Budding designers can power up their imaginations and build coordination and creative thinking skills as they drill colorful, child-size bolts into a beautiful activity board. Just follow any of the 12 included patterns or create your own custom, glow-in-the-dark creations! With Sound Activation Mode, the lights respond to music or your voice! Just insert one of the translucent, charm-shaped bolts into the board, use the working, kid-friendly power drill to drill it in, and watch as your colorful creation glows from the inside!
