anything with 100% reflectivity. It's just a very very ineficient way to do it as 95% of your energy is merely reflected away.

[@Elmo187]

That would be a REALLY awesome way of lighting up a place for a party.

[@JediSentinal]

dutch/swedish people have *the best* sense of humor ever. lol i know a swedish foreign exchange student and he is hilarous, just like johan here lol. :D the way they just say jokes in english just cracked me up.

[@mr2octavio]

WAAAA, this is a very old video, impressive

[@BluefanNL]

@LaughingOutKraut First we shoot it at a white wall inside, which started to smoke, so we pointed it outside to a brick wall.

[@CuppaGi]

Makes me wonder why THIS wasn't the first thing my mind came too. Thanks :P

[@mrc109]

Destin, when you are wearing those high-dollar "laser shades", does it render the "beam" completely invisible to you? If so, I have wondered about the utility of wearing such eye protection if your work requires the physical manipulation of optical elements within the beams pathway (optical alignment, filter effects etc)? I have two small He-Ne lasers, scavenged from analytical devices, but I am reluctant to "play around" with them until I know more about beam safety protocols. mrc109

[@BluefanNL]

@helexable Correct! there was something written on it.

[@scottboggs]

Colors in Dutch is a song by Joy Electric. Look it up on grooveshark.

[@RonJohn63]

The blue and turquoise balloons took noticeably longer to pop. Thicker latex, or does it have to do with color/energy absorption?

[@matthewgrimsley4506]

RonJohn63 You see the "colors" (wavelengths) that a surface reflects (generally); so, it's absolutely because those balloons are reflecting more of the laser's light and absorbing less and therefore heating more slowly. Although material thickness, differing materials, and differing stability (of their hands) may have had a significant effect on popping time.

[@Hiwired96]

johan is een baas

[@Sclonez]

Oh man, It almost gave me an epilepsy attack when you put the fast speed. Anyway, awesome.

[@karateporkchop]

".... do you want to pop balloons with lasers because we can?"Johan ....best quote

[@BluefanNL]

@aquamus most camera's pick this high intense lasers up as more purple, it's really blue.

[@CuppaGi]

I assume the blue one took the longest to burst had something to do with violet being the shortest travelling light wave? Or was it just a very lucky balloon?

[@heyyoucharlie]

You know what... That was pretty cool. Thanks.

[@Razgriz__1]

The brightness of that laser in the video makes me wonder if the color was enhanced during the editing of the video.

[@industrialdonut7681]

if it was really a blue laser then the blue balloon shouldn't have popped either! if you notice it did take *longer* to pop than the previous colors but still heated up since the laser isn't the same wavelength as the balloon really reflects

[@Visiting_Price]

that was awesome and i love laser.

[@backhaendl]

This lion is really awesome!

[@BluefanNL]

@Johnson4o The laser is really blue, but the camera picks it up as slightly purple. Not all camera's do this though.

[@Kissaki0]

I’m interested in what happens if you put the closing, knotted end of the white balloon into the laser. Although white scatters the light, there’s much less „space“ for it to scatter in the knot. So it could potentially still heat up and weaken/pop on that end then.

[@233kosta]

If it was transparent to the colour of the laser, there would be no thermal reaction between the beam and the balloon. Eventually, the air inside the balloon would get hot enough to expand beyond the balloon's tolerance and it would burst, but that would take a while depending on the laser.

[@spoool]

Amazing.

[@helexable]

@mahjob it probably had a spot or some dirt on it and the light heated that up but they are correct white will prevent poping

[@AllenRKz]

Its fun popping balloons with light.

[@BluefanNL]

@BriteRavenPictures57 It's a diode laser, not a DPSS, which stands for Diode Pumped Solid State.

[@Wappie21]

@SezSays thnk u

[@BluefanNL]

@joosbawks it's blue, but the camera picks it up as somewhat purple

[@BluefanNL]

@alawrence89 There was something written on it that absorbed the laser light, at 1:52 you see me drop that white one because of the writing.

[@mrtalksalot]

i love the reaction everytime the balloon pops.ahahaha

[@daemonral]

@vegardokland Any reflection could be or is as powerful as the source laser. You don't want to risk burning out your eyes, if that laser decides to reflect off something.

[@BluefanNL]

@mitchem890 If you had a blue balloon scattering exactly the specific color of the laser it wouldn't pop. But in practice every balloon has some absorbtion, even blue balloon that scatter only the blue light still absorb more blue light than a completely white balloon.

[@DeeHolmes2]

Kinda Cool....meaning that in an awesome tone of voice.

[@JOZZIE52]

@Aviatorsmith Yeah but would be intresting how they tune it for the wavelength.. sureley there isnt a list of materials they mix in that blocks like a 5 wavelength range... if there is then thats a lot of differnet materials lol

[@KeeleV]

awesome!

[@wtfmandudeguy1]

totally saw that one coming, although i just thought it would take a little longer lol
