Neat video, but this laser (approx. 30-50 mW) will never be capable of boiling water as it is shown here. You need multiple watts of power such as 10-100+ W focussed to a small point of lets say 500 µm or less to see an effect. And then it wouldn't be that global but more locally fixed.
requires 4J of energy to heat 1 gram of water by 1 degree Celsius. I am guessing if that is water (probably not) there would be bout 50 grams. if he started at room tempurature 20 celsius it would take 80 more to bring it to a boiling point. 80x50x4 brings us to 16,000J or 16Kj of energy required to heat "water" to boiling point. so lets see he is using like a 200mw laster that would probably mean the battery on the laser would die before he could boil the water.

this isnt water (bit too liquid), maybe ethanol or ether. and youve put some vacuum on the flask to bring down the boiling point to room temperature ^^
What I think is the most interesting part of this is that the bubbles actually start to form on the coal which tends to make you believe it's heating the "water". You can also see some turbulence in the bottle caused by air leaking passed the stopper before the vacuum seats it well. A friend of mine also figured something was up because I chose to shoot the laser through the side of the flask, losing energy, rather than through what should have been an open top.

@aVoNgfx you can boil coffee with around 1w. Probably less.

Can this be done without the coal?
VizardJinchuriki 1 year ago
@VizardJinchuriki Yes. Neither the coal or the laser have anything to do with the "water" boiling.

I don't see the top of the flask which leads me to believe that you pulled a vacuum on the flask
causing the water to boil.=D The max output that laser is capable of like 175mW's will NOT
cause the water to boil. BS

Actually, wicked lasers has hand held lasers at 400mw. I highly doubt this guy did this though, because
A: they cost $5,000
B: Even at 400mw, this would take much more time
C: All of the below/above comments.

@Dms12444
Even at 400mw that's not even half a watt... You can't boil water that fast with that kind of energy output.
Plur307 2 years ago
I did say that, in fact with that output it is doubtful that this would occur within any short length of time.

Wicked Lasers has lasers at 400mw, I still highly doubt this though as
A: they cost $5000
B: Even at 400mw this should take much longer

nice trick tho :)

in fact at 0:22 you see the bottle move and pressed towards the bottom as you plug the thing (i know the word in german - scuse me ^^) in ;)

The laser in the video is a Phoenix but I should point out this is related to fun as well as to Science & Technology.
