New and super cool: solar-powered Emoticons! (Parents: Emoticons are what your kids put in emails and texts to show their mood, in case you're not up to speed.) Like :) and :(- got it. And SOLAR POWERED. Yes, solar powered. These bands are translucent white when indoors, but when you wear 'em in the sun, the colours change to red, purple, or blue before your eyes. Back indoors, they change back to white again and again. How cool is that. Like emoticon magic, we tell ya!
