Grav Labs XL Gravitron Glass Gravity Bong

Grav Labs brought sophistication to the basement-made gravity bong. Gone are the days of scissors and 2-liter bottles of Mountain Dew. The Gravitron bong is the first all-glass gravity system, so plastic pollutants can no longer infiltrate your smoke. 

The extra large Gravitron bong is 14 inches tall and 3.5 inches in diameter. The outer base is designed to hold 10 inches of water—the fill line sits right below the bottom of the GRAV decal. The 12-millimeter bowl is first packed with dry herb and then lit. As the inner bottle is pulled slowly upward, smoke from the bowl fills the chamber. Once the bowl is removed, the 16-millimeter downstem doubles as a mouthpiece. Lowering the bottle back into the chamber forces smoke up through the downstem in a pressurized flow as the user inhales from the mouthpiece. A rubber seal lines the base of the inside bottle, so the inner glass will not clink or scratch against the outer glass. This powerful gravity bong results in fast and massive hits. 

But don't be afraid to take a spin on the Gravitron. It's a fun ride.

 

More about the Gravitron Bong

The Gravitron bong was designed by Grav Labs CEO, Dave Daily, in 2004 as originally the only product the company sold. The Austin-based brand remains a respected name in the scientific glass game. They design, manufacture, and distribute some of the most recognizable pieces on head shop shelves, most notably the Gravitron. The well-known design marks an important place in toker history, and the glass gravity bong is just as beloved today as it was then.
