no more boring stuff at home, here`s a new game -
fun with liquid nitrogen:

Freeze a can of shaving cream and then peel the can away from the cream. Put the canless cream into someone's car. Let the oven-like heat from the car's sitting in the sun defrost the shaving cream. 2 cans will fill an entire car. (Coulter C. Henry, Jr.)
