Happy Uncommon Instruments Awareness Day! So, to raise awareness for the unusual jammin' tools . . . here are some of the weirder ones we could find on the Internets.
This one's my favorite. These are two gigantic solid state musical Tesla Coils. A Tesla Coil is a special type of transformer invented by Nikola Tesla that is able to generating extremely large voltages using a phenomenon known as electrical resonance. Each coil in this video is capable of generating a 13 foot spark.
