You kind of have to watch this video. It’s a short clip with Jem Stansfield from the UK show Bang Goes The Theory where he demonstrates a vortex cannon. This device will shoot out air at 200mph, in what looks like a smoke ring but is in fact moisture from the air condensed into visibility by the pressure differential within the vortex.
Who cares? Well just watch the video and see what a friggin’ little cloud can do.
