Squealing Dry Ice

[AndromedaChao2]

The sounds dry ice makes when you cut or compress it would make great sound effects. It can even sound like an electronic screw driver when you compress it.

I was watching with headphones full blast

@alaahdino Bummer. Sorry about that.

@alaahdino XD

sounds like the worst opera EVER!!!!!

I remember way back in 7th grade when we were using dry ice in a lab and everyone in my group freaked out when the metal tongs touch our chunk of dry ice.

[MrMontez11]

"The dry ice symphony"?... that could go places :)

[161803]

haha it's like slaughtering piglets!

[JeffersonLab]

@161803 Or at least scaring them really badly.

[Zizumia3]

hmm. sounds like a sound trick that disney would use in the 1930's to resemble scrathing a black board

[mamonsin]

lol at the end

[FlumenSanctiViti]

Would we get the same effect by placing a red hot metal rod on a regular (water) ice?

[JeffersonLab]

If the iron were hot enough to melt the ice and then rapidly boil the water, it would do something similar. The problem with that is that it requires a lot of energy for water to go through two phase transitions as well as bring water from its freezing point to its boiling point. The dry ice has an advantage since it's going directly from a solid to a gas.

@JeffersonLab soooo, something like thermite on ice would do this, only you wouldn't hear anything, other then the super burn from the thermite itself. thermite vs Liquid Nirrogen/dry ice.. think we all know, who wins that one. The approximate temperature in which thermite burns is 2500 degrees Celsius, or 4532 Fahrenheit ....(replays 1 year later) ;)

If you were to touch a piece of dry ice, first thing you will notice is the block of dry ice will stick to your hand, which can be explained by the water vapour on the surface of your tissue freezing. In five seconds you can feel the pain, in 1min you will suffer froze bite.

[kingbrooks1000]

what happens wen a person touches dry ice?

[JeffersonLab]

It depends on how long the person touches it. If it's quick, nothing much will happen. If it stays in contact with them, it'll eventually freeze the tissue it's in contact with. Of course, the problem is knowing how long is too long. That's why it's best to wear gloves.

[TheMetalhead01]

can you have liquid co2

[JeffersonLab]

Yes, but not under standard atmospheric pressure. If you place carbon dioxide gas under enough pressure, you can force it to a liquid.

[TheMetalhead01]

can you have soid nitrogen if you can have solid co2

[JeffersonLab]

Yes, you just have to get the liquid nitrogen a little bit colder. Liquid nitrogen, under 1 atmosphere of pressure, boils at 77 Kelvin. Cooling it to 63 Kelvin will freeze it. It doesn't have a very wide liquid range.

[supersonicstep]

so thats how dry ice looks like

[craz3ykiller]

SWEET!

[singinguntildeath17]

when u did the flashlite the 1st time, it sounded like a car stopping

[firebert123]

oh man, that's ridiculous... love it!

[tutorialconr]

I love your videos
