Someday soon, you might just stumble upon one of the unusual vending machines shown above. But I wouldn't recommend chewing on the contents. Instead of gumballs, these machines dispense seed bombs. Pop in a quarter, and you'll receive a ball made of of clay, compost, and seeds. Toss it into any crack, crevice, or abandoned lot, and soon tiny plants will begin to sprout. Each seed bomb is guaranteed to make the world a little bit greener.
