Tornado Cyclone bongs are bongs with a cyclone perc, which is a flat disc extended over the entirety of the tube, with small angular slits. Cyclone Bongs will then spin the water at an angle when water is pulled through, giving the piece a very unique tornado effect in the water, thus they are often referred to as tornado bongs or tornado cyclone bongs.
