That's.. kinda cold.
I'm going to have more than 20 litres of liquid nitrogen on hand at my party on Friday.
I'm looking for ideas for things to do with it.
* Make icecream
* Freeze things and smash them
* deflate balloons
* freeze alcohol - boozesicles and alcoholic ice!
* self-propelled spinning pingpong balls.
* bubble machine
Anybody have any other bright ideas?
(I wanted to get liquid Oxygen, but they only sell it in 180L quantities. Then I wanted to get liquid Helium, but 30L is $457.71. Le sigh.)
