Glass Gravity Bong For Sale

Say goodbye to two-liter bottles and scissors. Basement-engineering meets sophistication thanks to Grav Labs. As the first fully glass gravity system, the Gravitron Gravity Bong eliminates the plastic pollutants and toxins from your smoke. 

At 9 inches tall and about 3 inches in diameter, this medium-sized piece is one of the finest gravity bongs for sale. The bottom of the GRAV decal on the outer base marks the fill line—it’s designed to hold about 4.5  inches of water. This is the second version of Grav Labs’ iconic Gravity Bong. The main differences between this piece and its predecessor are a body made of thicker glass and a 14mm male bowl held by a 19mm female joint.

To use the Gravitron Gravity Bong, begin by packing the Grav 14mm funnel bowl with dry herb. Then light it, and while doing so slowly pull the inner bottle upward. You will see the chamber fill with smoke from the bowl. Keep slowly pulling until the bottom of the glass bottle is just below the surface of the water, then take out the bowl. 

The 19mm joint can then be used as a mouthpiece. As you inhale through the mouthpiece, lower the bottle back into the chamber to push a pressurized flow of smoke up through the downstem. The inner glass will not clink or scratch against the outer glass thanks to a rubber seal lining the base of the inside bottle. 

This gravity bong is for sale now, if you’re ready to experience fast, powerful, and massive hits. It’s a fun way to smoke and provides quite the ride.
