9:47 what if you would put some food colouring in the water for your bubble, and maybe absorbs a bit more light.

Crank up the amount of different colours of food colouring as you go. Hopefully this effect will be noticeable before the bubble pops. Great video man! Nice collaboration

[@MartinThmpsn]

6:35 "Don't try this at home". Exactly my thoughts. I have persistent floaties in my vision from unprotected laser exposure in a lab at college years ago. That was a controlled environment where the laser path was protected and controlled, but my lab partner briefly fired laser while my protective glasses were off, and the black curtain that was intended to absorb the laser was down, and I caught some specula reflections off the wall. Watching these laser beams all around the room uncontrolled makes me panic a little bit.

[@olfmombach260]

Damn, you really got me there in the beginning

[@js267]

5:30 the reflected colors on the floor are amazing

[@neutronenstern.]

my intuition was that it could work for some reasons, if the laser was strong enough: 1. The photons of the beam could transfer an impact on the bubble if absorbed or reflected 2. The light could heat the bubble up which would cause it to go up again because of bojency 3. The laser could heat the bubbles downside up, causing it to vaporize and this vaporized water might be able to push the bubble up, also. Now to calculate how strong the laser had to be to move the bubble with its impact: P=m*V=5*10^-6Kg*0.01m/s=5*10^-8Ns The impact should be transferred in 0.01seconds P=h/l=6.626*10^-34Js/500*10^-9m=1.3*10^-27Ns If one percent of the light hitting the bubble is reflected or absorbed, transferring its full impact to the bubble, then the impact of the 0.01 seconds long photostorm should have an impact of 5*10^-6Ns 5*10^-6Ns/1.3*10^-27Ns=3.8*10^21 (Photons) These Photons would have an Energy of E=N*h*c/l=3.8*10^21*6.626*10^-34Js*3*10^8m/s/500*10^-9m=1511J So the laser would have to have a power of P=E/t=1511J/0.01s=151100W This is the power, the laser would need to push a 5*10^-6 Kg bubble with a speed of 1cm/s

[@CaelanStewartThePhpGuy]

It seems at that energy the water would vaporise explosively and cause a small pressure wave which breaks the surface tension and pops the bubble. If you had a near 100% reflective surface, or reflective enough that at the duration of the pulse and the given energy level it won't vaporise the material, it would work. It works for the same reason why solar sails work, doesn't it.

[@neutronenstern.]

@@CaelanStewartThePhpGuy yes what i didnt calculate with is, that the impact change of the bubble is double as high, if the light gets reflected, as it is, when the light gets absorbed. That is, because of in the case of a reflection the photon has got -P after the reflection , what ends in a delta P of 2P (P-(-)P=2P)

[@Hallowed_Ground]

Except that none of this works or matters because the bubble is transparent. Now, if you put some dye in the water you were using, it might very well work indeed.

[@neutronenstern.]

@@Hallowed_Ground not fully transparent. In the vid you could see, that it was also reflected in some way.Also you can see that a bubble is shimming red yellow ... . So because of intefferation (some light is reflected at the inside of the bubblelayer and some of it at the outside of the bubble layer and if the thickness is some (k+0.5)*k*Lamda it is destructive inteferrence. ) So this causes the photon to be absorbed. So there is indeed some kind of reflection and absorbption.

[@CaelanStewartThePhpGuy]

​@@Hallowed_Ground It is not 100% transparent. That means that there is always some quantity reflected, and some absorbed. It's why you can see the bubble at all.

Xx teardamage xX which would be a diffraction effect... see the answer in Seb‘s video 😂

[@murk1e]

Just as a piece of logic in the intro: “If it pops it was never going to bounce”. Not necessarily true. There is an effect with molten metal where you can briefly dip finger (obvious hazards here.... if you try and it goes wrong... it’s on you). Modest temps don’t give a protective vapour layer and burn, higher temps can work. Not all effects are linear. However, in this case, my intuition matched yours, I’m just being pedantic.

[@Okusar]

The Leidenfrost effect, where a high thermal differential creates an insulating vapor barrier between hot and cold surfaces. You can also see the effect in action by placing drops of water onto the surface of a very hot griddle and watching them skitter about on a cushion of vapor. It's definitely a much safer demonstration, though not as badass as dipping your hand in molten metal.

One super neat detail is how the bubbles don't have any dust in them. The beam has a slight fuzzy look when going through the air outside the bubble, but the laser beam inside the bubble is perfectly coherent.

[@pencrows]

The dude who made the original video of the bubble bouncing off the laser beam really should have been wearing eye protection and the laser beam actually swiped across his face momentarily just showing how close he gotten from becoming permanently blinded.

[@GlorifiedGremlin]

Imagine not wearing your glasses and you have to tell people you were blinded by a bubble

[@yuxin7440]

My speculation regarding the bouncing effect toward the end is that there is a very thin colorless wire (like fishing line) connected to the laser to the wall, and it's actually the line that bounce the bubble. This is because the position that they are pointing the laser at seem to be a fixed position on the wall, which is where the wire is mounted. There are some weird glaring effect when they move it around even without hitting the bubble (around 10:33), which is the effect of laser diffracting though the transparent wire (while dust can have similar effect, it just seems a bit unnatural). By the way, I haven't watch the other video yet, and this is only my speculation.

Here's one thing I discovered. If I shine a very bright flashlight (in my case, a Rovyvon Aurora A3) onto a piece of aluminum foil, I would hear a faint humming sound. I tried wrapping the aluminum foil around a piece of metal, then putting it over a flame to deposit a very thin layer of soot, essentially making poor man's VantaBlack. This made the humming significantly louder. The humming would only appear with the flashlight in the low or medium brightness settings, since at full brightness the LED is lit 100% of the time, but a lower brightness levels the led is illuminated using pulse width modulation

So, you can definitely bounce a laser off a bubble. Good to know.

2:52 “ever see a bit of bubble bounce” say that 10 times fast 😂

The funniest part is the laser guy going "Oh my god it is *terrifying* don't try this at home" and it's just reflecting LOL like he's the only one that really *really* knows how powerful that 11W laser really is.

Rather uninteresting as far as your body parts go. Your eyes, on the other hand...

9:09 The moment when you want to test a mystery and create another one :D

[@valshaped]

My first thought seeing the video is "Where in hell is his eye protection?" not so much "Oh, it's fake."

9:09 You invented the laser-bubble disco ball!

Do you remember that laser twezers thing? Whoever made this did research a bit. Lasers can actually be used to lift and levitate microscopical diamond spheres, and they even move towards the laser source!
