This is the original LAVA brand lamp which has been designed in the LAVA World's trademark shape for over 40 years! But why limit this classic to just melting wax? Now this lava lamp sends bolts of lightening through a violet/blue mist & if you touch the sides, the bolts of electricity are attracted to your fingers. Just like plasma balls, this is completely harmless. The lamp can be run normally, or with a sound activated feature. In the mid-sixties, LAVA invited a generation to turn on (their Lava brand lamps), tune in, & drop out. The introduction of the Century LAVAbrand motion lamp started it all. Originally sold as the Astro Lamp, with its large gold base & tiny holes, it produced a simulated starlight that was definitely far out man! Still the original Lava Lamp shape but with electricity bolts rather than melting wax, & all held in place on a stunning black stand!
