Have you grabbed a handful of Play-Doh recently? Stuff’s still pretty fun. But there’s that whole social stigma attached it, what with it being a “child’s toy” and all. But this new Sand by Brookstone ($25) is clearly not a toy; I mean, it even says it right there on the website, “For ages 5 and up.” Its special properties make it soft and stretchy and yet also flow-through-your-fingers-able. It sticks to itself, not you, and unlike Joan Rivers it never dries out.
