This little gadget fills your room with tons of swirling rainbows---all through the power of the sun! Find a sunny window and affix the suction cup on the back of the rainbow maker to the window. The sunlight pours in, enters the little solar panel on the top and powers the gears in the center that spin the crystal. The sunlight also hits the crystal at the bottom and shoots rainbows all over your room--creating a solar-powered disco. This is a great eco-friendly baby gift, too (get 'em started early on renewable energy)--perfect for nurseries. At under twenty bucks, it's priced to move. Get it here.

Some suggested jams for your solar-powered dance party:
