Grav Labs Gravitron

The GRAV® Medium Gravitron is the smaller edition of gravity bong and it's still as much fun and as hard-hitting as it was back in 2004 when it was invented!

This is one of Grav Lab’s signature creations. One of the first things they came out with is the Gravitron, now available in two sizes.

  1. To use the Medium Gravitron, start by filling the outer base with about 8" of water, which should hit just below the decal.
  2. Then place the bottle into the base, and load the included 12mm bowl.
  3. Place the bowl in the mouthpiece of the bottle, and as you light it slowly pull the bottle upward.
  4. The bottle will fill with smoke.
  5. 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.
  6. This will create a pressurized flow of smoke that will give you a huge hit in record time.

There's a reason the world's first all-glass gravity smoking system is still popular and iconic to this day, and that's that it does the job of delivering big, pressurized hits extremely well.

No smoke is lost because of the design of the inner chamber, so smoke can be inhaled without leaking. This piece is made from extra heavy glass, making it nice and durable. Add the Gravitron to your collection today, it won't disappoint.
