7B35.76 - Plasma Tube
Demonstrate high temperature plasma and radiation transmission in a quick safe manner
Plug the tube into the high frequency, high voltage power supply. Choose a frequency setting (toggle switch), then vary the amplitude to change the point where the plasma will reach inside the tube.
Turn on the power supply. Choose a frequency setting (toggle switch) and adjust the amplitude to change the pattern produced and height it reaches within the tube. By touching the surface of the tube with your hand, you cause the plasma to spark directly to the glass where your hand is located.
