The Gravitron has remained the most ruthless, yet efficient, smoking device on the market for a reason. The Gravitron is the first affordable glass gravity bong ever made and a true crowd pleaser for everyone from entry-level smoker to aficionado toker. A rubber seal lines the base perimeter of the inside bottle, preventing glass on glass contact for a seamless user experience. If accidents do 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! The Grav 11” Gravitron, or Medium Gravitron, is the smaller edition of Grav’s flagship product, and still as much fun to use & hard-hitting as it was way back in 2004 when it was invented.
The Medium 11” Gravitron is super easy to use. Start by filling the outer base with about 8” inches of water, which should hit just below the decal. Then place the glass bottle into the base, and load the included 12mm bowl with your dry herbs. Place the bowl in the mouthpiece of the bottle, and light your herbs while slowly 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. When you're ready, 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 of smoke and offer huge hits in record time. Get yourself a gravity bong you’ll be proud to keep on display with the Grav 11” Gravitron!

After my tolerance kept getting higher I wanted a one hit and done piece but my friends and I like to smoke it till we drop. The bowl can be packed for a very large rip that will send you to another planet :)
This is a great piece that I do not regret purchasing. Hits smoothly while still producing a large cloud of smoke at the same time.
Outstanding purchasing experience with CaliConnected. I received my Gravitron in 2 days! Love it.
Great! Gravitron Bong brings you into space!
Let me start by saying I love this piece, it’s exactly what I was looking for when I was tired of homemade pieces honestly. I ordered one just for the **** of it, and it got here, to me, in less than a week! Not to mention, they only made me pay like 15 bucks down, and I have 3 more 15 dollar payments to make every two weeks! How great is that?? (Shoutout To SEZZLE For financing) Great, strong, and DISCREET shipping, it made it to me in one piece. I would recommend any smokers I know to try this and I intend on buying more from Caliconnected. My only “complaint” is that I WISH that I got some stickers from Gravitron! So I could decorate my other stuff with them! Please send STICKERS!! Thanks CaliConnected PS - I JUST FOUND A SNEAKY THAT CALICONNECTED SENT INSIDE THE PACKING PEANUTS IN THE BOX AND A COOL MAGNET! Thanks again CaliConnected!
Thanks for the great review! We must have ran out of Gravitron stickers when your order was sent out, but if you leave a note on your next order and we have them available again we'll be sure to include some!
