A little bit of science, a little bit of art, and a whole lot of cool! This Plasma Ball is simply the ultimate interactive light show. Blending specially formulated inert gases, it creates a dramatic display of light inside a glass sphere! Fascinating to watch, this light is even more fun to play with! Just place your fingers on the glass surface and watch as colored bolts of glowing light follow your every move. Also includes a built in music sensor that will respond and move in queue with the beat of a song for a light show that never stops! AC powered adapter included.
