No. You visit the cryo lab in the Engineering building and decant a styrofoam cup of liquid N2. And toss it in their general direction.
If you do not encounter anyone to slather with the chill, carry it back to your dorm room and freeze one of your room-mate's textbooks while he is reading it.
Then watch the page crack.. ;-)
Any resemblance to any real-life events that may or may not have occurred is purely noncoincidental. Of course, in the walk from the Engineering building to the dorm, more than half the contents of the styrofoam cup (might have) vanished into thin air if this were a true recounting of events. A styrofoam cup is an imperfect emulation of a cryobottle... ;-)
Golly, I’ll bet you were popular with your roommates.
These days, you might have to chill some dudes iPad.
An iPad in Liquid N2.....
Hmmm...
That sounds like fun.
