This is a video of Plymouth University professor Roy Lowry placing a bottle of sealed liquid nitrogen in a trashcan, then covering the bottle with 1,500 ping-pong balls. What happens next? Nothing I ever got to witness in any of my lame-ass science classes, I can tell you that. Although one time a professor did break audible wind during a test and told us he'd give us all A's if we promised not to write about it on social media. I LIED HARD.
Hit the jump, but skip to 3:30 unless you actually want to learn something.
Thanks to Smurf, who once had his/her mushroom house destroyed when it rained ping pong balls.
