Okay kiddo, do you know what a tesla coil is? It's a special toy that makes lightning bolts! It uses something called electricity to make really cool sparks!
Now, imagine if we added singing to that. That's what a singing tesla coil is! It's a special type of tesla coil that makes different sounds and pitches, kind of like music!
But how does it work? Well, the tesla coil uses special technology to make electricity go back and forth really quickly, and this causes the lightning bolts to form. The singing tesla coil adds some extra technology to make the electricity go back and forth even faster, which makes different pitches and sounds.
And the best part? You can even use a keyboard to play music through the singing tesla coil! It's like playing a really cool piano that also makes lightning bolts! How awesome is that?!
