Interesting that the canned duster works for that. I've heard of people using dry ice to pull out door dings. I wonder if an upside duster can could work for that, too.

gotta love thermodynamics. a phase change is always the best way to move heat. it's how air conditioners work. it's also why a steam burn is so much worse than a liquid burn. when you flip the duster can upside down, the liquid layer rather than the gas layer comes out of the nozzle. when it turns to gas, it sucks the heat out of whatever it came into contact with.
incidentally, you can remove warts with this stuff. flip the can upside down, spray a q-tip for 10 seconds, and put the q-tip on the wart for 10 seconds. repeat once. no more wart, & no visit to the doc.
