EUC! Fun retro light for your dance party, DJ booth, bar, mad scientist lab, hipster office cubicle or anywhere you’d put a lava lamp. Turn it on and the lamp produces what resembles lightning or electrical current in 4 different colors. Reacts to touch, also has a sound sensitive mode, or just sit back and watch it perform. Light field is approx. 6” circle. Operates on batteries or included AC plug. Makes a great gift for your favorite groovy human!
