What is a Gravity Bong?

Gravity bongs are yet another way to consume cannabis (like pipes, bongs, and vapes). Known for their extremely intense effects, gravity bongs pack a punch beyond traditional smoking methods.

Smoking out of a gravity bong creates massive plumes of smoke, which you can inhale very quickly – novice smokers beware. If you smoke something psychoactive, you’ll get high very quickly. So, ensure you’re in a safe space and ready for strong effects – have your snacks and drinks on standby!

That said, remember that the best gravity bong will not always cause a mad coughing fit. You can control the flow of smoke into your lungs, delivering massive hits without coughing your lungs out.

As the name implies, a gravity bong is a smoking device that uses gravity and water to draw smoke, and then pump it back out. Gravity bongs use gravity to pull water down through a chamber to create a vacuum that pulls air through an ignited bowl at the top. The smoke-filled air moves through the bowl and into the chamber, where it stays until the water pushes it back out again (preferably, right into your lungs). The process of forcing smoke out of the gravity bong and into your lungs is known for its strong effects.

Add clean water to the lower chamber and herbs to the stationary bowl, rotate the glass, and light it up. The smoke will fill the upper chamber as the water drains to the bottom. Rotate the piece back to its starting point and simply allow gravity to expel the thick plume.

We gave this glass gravity bong five stars because it is attractive, easy to use and maintain, and compatible with concentrates and dry herbs. Use a Studenglass gravity bong for full, flavorful, and super classy hits.

The Gleeb Glass Gravity Bong is a premium take on a classic DIY design. Whereas many DIY gravity bongs use a plastic bottle with the bottom removed.

Portability 98%

  • Portable and durable
  • No-spill design
  • Smooth, controllable smoke

Technically a “waterfall bong” and not a gravity bong, the Vortex gravity bong is a tall, sturdy piece made famous by the TV series Weeds.

Although it’s not a rotating gravity bong like the Stundenglass gravity bong, you can still drain the water from the upper chamber using a small valve to pull the smoke from a lit bowl into the chamber. Remove the bowl and take a hit through the mouthpiece comfortably, without gravity shoving the smoke down your throat.

The Vortex gravity bong comes in many colors, while its sturdy plastic makes it resistant to breakage. This piece retails at just over $100 online, making it a solid investment with a long-term payoff.

The Knockout

Durability 100%

Portability 100%

Cost 100%

  • Durable stainless steel and silicon
  • Compact and easily portable
  • Fits on any glass bottle

The Knockout is perfect for parties or those who like to drink and smoke weed simultaneously. That’s because the Knockout is a special, hand-held gravity bong that attaches to a standard glass bottle (usually a beer bottle but if you prefer Cream Soda, then have at it).

Just pop the cap of your favorite beverage, insert the Knockout and ensure a seal, pop some flower into the bowl, then flip that sucker and chug! As you drink, the smoke replaces the liquid in the bottle, which you can flip again, catch your breath, and then take your hit.

This one is a doozy, though, because you have to finish your beverage before hitting the gravity water bong, so prepare for a lot of action at once! And if you get dizzy, sit down!

Product Specifications

  • Durable stainless steel and silicon
  • Compact, an easily portable gravity bong
  • Fits on any glass bottle
  • Perfect for parties and high-energy social gatherings

What to Look for in a Gravity Bong

There are a few factors to consider to choose the best gravity bong for your needs. Primarily, you’re looking for functionality, materials, and quality of construction. Still, it’s also worth considering some things related to the buying experience, like customer service, shipping timeframes, and return policies.

Many of the best gravity bongs are made with borosilicate glass, similar to percolator bongs. This material is heat-resistant and strong, making it less likely to crack or shatter if you drop or hit it against something.

In terms of function, every gravity bong on this list will deliver the performance you need. However, if you want something more high-end, consider one of the glass gravity bongs on this list.

Every company on this list has fantastic customer service, so you can rest easy knowing that you’ll be taken care of if any problems arise with your gravity bong.

How We Select The Best of The Best

The Gleeb Gravity Bong checks all of our boxes:

  • It’s made of durable glass.
  • Its function is top-tier, delivering smooth and powerful hits every time.
  • It has hybrid functionality. So, you can use it in the traditional gravity bong manner, forcing the smoke into your lungs using water displacement, or it can be used as a “waterfall,” meaning you can take your hits using only your lung power.
  • It’s even portable, with its carrying case that doubles as a water chamber.

