Tesla coils are wonderful physics toy that put on an electric show. They may sound scary but many smaller models are safely touchable. This tiny Bluetooth tesla coil is one of the smallest ones we have seen. It has a transparent cover, so you can see the electronics inside. It also has knobs to adjust frequency and arc size.
In regular mode, you can simply interact with this tesla coil using gas tubes and other fun accessories. In the music mode, you are going to need to play Square Wave music through your smartphone. You can always put a glass on top of the discharge needle to turn this into a plasma lamp.
