This one is a bit weird, but aluminum foil can actually be used to help heal small burns. The general thought is that, as a conductor, foil works to disperse the heat in your body out into the air or into the foil itself. If you have a small burn, try covering it with foil and then leaving it covered from 15 to 20 minutes. After you take it off, there shouldn't be any pain from the burn.
Of course, if your burns are more serious then you should probably skip the foil and go to get treated by an actual doctor. However, this is a nice, cheap remedy for minor burns at home.
