Cut the construction paper into 1-2 inch squares, and sort them by color.
Add each color of cut up construction paper to a small bowl and add water until it covers the paper.
Allow paper to soak for 30 minutes.
Remove the paper from the water, and wring it out slightly. Dump water from bowls.
Add one color at a time to the food processor, and pulse until it’s finely shredded.
Add each color paper into its bowl, and add a half package of flower seeds. Mix it all together.
Gather half of each color mixture and add to one of the heart mold cavities, pressing down to fill the mold.
Allow to set for about 48 hours.
Gently remove from mold. If not completely dry, air dry for an additional 24 hours.
Plant the seed bombs into flower pots, or into the ground.
