The vortex is produced when air is forced through an circular aperture, the air in the core moves with less velocity than the surrounding air that are in contact with the inner rim, this makes the air to revolve over itself creating a doughnut shaped ring. When the blast ceases the created vortex wave detach from the aperture with high velocity and could reach long distances as it moves with a minimum friction loss. If some kind of smoke, as the produced by a fog machine, is introduced inside the tube of the Vortex Generator the ring became visible producing an astounding visual effect. In many commercial devices the air blast is produced with a flexible material like plastic bag on the end of a tube that has a hole at the other extremity, but with this innovative design a solid piston compresses the air and forces it through the aperture producing a vigorous blast. The propulsive energy comes from an elastic mechanism equipped with a trigger that enable a quick release, what liberates the vortex ring with high velocity and energy.
