So the $99 question is where can you buy liquid Nitrogen?

So the $99 question is where can you buy liquid Nitrogen?

My 99¢ question is do you really care or are you being silly? I was silly and Googled it.

Airgas.com offers it. The smallest container I could find (in 2 minutes of research) is 160 liters. The page said to enter my zip code or sign into my account for price and availability. I put in my zip code and got a red letter reply that basically said "we aren't touching this with a 10 ft pole. You have to talk to real people before we will give you any more info.

On another site it was suggested the price is somewhere between $0.50 and $2.00 USD per liter.

I have seen some machining videos where they soak a part in liquid nitrogen to get it to shrink to provide a tighter than press fit fit (when the other part is way too big to thoroughly heat.)

I was just wondering if it could be bought. I know they fill car tires with Nitrogen for temperature stability and to keep the rims from rusting. My Mini-Cooper came with it in the tires, but when I had the tires replaced they wanted to charge me $5-10 per tire to refill it with Nitrogen.

This doesn't seem much different than the rockets we used to launch with water and an air pump.

High pressure forces water out through a nozzle - Newton's third law and off she goes.

The high pressure comes form either the pump or the evaporating liquid nitrogen. (perhaps there is additional pressure from the carbon dioxide in the coke, but I doubt that amounts too much.

Yet another Darwin Award entrant in the making.

So what went up from his hands if the bottle is on the ground near him? In slow-mo it looks like the bottle takes off out of the frame at a high rate of speed. There doesn't appear to be anything that goes out or down from his hands?
