TK Plasma Ball

Incredibly cook glass sphere (5" diameter) that has glowing lightning tentacles that move with your fingers as you brush them along the glass sphere.

The plasma ball uses high-voltage alternating currents from a Tesla coil that is in its' core.  The escaping electrons cause an inert gas inside to light up!  

USB-C power port and cable included.  ALSO works with 4 AAA batteries (not included).

Sits on the tabletop or hangs on a wall.
