7-Inch Interactive Plasma Globe

The PlayBees plasma ball is a 7-inch glass sphere that produces coloured electrical filaments using a built-in Tesla coil. It is designed for children and adults who want a visual demonstration of static electricity and noble-gas excitation in a decorative format.

Touch and Sound Reactive Modes

The unit offers two interactive modes: a touch-sensitive display where filaments follow fingertip contact, and a sound-reactive mode that synchronises the light patterns to nearby audio. A 6-foot mains cord supplies continuous power without the need for batteries.

Suits STEM Curiosity and Party Decor

Buyers seeking a hands-on science prop or ambient lighting for gatherings will find it useful. Those who need a battery-operated or portable device, or who require a larger globe for classroom visibility, should consider other options.

Questions about this item

Does the glass globe ever need to be replaced or refilled with gas?

The globe is a sealed vacuum-pressurised unit with no user-serviceable parts; it is designed to run indefinitely on mains power without refills or globe changes.

What stops the unit from running continuously at a party or in a display cabinet?

The 6-foot mains cord supplies constant power, so the only practical limit is the availability of a wall socket; there is no internal battery or thermal cut-out mentioned.
