I remember cap guns. I bought my boys them years ago and the smell really brought back memories.

Ah, cap guns. I burned many a roll of paper caps in various cap guns when I was a kid. You could also pop the caps with your thumbnail, even more fun when one would ignite when lodged under the nail. Or you could just smash a whole roll (or more) on the sidewalk with a hammer.
