I didn't do it
Chthonic wants to know about awful, terrible things you have definitely never done. But secretly have. Confess!

it really doesn't work.
I've tried it with liquid oxygen and liquid nitrogen and rubber hoses.
Science regularly gives itself a good talking to, and then we go out and make fluorescent cats. It's all about the LOLZ.

Takes a bit of time.
But we freeze rubber tubing and fruit for 1st-year demonstrations, usually ending in smashing them with hammers.

Yeah, you're right - it works if you dip them in it for ages
it doesn't if you pour it on, because the constant vapourisation at the surface means a layer of gas between the tube and the liquid for the duration and vapour is a rubbish conductor. I've poured the stuff onto my bare hand before for the same reason. Although I wouldn't recommend it, kids.

Good tricks with LN2
#341: Fill a foam polystyrene bucket with the stuff, drop a rubber bung in and then reach in and pick it out with your bare hand. Note: long arm hairs can penetrate the vapour barrier, let the liquid through and sting like hell.

Since my research group is more biology than anything else these days
it's the dry ice for the pranks. You'd have thought, with my supposed maturity and seniority, I'd have stopped putting dry ice in other people's tea, wouldn't you?

I read this as 'rubber horses'
I want to dip a rubber horse in LN2 now.
Edit: Or oxygen, or helium...
