This medium Gravitron from GRAV is 28cm tall and was designed by Dave Daily. The outer base has a diameter of almost 9cm is designed to hold 25.5cm of water.
As you pull the inner bottle slowly upwards, hold a flame to the fully packed bowl, filling the bottle chamber with thick white smoke. Remove the bowl and place your lips on the stem of the bottle. Lower the bottle and slowly inhale as the chamber of smoke is forced into your lungs.
The Gravitron is GRAVs namesake piece and the first all-glass gravity bong.
GRAV is based in Austin Texas. It made a name for itself producing high-quality hand made glass bongs and pipes for affordable prices.
Their concept is to purely concentrate on producing the most scientific glass pipes and bongs on the market.
They do this by collaborating with some of the most well-respected glass artists in the world to create unique designs that you cannot find anywhere else.
