Show Me Some Science: Fog Ring Launchers
These fog ring launchers are drum-shaped with a circular hole on one end. Air is forced out through the hole and travels in a vortex, a spinning doughnut of air. It’s like a little tornado that has wrapped around in a circle. Air in a vortex travels a surprisingly long distance in a straight line. We filled our vortex canon with fog from a smoke machine, to see the vortex move!
