woo Leidenfrost effect!
I learned about this just before xmas at a warwick uni xmas physics lecture thingy. The Leidenfrost Effect means you can quickly dip you hand int a vat of liquid nitrogen without it freezing. basically the massive difference in temperature means there is an insulating layer of gas between the hot object and the cold object (which is easily visible in he video above), first time i'e actualy seen it visibly though.
