They'd have to be pretty quick about it - neither acetone nor hydrogen

Acetone's not that volatile, as organic liquids go.

Well, no, but it is quite volatile as everyday liquids go. The more
volatile things tend not to stay around long enough to become everyday
items!

I used to have, ooh... minutes of fun with an open wide-mouthed acetone
container and a thin tube ducked into a container of liquid nitrogen.
The tube would spit out small droplets of LN2 which would then skate
around like billiard balls on the surface of the acetone, leaving little
vapour trails to mark their passage.

I'll have to try that.

The limit was my boredom level, not the disappearance of the acetone.

You were cooling the acetone with liquid nitrogen, though, weren't you?
