"The surface you touch is considerably warmer than the dry ice and causes the dry ice to sublimate rapidly to CO2 gas. Since you're pressing the ice against the metal, there will be places where gas is momentarily trapped between the two surfaces, and when released through a small opening tends to whistle."

Best description I could find.

Nope. No sexual innuendo at all.


Damn, you beat me to it...

( especially 0:42-1:00, which makes "this is the part where the kids love it" really creepy)

Gee, a backpack with smoke pouring out of it. That would never get you tackled and your backpack blown up by a robot...

No, because for the most part german police still follow the credo to serve and protect


that's when they're not busy being total dicks :-)

gotta watch out for robots when you're handling dry ice. i learned that the hard way

"...can't touch it"
You can safely handle dry ice without gloves if you're not a moron and hold it in your hands for minutes.

and this is why your safety license has been revoked

moving on, i exclaimed, "that's awesome" out loud like 6 times watching this

I'm cornfused? If the water boiled away into water vapor under the vacuum, how did it end up back in the glass as ice when the vacuum was removed?


Not all of the water boiled off.

When they initially removed the pressure the liquid boiled rapidly because it's temperature was much higher than water's boiling point at that pressure (see the phase diagram linked above). The energy loss from the boiling dropped the temperature of the remaining liquid to it's new lower boiling phase-change point (notice the boiling slows significantly).

Since the pressure was too low for liquid water to exist, any water that hadn't escaped in the boiling instead solidified. From that point any vapor escaping would go directly from solid to gas (like dry ice does at normal pressures).

Icky Thump

Icky thump
Who'da thunk?
Sittin' drunk
On a wagon to Mexico

Ahh well, what a chump
Well my head
Got a bump
When I hit it on the radio

Red-head señorita
Lookin' dead
Came to said,
"Need a bed" en español

I said
"Gimme a drink a water,
I'm gonna 'sing around the collar'
And I don't need a microphone."


Icky thump,
With a lump in my throat
Grabbed my coat
And I was freaking
I was ready to go!

And I swear
Besides the hair
She had one white eye
One blank stare
Looking up,
Lying there

On the stand
Near her hand
Was a candy cane
Black rum, sugar cane
Dry ice and something strange

La la la la la la la
La la la la la la la

White Americans, what?
Nothing better to do?
Why don't you kick yourself out?
You're an immigrant too.

Who's using who?
What should we do?
Well you can't be a pimp
And a prostitute too

Icky thump, handcuffed to a bunk
Robbed blind
Looked around
And there was nobody else

Left alone
I hit myself with a stone
Went home
And learned how to clean up after myself

Nice post. Dry ice machines, which is what this is, are called "rumble pots" in the SFX business, because the dry ice and water make a rumbling when introduced to one another. The dry ice fog is heavy and rolls along the ground. The "fog machines" you use to create lighter ambient smoke or a lot of concentrated smoke actually vaporizes mineral oil to create that effect.
