Product Information

Graphically demonstrate the formation of visible vortex smoke rings with this teacher-designed “air blaster”.

Show how the formation of the ring is dependent on the shape of the opening using the included capplugs (you choose and cut the shapes), as well as the effects of other variables.

Generate smaller rings and examine the tiny concentric circles and parallel lines of particles that form them. Make comparisons between rings formed in air and those formed in water. You can even blow out a candle at 10 meters.

Developed by Bruce Yeany. Includes instructions.
