Product info
The Discovery Plasma Orb is equal parts fascinating and educating! Watch as the colorful tendrils of light jump around on their own, then follow your touch or voice, responding to physical contact, speaking, or even music! Place your fingertip on the glass surface and watch the pink and purple strands of light gather around your finger in an amazing combination of science and art! Great as a STEM display, the Discovery Plasma Orb teaches about physics and chemistry! The plasma floating around the orb is a mix of noble gasses and display the visible tendrils of light when the electrode at the center emits alternating electric currents. Placing your hand on the glass creates a discharge path with less resistance than the glass and plasma, hence why the light is drawn to your touch!
