Capacitor Discharge Vortex Cannon

Vortex cannons are a device that fires doughnut-shaped air vortices. The vortices are able travelling several metres and can be visualised using smoke. Vortex cannons have been around for a long time from large weather cannons to everyday science toy.

The aim of this project is to build portable rapid fire electric vortex cannon using a large woffer speaker and high voltage capacitor discharge circuit.
