This looks like a whole lot of addictive fun. The Japanese Popping Edamame Keychain ($9.99 from ThinkGeek) contains three beans, the middle bean having one of 12 random faces printed on it. Furthermore, the beans are connected to some sort of elastic band, so they pop back in to be popped again as many times as you want. What more could anyone want from a keychain?
