Morning all!
VC- hopefully your chemistry teacher isn't as harsh as mine. He was once doing an experiment with liquid nitrogen, and after smashing a frozen banana, one pupil asked what it would be like if a finger was to be frozen.

So, the teacher bungs on a leather glove, and proceeds to stick one of the fingers into the liquid nitrogen, until it is frozen. And then promptly smashes it with a hammer.

Everyone screamed, five vomited, three fainted.

Turned out he'd just filled the middle finger with sausage meat.
