I am pretty sure surgical gloves do not count as safety equipment. It is a miracle this guy still has fingers.

But not from the exploding plastic. You need at least garden gloves for that. He's lucky it shattered from the bottom and not into his exposed eyes. That was supremely stupid to do.He'd be just fine due to the Leidenfrost effect. Google it.

You can't just pour LN2 in your hand, even though it vaporizes instantly.
You can! Try it! (seriously because the vapor cushion due to extreme difference in temperature it acts as insulation. After a while when your hand cools down this lessens and then you lose your hand.) It's like when you drop droplets of water on a hot stove and they skate around on it.

It has also been used in some potentially dangerous demonstrations, such as dipping a wet finger in molten lead[1] or blowing out a mouthful of liquid nitrogen, both enacted without injury to the demonstrator.[2] The latter is potentially lethal.[3]
... and you certainly can't dip your hand in it (as suggested by another poster).
You can pour a little LN2 onto your skin because of this, but you can't hold it in your hand and you certainly can't dip your hand in it (as suggested by another poster).
You can pour LN2 over your hand without any effect if you don't do it for too long. The "hot" skin forms a steam cusion kind of thing.
I'm assuming you're referring to me. Here's a video of Nathan Myhrvold doing this during a lecture at Harvard. He does this for the showmanship during basically every one of his presentations (they often make ice cream/sorbets for the audience). When he's done presentations on heat transfer in the past, he explains why he can't similarly stick his hand in a deep fryer. . . .

Yeah, he got it up to 9 digits before it shut down.Was he trying to overclock his hand??

Yeah, most guys play it safe and just use Vaseline.
yes, notice his splish-splashing
It's obvious you're grasping at straws now. You've been proven wrong. Accept it.
