Nitrogen condenses at its boiling point , -195°c to a colorless and odorless liquid that is lighter than water.

Could you show the same thing in a a live video stream on a certain time?
I’d really like to see it. I myself usually use ustream or http://www.tvmad.com maybe they’lle help ya.
If yould be willing to do it then let me know, I’d be 100% there to watch it.

Cheers

I’ve done lots of fun things with liquid nitrogen as a high school science teacher. I’ve dipped my hand in. I’ve done the “drinking” thing (as pointed out by Aaron). But the kids get the biggest kick when I take a graham cracker, dip it in for a few seconds, then eat it, with LN2 “fumes” coming out my nose. Then there’s the “freeze the goldfish and bring it back to life” bit that gets lots of attention.

If you’re on Facebook, you can check out some of the liquid nitrogen videos in the “Mr. Becke’s Physics Classroom” group (not all featuring me). (and also see me in a faraday cage at the Singapore science museum, getting shocked by a giant Tesla coil)

I guess if you don’t speak German you might miss the irony of the name “Leidenfrost.” It’s not actually a word, but “Leiden” means “suffer” and “frost” means “freeze.”

I preform demonstrations with liquid nitrogen for the physics department at the University of Cincinnati. After freezing and shattering balloons, roses, etc. I always stick my hand in just to shock the audience.

However, I have not yet tried this: http://www.youtube.com/watch?v=R2f1ECjs9fA&NR=1

I can intellectually agree all I want. My hand won’t get damaged, it’s the Leidenfrost effect. My emotional brain wouldn’t let me put my hand in no-how!
