Seed bombs

 Seed bombs give life to gray city sidewalks. You can make them too. Take quality seed, soak over night, use clay type soil for plants, shape balls, put seed inside and leave balls to dry 24 hours.

 Gumball machines that dispense "seed bombs" of native plant seedlings, which you can throw on the ground and (temporary) bring life to the urban environment. Just throw them into sidewalk cracks, vacant lots and parking medians.
