These videos will help show the lighter side of physics with amazing experiments, funny raps and explanations of concepts in terms students can understand.
Check out this video to hear the amazing noises the high-voltage sparks emitted by this Tesla coil produce.
This is a solid-state Tesla coil. The primary runs at its resonant frequency in the 41 KHz range, and is modulated from the control unit in order to generate the tones you hear.
