Product Description


Place this spinner on top of your tesla coil and watch the sparks shoot out of the tips of the spinner as it begins to turn. Will work on core & coil, solid state, and vacuum tesla coils alike. Best-suited for use on our BTC30 and BTC40-series tesla coils, but may also work on smaller and larger coils to varying effect. Since the electrons are mutually repelled from each other, this forces them to travel down the arms and be emitted at the pointed ends, causing this rotor to spin at increasing speeds, emanating sparks as it goes.

A fun accessory for your BTC30 and BTC40-series tesla coil!

    Assembly was pretty straightforward. It did shock me and I have a new respect for high voltage. The amazing thing was at night I saw the purple light eminating from the edge of the spinner I had attached.
