university town and that's where I got my dry ice for popping
dents out of my car. You just hold the dry ice against the
dent, rubbing it in a circle until the dent and the
surrounding area frosts over, Then let the sun do the rest.
Or you can put a hair drier on it to speed the process.

there's an easier way. just buy a can of compressed air (for computers) and turn it upside-down and start spraying the propellant at the dent, and it'll frost over just as fast. plus, you don't have to steal compressed air.
i dunno. i work in a research lab with a huge box of dry ice at the door, and i still think it'd be difficult to just steal a piece and transport it across town to a bike rack. i can't even imagine doing that with liquid nitrogen, and trying to transport a sloshing liquid o' death about a mile and a half across campus.
