The honeycomb tornado perc bong from Diamond Glass is a unique and perfect mixture of disc perc. Definitely one of the best one-footers that we have, and great for a quick clean bong hit. This particular design is really great because the honeycomb perc will bubble the water up and the turbine perc will tornado it so it doesn't splash into the mouth area.
This straight tube bong is simple, durable, low maintenance, and easy to clean. Best of all, it doesn't use a downstem, so all you have to worry about is pulling just the slide to clear this tube.
