STEM Plasma Ball Kit - A mesmerizing light show. The plasma ball creates an exhilarating display of electric tendrils, like lightning flowing from the tips of your fingers. Plasma is the fourth state of matter. It is neither solid, nor liquid, nor gas, but an ionized gas found in every star.

It works by sending a high-voltage alternating current from the Tesla coil at the center, through a gas, to the inner surface of the glass sphere. The escaping electrons ignite the inert gas inside the sphere, creating the stunning effects. With this amazing device, you can truly see electrical energy in the palm of your hand.

The design of the sphere allows you to display it on a table or hang it on the wall, like a piece of art. It can be powered via a USB-C cable or with batteries. Activate the sound mode and watch the electric arcs dance to your favorite beats.
