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 2nd 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.

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.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

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.
