Here is a bit more on the safety precautions in this experiment:
Regarding laser safety…This laser was run at just above its threshold current, putting it at 5mW of output power according to my own measurements on an OPHIR laser power meter. At 5mW, this laser is classified as FDA “eye safe” meaning that the blink reflex will prevent any damage from this laser, even from a direct hit. I ALWAYS wear laser goggles when working with lasers over 5mW!!
StyroPyro also replies to one of the safety skeptics on the thread:

We hope you enjoy this science awesomeness!

Ummm did the movie Real Genius happen?!?!
Quantum Mechanics in action, Baby!
Gears of war Imulsion lol
People haven’t done or seen this yet? Pretty sure they covered this in 1985, the movie was “real genius”. Granted, its funny to watch now, the power outputs..
Things don’t get dicey. The cold of the liquid nitrogen changes the light wave of the Lazer and hence changes the color from red to yellowish. There is also a guy in the video that is way to excited about this….your welcome.
