Remarkably, Kinetic Sand moves by itself as you work with it. It continually rearranges itself. Squeeze it, shape it, build something small. Build something big. Visibly it quick-melts, and the movement is fascinating! Kinetic Sand is 98% pure sand and 2% of non-toxic polymer. It moves like dense fluid without making a mess. It sticks to itself, so cleanup is a breeze. Kinetic Sand soothes and engages both kids and adults, in schools, at work, in therapy sessions, and at home. Not all things are permanent, except maybe fascination with Kinetic Sand.
