Why would a person want to mess around with that stuff anyway? It absolutely makes no sense to me. Isn't it easier to buy it in the supermarket, or get an ice cream machine and use the ice cream salt they sell for ice cream makers?

Thx.

I actually built rockets for 19 years. What Alton did is very dangerous. Liquid nitrogen can frost burn the cornea in your eye & result in blindness. Also, enough of it in your room & it will displace the oxygen (O2) and you will suffocate. Never do this, buy an ice cream machine....Al-

And what was the purpose for all of this, shown on TV? for copycat's? Now I know why we are number 26th in the world, smart....NO.....dumb and dumber....yes

LMAO!!! "Lick it!!" This was crazy funny.

you can also use dry ice. put bowl of ice cream mixture in a larger bowl with crushed dry ice and water.this will set up in a few minutes.

Wow, that was sure exciting.

I thought liquid nitrogen would cause frost bite . It gets real cold when released into atmospheric pressure as it boils to a vapor. I suppose it could be deadly if released in a confined space and depletes the oxygen.

Liquid Nitrogen can be used safely as shown in the video, but it CAN also be very dangerous if you're in contact with it for several seconds. It's like dry ice -- if you handle it quickly, you're fine. But if you touch dry ice for more than 12 seconds, you'll start to get frostbite. Likewise, if you transfer liquid nitrogen into a non-insulated container and hold it for few seconds, your hand will start to freeze. I'm speaking from personal experience -- it can be very painful. So if you're going to use it, be sure to keep it in the insulated dewer it comes in.

How is LN2 potentially deadly using it like that? The media needs to stop trying scare the $#!T out of the American public daily.

I've seen this done at our local children's museum. The kids loved it and eating the ice cream, lol. Funny how adults can be fascinated same as the kids but cautious enough to miss out on the whole experience.
