Seed Bomb Vending Machine Answered
Seed bombs are little balls of clay, compost, and seeds that you can toss into a vacant lot to try and get some new plants to grow. It's a guerrilla gardening technique and you can see how to make one here. If you just want to pick one up and live in San Francisco you can now buy them from a vending machine. These were designed by Common Studio from LA and repurpose old gumball machines with the benefits going to Project H Design.
