Gravity bongs are one of those things that sound intimidating until you actually use one. Basically, you are using water and air pressure to create one of the most efficient cannabis smoking devices out there, letting physics do most of the work until the very end. 😏 This guide breaks down how a gravity bong works, what each part does and how to use one in a way that feels approachable. Scroll down, get familiar with the mechanics, and see why the NWTN Home Deco Gravity Bong, available at Pure Blossom dispensary in NJ, has earned a permanent spot in our rotation.

What is a Gravity Bong
A gravity bong is a water-assisted device that uses displacement to fill a chamber with smoke. Gravity bongs have been around for decades, but modern designs like the NWTN Home Deco Gravity Bong bring consistency, control, durability (and beauty, if we do say so ourselves) to a method that was once strictly duct tape and cut-off two-liter Mountain Dews. As water moves out of the way, smoke naturally fills the empty space left behind. When the water moves back in, it gently pushes that smoke out in one smooth release.
Because the chamber can hold a larger volume of smoke (and because it’s being forced by the laws of physics directly into your lungs), gravity bongs often feel stronger than standard bongs. You’re inhaling a more concentrated amount at once, and the process tends to be faster due to gravity and water pressure doing most of the work. That said, the experience is very adjustable depending on how you use it.
The Parts
Most gravity bongs share the same basic structure, even if the design or material varies. With the NWTN HOME Deco Gravity Bong, everything below is included.
- The shell – The bottom vessel that holds the water.
- The core – The chamber sits inside the base. It rises and lowers during use. As it lifts, smoke fills the space inside and becomes a temporary holding area for the smoke.
- The gasket – A Deco Gravity Bong comes with a silicone gasket to prevent clinking and/or breakage.
- The slide/bowl – The bowl sits on the top of the chamber. This is where ground flower is packed and combustion happens.

How the Deco Gravity Bong Hits
- Fill the base about three-quarters of the way with water. Pro tip for smoother hits: use fresh, cold water.
- Lightly pack the bowl with ground flower and set aside.
- Insert the chamber into the base and stack the packed bowl on top.
- Once you are ready, light the bowl and slowly lift up the chamber. As the chamber rises, water drains and chamber should fill with smoke.
- Continue lifting until the chamber is filled with smoke and there is still a small amount of water sealing the bottom. At this point, it’s ready.
- If the chamber is lifted completely out of the water, the seal breaks and the smoke will dissipate.
- Stop lighting and carefully remove the bowl.
- Place your mouth over the opening and gently push the chamber back down to release the smoke at your own pace.
Tips for First-Timers
Your first time will likely involve some aggressive coughing and a newfound respect for atmospheric pressure, but that’s all part of the experience. Remember, you’re in control of the pace!
Start small and see how your body responds. You don’t need to inhale everything in one go.- It’s normal if it takes a few tries to get comfortable with the lift-and-lower motion.
- Adjusting the water level can change the intensity. Less water often leads to a lighter hit, while more water can increase pressure.
- Focus on steady breathing rather than force.
Keeping it Clean
Dirty bongs can ruin your sesh and waste good flower. Residue builds up fast, making hits harsher and muting flavor. Stay ahead with a quick rinse after your sesh and save yourself a much bigger cleanup later.
How to clean:
- Disassemble the bong and rinse each piece with warm water to loosen residue.
- Add isopropyl alcohol and coarse salt to the chamber, bowl, and any areas with buildup, then gently swirl or scrub.
- Rinse thoroughly with warm water until clean.
- Allow all pieces to air dry completely before putting everything back together.
Prevention tip:
- If you want to stay ahead of buildup, try Piece Water Solution, an all-natural bong water alternative that helps prevent resin from sticking in the first place. It’s slightly thicker than water, which helps filter smoke and cleanup is easy. When you’re done, a warm water rinse is usually all it takes. No harsh chemicals required.
