Pennies. Me and a friend I went to high school with were having one of those dumb conversations that you have once you have a couple of beers under your belt about how pennies cost more than their value and he said just about the most interesting thing. Pennies are made of both copper and zinc (which are naturally antibiotic) and if you put them in your shoes between wearing them they will kill off stink producing bacteria. He majored in chemistry so I thought I'd at least give it a try. I only had about six pennies but I threw three in each of my work boots and wouldn't you know it, it worked.
