A gravity bong uses water pressure rather than lung power to move smoke through a chamber. As water falls or is displaced, it pulls smoke along with it, so the draw is generated by the device instead of by you inhaling hard.

Two connected glass globes sit in a frame that rotates a full 360 degrees. You load the bowl and turn the frame over. Water moves from the upper globe to the lower one and pushes smoke through the liner toward the mouthpiece as it goes.

A standard water pipe still needs you to pull the smoke through. Here the falling water does that. You are not creating suction, you are receiving what the rotation has already pushed out, which is why the draw stays even the whole way.

The Modul is a battery vaporizer for dry material. It runs on its own as a portable device, or it docks onto the gravity frame so the rotation pulls vapor instead of smoke. It costs three hundred forty nine ninety five on its own.

No. Grateful Dead, Tyson 2.0, Wiz Khalifa and Cookies editions use the same patented rotating mechanism as the standard piece. What changes is the finish, the packaging and what is included, not how it performs.

The standard Gravity Infuser ships with a three foot silicone hose, a 14mm male adapter, a cleaning kit and a reusable craft box. The Dok travel sets add the dock and a fitted case built for carrying rather than sitting on a shelf.

Yes, through the Modul with the quartz concentrate tank fitted. The tanks swap, so a single Modul handles dry material or concentrate depending on which one is installed. Each tank is seventy four ninety five.

Empty the water after each session, then run isopropyl alcohol and warm water through the globes and the hose. The cleaning kit in the box covers the frame. Do not soak the aluminum frame itself, and let the glass dry fully before reassembling.

Swap tanks start at seventy four ninety five. The Modul is three hundred forty nine ninety five. The standard Gravity Infuser is four hundred forty nine dollars, and the deluxe travel sets and artist editions run four hundred ninety nine and up.

It depends what you want from it. Nothing else delivers a rotation driven draw, and the build is aircraft grade aluminum and borosilicate rather than cheap glass. If you mainly want filtration and not the mechanism, a standard water pipe costs far less.
