This brings back fond memories of our first chemistry set, and how nice the firemen were after our first experiment went horribly wrong. But don't worry, this kit is easy. Just assemble the mold, add the powdered polymer and submerge it in water. In just four minutes, your ball is ready -- simply detach the mold and start bouncing. Get creative and mix the colors to make your own custom designs. Each kit includes an assortment of colors and makes two balls; each 1 1/4" in diameter. Detailed instructions included. Choking hazard: not for children under 3.
