Winner of a Parents’ Choice award, this is the lab set that teaches the scientific principles of cosmetics as young chemists concoct soaps and bath bombs. The 35-piece lab provides all the tools and ingredients needed to create colorful molded soaps, scented oils, botanical soaps, and fizzing bath bombs. As aspiring soapmakers conduct experiments, they learn how different additives affect the color, smell, and other qualities of the products they make, how acids and bases combine to form fizzing reactions, how to measure pH levels, and the chemical properties of soap that help it wash away dirt. All materials and chemicals are non-toxic. Ages 6 and up. Box 8 1/2 " H x 11 1/2" W x 3 1/4" D. (1 1/2 lbs.)
