Screaming Dry Ice

A quick video on how to how to annoy people working in your lab with dry ice. The noise comes from when the dry ice is heated up by the metal it sublimates and the gas being created pushes the metal down briefly. The resulting vibration results in the screaming noise.

Now we need another video showing why this works.

[powerm1985]

@macman393 The explanation is in the crotch bar and more awesome cold based science is coming soon. In fact this was just a little extra footage that did not make the final cut on a vid about liquid nitrogen.

[tommylehman]

Fuck, that hurts my ears this listening to it on youtube. 

[powerm1985]

@tommylehman IRL it is much worse

[Answersinbooks]

Better plan: When they are not looking drop some into their rotary evaporator bath. Then watch the panic :)

[powerm1985]

@Answersinbooks I do that all the time but only to make my work look more "sciencey"

[IslamFox1]

YOUR AMAZING !!

I'M REALY ENJOYING WHAT DO !! :D

School Nuff said

[1234doawee]

can you please do a video debunking hulda clarks "zapper" please? :) (in case you didnt know she wrote the books "a cure for all dieases", "a cure for cancer" and "a cure for hiv/aids. THANKS!

[ConradW]

you're hurting it!

@powerm1985 Are you going to do one on lyophilization? I always thought that was pretty fun (and a handy thing for keeping samples for a long time). Or critical point drying? Amusing tricks with triple point diagrams usually raises a few eyebrows from the people who don't think about it much.

[salerio61]

@sarcleaeolist roflma now THAT just has to be done :)

@Answersinbooks ahh prank wars in the lab.. brings back fond memories.. I once set up the old water ballon and pin trick on a doorway so that the ballon bursts all over the person entering the room. except it was filled with 2% gentain violet soln.. and the 1st person through the door was a visiting professor.. opps

[Leonis1989]

Or get a chunk the size of a brick and throw it at them.

[mrdaym]

But seriously though, explain the science in another video. I know I could easily look it up myself but that's hardly entertainment.

I work in a chemistry lab, and sometimes when I'm bored and waiting for a reaction to run, I'll press some dry ice against the TLC heating plate, producing this awful high-pitched squeal. Dry ice is also good for a makeshift game of air hockey with a lab mate. Ah, the things we do to amuse ourselves in lab...
