Want to make sand castles on your desk at work? Winter snow got you down? Bored with shaping putty? Then check out this cool new Smart Mass Kinetic Sand. This magic sand acts just like wet sand from the beach when it is molded and shaped, but acts like flowing dry sand when allowed to break apart and collapse. Unlike wet beach sand, this kind can be used indoors without any mess (it only sticks to itself), never dries out, and is residue and stain free. It's made from 98% pure sand, is 100% safe and non-toxic, and is wheat, gluten, and casein free.
