Grav® 14" Gravitron Gravity Bong
The Grav Gravitron combines the highly potent rips of a gravity bong with the cooling properties of a borosilicate glass pipe for an all-around affordable crowd pleaser that any smoker will enjoy. The 14” Grav Gravitron is the largest of Grav's namesake gravity bongs and is still as much fun to use as when it was invented back in 2004. Constructed from high grade borosilicate glass, the Gravitron is the first gravity bong you won’t need to hide away while entertaining guests. A rubber seal lines the base perimeter of the inside bottle, preventing glass on glass contact for seamless user experience. If accidents do somehow happen, all parts are affordable and easy to replace. The Gravitron even has custom parts to upgrade your new Gravity Bong with the addition of a bubbling glass downstem or a quartz dab rig nail for concentrates!
To use the Large 14” Gravitron Gravity Bong, fill the base with about 10” inches of water, or until the water level is just below the Gravitron decal. Place the bottle inside the base and pack the included 12mm bowl slide with your favorite dry herbs. Begin lighting your bowl while slowing pulling the bottle upwards at the same time. Gravity will cause the bowl to self-ignite as you continue pulling upwards and the inner bottle will fill with smoke. Finally, remove the bowl from the bottle and inhale from the mouthpiece as you push the bottle back down into the water. This movement creates a pressurized flow of smoke that results in powerful, robust hits. The Gravitron’s unique functionality is just as impressive to watch as it is to use, and you’ll understand in no time at all why this design has lasted the test of time!
