When dry peel the stickers off. The color on the inside should be revealed in the shape of a star. We put votive candles on the inside of our baby jars and made our own 4th of July light. It looks almost like stained glass and is non-flammable. Have children choose any small or medium size container to use as a Jell-O mold.
Bowls work well, but the more interesting the better.
Once the Jell-O sets well, remove from the mold and place upside down on plate or work surface. Repeat around the mold until the desired 3-D fireworks production is complete. Make one bowl red, and one blue. Have the children dip bubble blowing sticks in the bowls and they will blow the blue and red bubbles on a white sheet of paper. It looks neat to see all different creations.
