The Acrylic Large Double Bubble Bong is a wickedly clever smoking device, featuring two separate chambers with a large bubble at the base of each. One chamber sits atop the other, and they are joined only by two brightly coloured tubes, which lead from the lower bubble into the upper bubble. The double chamber effect helps give the bong a much cooler and smoother smoke, as the inhaled smoke has further distance to travel from the bowl to the lungs.

Both parts are well supported, with the lower bubble chamber having a rounded and removable base and the upper bubble slotting neatly into the top of the lower shaft.

It might be just a little bit crazy looking, but it's a hell of a lot of fun and the double-chamber effect really does provide a fantastic smoke.
