A touch of joy! A touch of science! A touch of fun! The Mini Plasma Ball is great as a gift, desk toy or just to have around!

Light responds to your touch! Simply place your hand on its smooth glass surface and watch as the plasma beams get thicker. The unchained lightning is drawn to your touch. Let people see electricity follow your skin because it can’t help but be attracted through this ball. It gathers harmlessly about your palm and fingers, creating beautiful swirling formations that follow your every move.

One of the cool plasma ball lamp tricks you can do is place a Neon lightbulb next to it and watch it light up. It's not magic, it's science! The electromagnetic field that forms close to the glass surface of the plasma ball is exciting the Neon gas which then emits light.
