Folks with itchy fingers who need to keep them occupied while performing other tasks such as going through a list of numbers or talking to somebody over the phone will definitely find the Japanese Popping Edamame Keychain to be a boon.

Each Japanese Popping Edamame Keychain has three beans. The end beans are small and immature. The middle bean, however, has one of 12 random faces printed on it. Why? We don’t know, but there is nothing like the smile it puts on your face. And 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. It sounds silly, but trust us, these things are highly addictive. They are also a great way to keep your fingers busy during boring meetings and your mood positive – because no one can frown when their edamame smiles.

ThinkGeek is currently selling these pointless yet fun keychains for $8.99 each.
