This is a video demonstration of Kinetic Sand, a sand play toy made from 98% sand, and 2% Polydimethyl siloxane, a "silicon-based organic polymer...particularly known for its unusual rheological (or flow) properties."
Sand play stimulates and develops children's fine motor and creative playing skills. Kinetic Sand is the perfect material for open-ended, non-directed play. It leaves no sand or residue on your hands and is great for sensory therapy. Kinetic Sand is also great for kids with allergies - it is wheat, gluten and casein free and 100% safe and non-toxic. If you are worried because your child or pet has eaten some Kinetic Sand, do not fear, you can download the Kinetic Sand MSDS Sheet for your doctor or vet here.
