I was flying from there to here, and while switching planes I had the pleasure to touch some kinetic sand on display at Brookstone. I have to say I was impressed. It’s just like wet sand, only it doesn’t dry, and doesn’t stick to your fingers. It’s made from 98% sand, with some proprietary coating that gives it its special properties. You can mold it, play with it, make all kinds of shapes, and start over at will. It’s just a toy (similar to the ill fated Buckyballs) that will probably lose its appeal after some time, but at $15 for a 2.2 lbs bag, it’s safely in impulse purchase territory.
