Seriously, what the fuck?
the teacher didn't even do anything
What sort of sick fuck makes kids hold something that's -56 without any protection?
You'd just drop it.
It's character building. Back in the day we washed our hands with liquid nitrogen.
Fire the teacher.
I remember when I my dad would sometimes bring home boxes of dry-ice for me to play with.
I always used a spoon or gloves to pick that stuff up, but one day I was like "Why the fuck don't I just grab it?" and I grabbed an entire hand full.
After that I couldn't use my entire right hand for a few weeks.
I was such a special little child.
When I handled dry ice back in middle school I willingly did it without gloves.
I got 50 cents for licking it too, bought a cookie at lunch with it.
I love dry ice.

I'll make it clear that when I held the dry ice, it was a small chunk that we had to place into a little cup which we then poured water on. Also when I licked it it was barely even a second, it was back in middle school so no one really cared about how long, just if it was done at all. Still, I ended up with a cookie so I don't give a damn about anything else.
fucking teacher give it the death penalty
Retarded teacher, good riddance.

No something worse...
DRY ICE TO THE NIPPLES

How?
Do you have asbestos hands/tongue or something?
I think a freeze burn is the only kind I haven't had happen to me.
I would've slammed it into the teachers' face.
They should have eaten it.

It's actually completely possible to hold liquid nitrogen in your hands with no adverse effects.
Or so I recall...
Fuck, those blisters look terrible.

Suppose it would evaporate pretty quickly.
Still absorbs heat from the surroundings though, so I imagine you'd still get pretty horrific blisters.
Fat sack of shit should be fired. How does someone like that even get to be a teacher?
You can hold dry ice you just need to have very clean hands. Same principal as Mythbusters and the molten lead.
Ummm crazy idea. If it was hurting your hand, why don't you just drop it?
[QUOTE=Diagger;35024677]You can hold dry ice you just need to have very clean hands. Same principal as Mythbusters and the molten lead.[/QUOTE]
not even, just pass it between your hands semi-constantly, its nowhere near as cold as liquid nitrogen.

Actually, this is different, the reason behind the putting your finger in molten lead works, is because they wet their fingers and dipped it in, flash boiling the water on their fingers, making a little bit of steam that isn't really all that heat conductive. This is a solid chunk of frozen Co2 which sublimes constantly, and the Co2 coming from it is always near the same temperature as the dry ice.
Fire him by all means, but I can't help thinking this is going to impact the school more then the teacher.
Still I blame the kids for holding it for longer then half a second, I mean it's fucking -70 or something, why wouldn't you just [B][I]DROP IT.[/I][/B]
if the power of authority can make someone administer fatal electric shocks to someone else then there's no reason it can't make schoolchildren hold dry ice

It isn't I did it in Chemistry class with my professor.
I do think this is partly because of the students as well, considering that they willingly held it for so long, it's not like the teacher made them hold it for that long. And even if he did, they can just drop it, and leave the classroom and tell the administration about the teacher making them hold pieces of hazardously cold ice without proper protection. A side note here, why the hell were they playing with dry ice anyways? At my school in missouri, the school is so scared to death that they won't do anything with dry ice or liquid nitrogen, hell, i had a little tiny vial of mercury i wanted to show my teacher and she flipped the fuck out, told me about the fancy cleanup procedure if i spilled any, and i was suspended for having it, and the confiscated it and gave it to the police.

If you had really clean hands prior to handling an extremely cold substance, that actually would cause heat conduction to occur faster because human flesh conducts heat pretty well. And the trick to holding dry ice for extended periods of time without gloves is to keep it constantly moving so you don't get frostbitten.
After multiple attemps on making dry ice, I decided that that this news is fake, and that dry ice doesn't even exist. I've tried putting ice cubes in the microwave, letting them sit on the sun, tried the oven, the stove, even tried big gold melting ovens.
Its always wet :(

The principle with the mythbusters molten lead experiment was that you could dip your hand in it for a fraction of a second if your hand was wet, which is possible, but completely different than holding dry ice without gloves for a minute.
Dry ice is CO[sub]2[/sub] gas in a solid state (iirc), so naturally it's extremely cold. I'd imagine that if you held dry ice without gloves and your hands were wet, it'd just freeze to your hands.
