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.)
Are you trying to get me in trouble? I live in a research university town, so liquid nitrogen is very easy for me to get, and I don’t need any more evil ideas. 😛
When I was working on activated carbons back at U of I, I discovered one day that LN2 makes a very effective insecticide. Just a li’l splash does the trick on even the largest roach.
I actually know someone who did this when I was in high school.. We did a lot of pranks there. A groups of friends and I seran wrapped and taped (not electrical.. the thick grey tape) a car. The seran wrap makes it so the tape doesnt actually touch the car anywhere, so it’s very safe actually to do. With a scissors it all comes off like a giant shell of the car.
Hehe.. I remember the police were laughing about it afterwards and mentioned how they thought it was so funny another time when they saw people whipping balony (or was it salami? some round flat meat) at cars. Note.. don’t try it.. it’s worse than you think if you don’t know.
