Tesla Tornado Christmas Tree

Step 8 Fun Things To Try

 I used red and silver sparkles to add some zest. Too many sparkles of large size will clog the discs temporarily. If that happens, turn off the vortex and wait a few seconds, then turn it on again...that will tend to purge the clog. In retrospect, the disc spacing could be wider to accommodate this. 1/16 to 1/8 inch disc spacing would likely work better with the sparkles.

Add coloured lights behind the poly tube for cool effects. A flashlight or laser shining into the vortex from the top works good too.

I added a ping-pong ball and got interesting effects. The ball can be held completely submerged in the vortex, and its height can be controlled easily with the speed of the Tesla disc pump.
