I held dry ice before, its only intense cold, which unless you keep it on your skin for a while I can see it doing that. =l But I never had problems holding it for a short amount.
yes it was genius. it doesnt cool your hand down the second you touch it. it takes a few seconds. and my dads a physicist and i did this at a physics demo. I know what im talking about.
You were lied to then, your dad and yourself knows nothing about dry ice, I've touched it for less than a second and got a first degree burn, if you hop it from hand to hand, it just means your hands will be hella burned...
you are completely wrong dude. the fact that it has to be so cold to be frozen, means that it actually boils at room temperature.. hence why its in gas form in its normal state. So by touching it your body, which is warmer than room temperature, it will still boil. If you leave it on the same spot for very long, it will drop the local temperature of your skin to severe cold temps and cause serious damage. I work for a company that design particle accelerators and we use liquid helium..which is even colder. (only thing still in liquid form at the coldest temperatures humans can reach) I touched that and it boiled before it touched me, because of the temperature difference, but hold it there... bye skin
OK, I'm simply saying it's conceivably possible to juggle it, but you would have to move faster than I have ever seen a person move before... I've learned from experience not to touch it at all, and I'm just trying to make sure people don't convince people to do something stupid like hold dry ice without protection...
i have a feeling this won't work too well... it depends on how tight the paint can's lid is, and if the paint freezes before it blows or not. but maybe put the paint in a 2 liter bottle
The reason why you can hold dry ice for a second or so is called the Frost-Bern effect? (I think thats what it is called...) When you touch the dry ice, it quickly turns to a gas, protecting your hands from the cold for a short period of time..... This also works for liquid nitrogen and molten lead, but for the lead you need to soak your hands in water first....
that is not a picture of a guy putting dry ice on his forehead, first off, all it would do is leave frostbite on his forehead, and second, you can easily see the circular pattern of the blunt force trama that caused the bleeding
