• Birdseed or lawn seed
• Natural sponge
• Ribbon or cord
• Shallow pan of water
Buy a natural sponge from a drug store or health store. Make a small hole through the center and thread the ribbon or cord through it. Tie a good knot at one end of the cord. Wet the sponge and sprinkle the seed over it and into the air holes. Hang the sponge in a sunny window with the tip of it resting in a shallow pan of water. Seeds will sprout so long as your child keeps water in the pan.
