Want to build sand castles but don’t want to go outside in the hot, hot sun? Too bad! Just kidding, that’s totally possible thanks to Sand by Brookstone. It looks and feels like sand, but functions a bit like silly putty, letting you shape it into anything you can imagine. Surely this stuff is made of magic right? Nope, it’s actually 98% sand and 2% polymer. And unlike regular sand (which is actually 98% sand and 2% broken glass, trash, and stuff that makes you say, “Ew what is that?”) it won’t stick to you, dry out, or make a mess.