Considering its functionality and quality, you might expect the Gleeb Gravity Bong to be one of the most expensive on the market. However, it’s surprisingly affordable, clocking in at just $69.95 (at the time of publication – please note prices may have changed since this article was published).

How to Use a Gravity Bong

While the specific functionality of each gravity bong may vary a bit, the principle is generally the same. To use a gravity bong, you want to follow these steps:

Fill the water chamber with water. 

It should be fairly obvious where the water goes in your gravity bong. Still, for more esoterically shaped models like the Stundenglass, instructions come with your gravity bong that should explain where to add water.

Add ground flower to the bowl.

Just like any other bong, add your ground flower directly to the device’s bowl.

Light the bowl while slowly lifting the gravity bong. 

As you lift the glass bong portion out of the water chamber, you create a vacuum. The suction from the water leaving the bottle will fill the chamber with smoke. In the case of rotating gravity bongs like the Stundenglass, flip the lever on the device to create the vacuum.

Once the chamber is full of smoke, put your lips on the mouthpiece and push the device back into the water.

As the water re-enters the chamber, it will push all of the smoke out of the mouthpiece, forcing it into your lungs. This is what creates the super-strong effects that gravity bongs are known for.

You’re done!

Grab some snacks and enjoy the effects of your gravity bong.

Gravity Bong Benefits vs Regular Bongs

The main benefits of gravity bongs vs regular bongs have to do with the strength of the effects. Since gravity bongs force a whole hit’s worth of smoke into your lungs, the effects are often more pronounced. Compared with a regular bong where you can slowly take a hit at your own pace, it’s a more intense experience.

Gravity bongs also create a fun and unusual smoking experience. If you find yourself bored by the same old pipes and bongs, it’s a great way to spice up your smoking routine. They are also always a hit at parties!

Since the water is only used to create suction (and not for filtration), some users may find gravity bong hits harsher. If you want to maximize the effects of your herb while also introducing a bit of fun and novelty to your smoking experience, gravity bongs are worth a try.

How to Clean a Gravity Bong

Gravity bongs require regular cleaning and maintenance, just like any other bong. The cleaning method you should use will depend on the material your gravity bong is made with:

Glass and Borosilicate Bongs:

Start by rinsing out your bong with hot water. You can pour near-boiling water from a kettle to get it hot. Do this a few times to loosen up any residue and resin that has built up inside.

Then, add some 99% isopropyl alcohol and kosher salt. Cover the openings with your hands, and shake the bong vigorously. Since cannabis resin is alcohol-soluble, the residue inside the bong will start to dissolve into the alcohol. Salt, on the other hand, is not alcohol-soluble, so it will stay in its original form and act as an abrasive, helping to remove any stubborn stains and resin. Repeat the shaking process until the bong looks clean.

You should also disassemble the bong and soak any glass pieces (like the bowl) in alcohol for 20-30 minutes. Stir them, then make sure to rinse them out completely.

Now, rinse out the bong very thoroughly with more hot water. Make sure to rinse out any traces of alcohol remaining. Let it dry completely before using it again.

Acrylic or Plastic Gravity Bongs:

Do not use alcohol! While alcohol is the best way to clean glass and borosilicate bongs, it will degrade and damage acrylic bongs.

Cleaning acrylic bongs takes a little more elbow grease than cleaning glass ones. Simply fill the bong with hot water and dish soap, give it a good shake (while covering the openings), and use a bottle brush or pipe cleaner to scrape off any stubborn debris. You may need to do this a few times until it’s clean.

Rinse thoroughly, and let dry completely before using.

Final Thoughts: Best Gravity Bong

While it might not end up being your daily driver, a gravity bong is an essential component of any cannabis user’s arsenal. They’re fun, novel, and deliver strong effects – perfect for anyone who needs to “upgrade” beyond a regular percolator bong.

The most important things to keep in mind when buying a gravity bong are:

  • Materials and build quality. It’s worth spending a little more for a well-made gravity bong that will stand the test of time. Be wary of sub-$50 options – it’s difficult to produce a quality product at that price point. Generally speaking, glass gravity bongs are of higher quality than plastic ones.
  • Ease of use and maintenance. Once again, glass gravity bongs win out here – they’re much easier to clean.
  • Portability. If you plan to use your gravity bong on the go, something like the Gleeb kit (which comes with its carrying case) is ideal.
  • Don’t overpay. Make sure to always check AmericanMarijuana for coupons and deals to get the best price possible.

Once you’ve chosen a gravity bong, sit back, relax, and enjoy some seriously potent tokes. If you crave even stronger effects, then we suggest looking into dabbing concentrates.
