Welcome to the ultimate collection of bongs with one of the most unique percs available - the turbine perc. Turbine Percs consist of a solid disc, that almost seems to block your tube, but actually have several slanted slits on the sides that allow water to be propelled upwards at an angle, creating a rather interesting tornado effect. Better than just providing users with a cool effect though, this tornado vortex of water cools smoke at rapid speeds, while simultaneously preventing any water from splashing straight up during use!
