Tesla Coil and Lights ( Star Wars type Light Sabers )

Demo Description

Hold the metal end of the Tesla coil in one hand and a light tube in the other. The tube will light up when the Tesla coil is turned on.

Scientific Principles

  • Electrical Resonance

  • High frequency voltage can travel harmlessly and safely through the body under the right conditions.

Equipment

  • Tesla Coil

  • Light Tube

Equipment Location

  • The Tesla coil is in Kit (046) on [B-2-4].

  • A large fluorescent tube lies along the back of shelves [B-1-4] and [B-2-4].

  • Another large tube lies along the back of shelves [B-1-3] and [B-2-3].

  • Other tubes are in the extreme rear left corner of 4228 to the right of tan cabinet.







Instructions

By holding the metal end of the Tesla coil and turning it on, one may then pick up the long tube with the other hand and observe it lighting up. If students don't spontaneously start saying that they wish for “The Force” to be with you, you can make that wish for them verbally.

One may safely let a student grab the other end of the tube, or hand them a second tube which will also light up when the free ends are touched. 

Not recommended for persons with a history of  heart problems!!
