Liquid Nitrogen and Pool Party Don’t Mix [Video]

A group of what looks like college students dump huge amounts of liquid nitrogen into a pool and tell everybody to "Jump in!". Seems safe enough right?

I mean the only time I've every heard of someone using liquid was for three simple reasons, experiments, killing people, and destroying the T1000.  

7 people fainted and one 21 year old is in a coma. Yay pool party!
