An air vortex cannon is a toy that releases doughnut-shaped air vortices — similar to smoke rings but larger, stronger and invisible. The vortices can ruffle hair, disturb papers or blow out candles after travelling several metres. An air vortex cannon can be made easily at home, [1] [2] from just a cardboard box. [3]

An air blaster or air cannon is a de-clogging device with two main components: a pressure vessel (storing air pressure) and a triggering mechanism (high speed release of compressed air). They are permanently installed on silos , bins and hoppers for powdery materials, and are used to prevent caking and to allow maximum storage capacity.
