Thames & Kosmos Plasma Ball - Touch Sensitive Lightning Globe for Science Experiments & Home Decor | Perfect for STEM Learning, Gifts & Party Decorations

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.
