Make the world a little greener by depositing seed "bombs" in forgotten outdoor spaces. Using fun shape molds, you can cast seed bombs from fast-growing flower seeds, growing medium, plaster gypsum, sand, and water. Once the seed bomb shapes have dried and hardened, they can be distributed in appropriate outdoor places. After a while, a beautiful cluster of flowers will explode in those spots.
