Brought to you by Kieran Mullen, University of Oklahoma physics professor. Actually, this video was only a gratuitous demo (but an effective one at that) . While we're on the subject, there are many things that can be destroyed after a bath in liquid nitrogen and an encounter with the floor: pumpkins, locks, and of course, giant koosh balls .
 the same principle goes for cell phones and full-course meals. You know who you are.
