A touch of joy! A touch of science! A touch of fun! The Mini Plasma Ball is great as a gift, desk toy or just to have around! Light responds to touch and the music in a room! Simply place your hand on its smooth glass surface and watch as the plasma beams get thicker. The unchained lightning is drawn to your touch. Let people see electricity follow your skin because it can’t help but be attracted through this ball. It gathers harmlessly about your palm and fingers, creating beautiful swirling formations that follow your every move. It even reacts to music, your voice and other sounds! Just tune it to respond to sound and it actually reacts to music with rhythmical flashes of lightning. You can even talk to it and see the patterns of your voice reflected in its striking pulsations.
