Great find. Can I nominate more than three names for a Liquid Nitrogen challenge ? (Assuming I'll trick them first by using dry ice also ?)

Looks like he was demonstrating that the temperature of liquid nitrogen (°C or °F) and his IQ are the same.

Well he's not hurt due to something called Leidenfrost effect[^]. I heard it for the first time, though I watched Mythbusters episode where they did demonstrate effect it with molten lead. So I wouldn't call that guy stupid Smile | :)

Quote from wiki:
Canadian chemist Moe Qureshi performed the ALS Ice Bucket Challenge using liquid nitrogen instead of ice-water

I wonder if Qureshi is equivalent to Howard? I still say the guys a fool.

In my past life, I used more Liquid Nitrogen then milk (by far). You can get away with some kinds of contacts, via the Leidenfrost effect, certainly. It happened frequently enough. It was used without the least fear or trepidation. And used for a few jokes, too (splashing a bunch on a men's room floor whilst some is sitting upon the thrown).

But should the LN₂ linger another second or two, such as a fold in the skin, inside an ear canal, etc., it will cause nasty frostbite very quickly - and kill the skin (much like a 2^nd degree burn) very soon after.

The guy really is quite the jerk.

The Leidenfrost effect would only serve to preserve the temperature of the nitrogen, allowing it to do more damage, if left in contact with his (presumably) warmer head -- which it was.

That isn't LIN. - first it'd need to be kept in a proper ~~thermos~~ dewer flask to stand any chance of not boiling off immediately. Enough liquid in the metal cotainer he had to not have boiled would have made the container so cold solid CO₂ would have condensed out he atmosphere and picking it up would have frozen the sweat on his hands solid - fusing them to container.

Had he poured liquid nitrogen on his head, his hair would have acted as wicks drawing it down and basically freezing the skin off his scalp. Additionally wiping it off would have shattered his hair.

Finally the "steam" would pour downwards as the the cooled air would be denser than that surrounding it - but that could be wind + the image is pretty hard to see.

My guess is he had solid carbon dioxide in there.

Original video[^]

And another cool video demonstrating Leidenfrost effect[^]

I've seen the the Leidenfrost effect first hand - demoed on the palm of someone's hand. When we where working with high vacuums and needed a cold trap.

The problem with the video is the fact he's pouring it on his hair - this as I said, acts as a wick, which is the same reason why you don't use the back of your hand to demo for "extended"contact, though you can very dip your hand in the stuff very briefly.

I still don't believe the video - it looks like quite a lot hits the ground, this would freeze his feet, plus any trapped under his shirt would definitely freeze him.

I'm pretty sure it's fake too (LN2 in hair and clothing is an Oh Elephant Me! moment); but from watching people use it to make icecream I'm pretty sure there's a bit of time between the bucket being cool enough not to immediately boil off on the inside and being cold enough to freeze your hands onto the outside. And if your hands are dry you can briefly handle dry ice without them freezing to it.

So regular viewers may remember that my Company was bought by Seagate awhile back. The actual official change-over will happen on the 15th September. I know this because I've just been handed my Seagate Boarding Pass, complete with Boarding time, date etc.

Lucky really, as being an American Company I thought they might try to do something Cheesey instead.
