Plasma Ball / Tesla
Light object with interactive display
Nikola Tesla 1894 / Modern version: Bill Parker at MIT 1971, James Falk for Groundstar 1980
Glass, neon gas, xenon gas, electronic circuits, ABS, cord
A small Tesla coil generates a large electrical potential difference, which tries to even itself out by discharging—in the same way that a cloud discharges lightning. Watch the plasma streams move toward your uncharged finger as you touch the ball, or make them respond to sound and music.
NB: Features a sound sensor mode: reacts to music when close to a speaker. For ages 8+
