Thames & Kosmos Plasma Ball 678001

Learn about electricity, matter and energy and marvel at the wonders of the universe with this mesmerising electric light show. The plasma ball creates a fascinating display of glowing electric tentacles, like lightning flowing from your fingertips. Display it on a table, desk or hang it on a wall like a sconce. 

Plasma is the fourth state of matter. Neither solid, liquid, or gas, it is a super-charged ionised gas found in every star. The plasma ball works by sending a high-voltage, alternating current from a Tesla coil at its core, through a noble gas, to the inner surface of the glass sphere. Escaping electrons cause the inert gas inside the sphere to light up, creating the amazing effects. You can actually see electricity in the palm of your hand with this incredible device. Turn on the sound-activated mode and watch the plasma arcs dance to the beat of your favourite song.
