Thousands of dentists around the country have teamed with "Operation Gratitude" to turn Halloween candy into cash. Tadpoles donate their candy to dentists, who'll pay them $1 per lb. The kids walk away with extra spending money, and less likely to get a cavity. Then the dentists turn around, and with the help of "Operation Gratitude", ship that candy overseas in care packages to our fighting forces of the U.S. military. Last year, the group collected over 125 tons of Halloween candy. How cool is that?
