Kinetic Sand - 11 lb ($42.95) 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! It looks like real sand, because it is 98% pure sand. It moves like dense fluid without making a mess. That's the 2% of non-toxic polymer. It sticks to itself, so cleanup is a breeze.
