Liquid nitrogen + 1500 ping pong balls

What happens when you take a scientist, liquid nitrogen and 1500 table tennis balls?

I could swear I've seen a hardware-accelerated physics demo on the XBox that did this, but with more particles, I mean ping-pong balls.

The title should have read, "3.5 Minutes of Nothing + Liquid nitrogen + 1500 ping pong balls"

Shut up you outspoken A.D.D. science hating tool bag!


Nice self shout down

And yeah, I quite enjoyed the introduction and explanation. Even though the science of it is pretty simple and I already understood how it was going to work, his manner made it fun to watch.

He had the gloves right there on the table--but forgot to use them.
An F for safety.

"For our next demonstration we'll see the effects of liquid nitrogen (−196 °C; 77 K; −321 °F) on human skin."

Did anyone else expect the ping pong balls to go up in the air and shatter when they hit the floor? I think that would've been really cool.

Gloves are more dangerous than bare hands when pouring.
When handling in a bath, yeah, gloves....but not when pouring. Leiden-frost effect makes sure your hands stay toasty warm.
