The Gravitron is a crowd pleaser for everyone from entry-level to the aficionado. Widely known, the Gravitron is the most efficiently ruthless piece on the market.
To use the Medium Gravitron, start by filling the outer base with about 8" of water, which should hit just below the decal. Then place the bottle into the base, and load the included 12mm bowl. Place the bowl in the mouthpiece of the bottle, and as you light it slowly pull the bottle upward. The bottle will fill. When you're ready to hit it, remove the bowl and inhale through the mouthpiece of the bottle as you push it back down into the water. This will create a pressurized flow that will give you a huge hit in record time. There's a reason the world's first all-glass gravity system is still popular and iconic to this day, and that's that it does the job of delivering big, pressurized hits extremely well.
