I worked at a hospital that would keep a record of lost fingers every 4th of July from fireworks accidents. It was always amazing how many people blow off a finger every year! There is a popular place in the areas south of Seattle, near Native American Reservations (they don't have the same laws on the rez so they sell illegal fireworks) to buy fireworks and within half a mile and 20 minutes apart two people blew their fingers off one year.
