Reminds me of the time I used hair spray and a lighter as a blow torch and nearly burned down the woods in my backyard. Thanks for the nostalgia.

All I learned was that if you soaked snow with enough hairspray you could burn it. And that cologne could burn on your hand without hurting you.* *Don't try this at home.

    Feynman lived in Far Rockaway! I had no clue, I wonder if he lived near my current apartment.

  Rumor has it that hand sanitizer on a wet hand has similar properties, at least for short times.

    Yes. And a virtually incandescent flame. I too burned just about every household chemical I could get my hands on. I remember trying to light my name in fire on the concrete floor of our basement... Good times.

    ethanol burns relatively cool (as do (some of?) the other alcohols). the problem is that it often burns above the ignition point of its carrier substance, which itself burns much hotter. e.g. calcium acetate/isopropyl alcohol gel (lab sterno) is perfectly safe to burn in your hand, but only until the alcohol runs out--it will light the calcium acetate, which is not remotely safe to burn in your hand. hand sanitizer is usually an alcohol in water and a thickener (glycerin, etc.). i'd worry a bit about the same effect. (not that i actually know what the ignition and flame temps of glycerin are....)

This is an excellent method for lighting milk powder sprinkled through a sieve from, e.g. the top of a spiral staircase. Makes an impressive fireball.

Or a lighter and a can of wd-40 as a blow torch to kill flies. :D
