GRAV Large Gravitron Gravity Bong 29cm

Prepare for takeoff with the all new and improved GRAV Large Gravitron Gravity Bong 29cm. If you're looking for a seriously good time with your mates, you can't go pass the world's first all-glass gravity bong. The fresh facelift boasts a fivefold increse in glass thickness for ultimate durability and stability as well as an upgraded platinum cured silicone grommet for a tighter seal.

The added customisability of the 18mm female ground joint now allows you to use any 18mm male cone piece giving you full control of the look of the bowl as well as quick replacement if an unfortunate breakage occurs. Plus, the added flange at the top of the neck gives you a better grip making lifting the bottle an absolute breeze. Standing at 29cm, it's the biggest version of the Gravitron available and even has a rubber seal at the base of the inside bottle so there's no glass-on-glass contact. 

Through the magic of gravity and pressure, the Gravitron creates huge, smooth and efficient hits every single time. Simply fill the base halfway with water, pack your bowl and insert it in the joint at the neck. Light it up and slowly lift the bowl simultaneously. Once the bottle is filled with smoke, remove your bowl, place your mouth over the neck and launch yourself into the stratosphere. The scientific and functional design creates a dense and pressurised hit without losing any smoke in the process. Sure, it's great for parties with your mates, but because it's one of the most efficient smoking devices on the market, it's the perfect affordable all-round bong for your personal collection.
