What is a Gravity Bong?

Gravity bongs are another way to consume cannabis, similar to pipes, bongs, and vapes. They are known for delivering very intense effects that go beyond traditional smoking methods.

Using a gravity bong creates large clouds of smoke that you inhale quickly. So, beginners should be cautious. If you’re smoking something psychoactive, expect to feel the effects fast. Make sure you’re in a safe place and have snacks and drinks nearby.

That said, a good gravity bong won’t always cause coughing fits. You can control the smoke flow to take big hits without overwhelming your lungs.

As the name suggests, a gravity bong uses gravity and water to draw smoke and then push it back out. When you light the bowl at the top, gravity pulls water down through the chamber, creating a vacuum.

This vacuum pulls smoke through the bowl into the chamber. The smoke stays in the chamber until the water pushes it out, usually right into your lungs. This process is what gives gravity bongs their strong effects.

We had the chance to try the Studenglass gravity bong, and we were seriously impressed. This thing looks amazing on a table; sleek, modern, and built with quality materials. The rotating glass chamber and the soft, three-foot silicone hookah hose make it easy and comfortable to use.

To get started, we filled the bottom chamber with clean water, packed the bowl with herbs, and rotated the glass. Once lit, the smoke moved smoothly into the top chamber while the water drained below. We turned it back around and let gravity do the rest. The smoke came out thick, smooth, and flavorful; no effort needed.

What stood out most was how easy it is to use and clean. Plus, it works with both flower and concentrates, which gives us a lot of flexibility. We gave the Studenglass a full five stars for its clean look, strong performance, and overall experience. It’s the kind of piece that feels just as good to use as it does to show off.

Product Highlights:

  • Eye-catching glass design
  • Smooth 360-degree rotation
  • Easy to take apart and clean
  • Works with both flower and concentrates
  • Backed by a 1-year limited warranty

We tried the Gleeb Glass Gravity Bong and loved how it brings a smart upgrade to the old-school DIY method. Instead of cutting up a plastic bottle, Gleeb gives you a solid glass piece that feels much safer and cleaner to use.

What we liked most is that it removes the risk of inhaling chemicals like BPA, which is often found in heated plastic. With the Gleeb, we didn’t have to think twice about what we were breathing in. Just good, clean hits.

It’s also super portable. The glass bong comes packed inside a smell-proof case that doubles as the bucket. That made the setup fast and easy, whether we were at home or on the move. The whole thing gave us a wave of nostalgia, but with better materials and smarter design. We gave it five stars for being sturdy, simple, and surprisingly affordable.

Product Highlights:

  • Durable glass gravity bong
  • Great for travel
  • Smell-proof case doubles as a water container
  • Budget-friendly price

  • Attractive, hourglass-shaped glass gravity bong
  • Multi-use functionality
  • Universal 14mm Joints

We tested the Infinity Waterfall and were immediately drawn to its eye-catching hourglass shape. It’s a beautiful piece of glass that stands out on any shelf, but it’s more than just looks. This bong offers a flexible setup that let us switch between gravity and traditional water bong functions with just a quick bowl change.

The universal 14mm joints were a big plus. We connected different accessories like mouthpieces, bangers, and down stems without any hassle. It gave us the freedom to change up our sessions based on what we were in the mood for. Whether we wanted a smooth gravity pull or a classic water bong hit, the Infinity handled it all.

We gave it 4.5 out of 5 stars for its stylish build, versatility, and ease of use. It’s a strong choice if you like to mix things up and want a piece that’s both fun and functional.

Product Highlights:

  • Switches between water and gravity bong

Vortex

Vortex

Durability 100%

Portability 98%

Cost 97%

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

We tried out the Vortex and immediately saw why it has such a loyal following; it’s simple, effective, and delivers smooth hits without the harsh push some gravity bongs are known for.

Technically, the Vortex is a waterfall bong, not a gravity bong in the traditional sense. It doesn’t rotate like the Studenglass, but it still fills the chamber using water pressure and a small valve. Once the bowl is lit, smoke pulls into the upper chamber with control. After that, all we had to do was remove the bowl and inhale. The result? A steady, easy draw without any sudden rush.

We also liked how tough the thing is. It’s made of solid plastic, and the no-spill design gave us confidence while using it indoors and outside. With several color options and a price point just over $100, the Vortex felt like a smart buy.

Product Highlights:

  • Strong, travel-ready design
  • Controlled smoke draw, no harsh hits
  • No-spill valve system
  • Ships fast with priority delivery

The Knockout

Durability 100%

Portability 100%

Cost 100%

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

We brought the Knockout to a party and it was an instant hit. This thing combines two favorites — smoking and drinking — into one wild experience. It’s a compact gravity bong that fits right onto any standard glass bottle. Beer, soda, whatever’s in your fridge!

Using it was simple. We cracked open a drink, slid the Knockout into the bottle, and packed the bowl. Once sealed, we flipped the bottle and started drinking. As we chugged, smoke filled the bottle. When we finished, we flipped it back, caught our breath, and took a strong, flavorful hit. It was fast, intense, and way more fun than expected.

It’s definitely one of the more active setups we’ve tried. You have to finish your drink before hitting the bong, so it’s a lot at once. If you’re new to this, sit down first (you’ll thank us later).

We loved it for parties and social settings. It’s small, durable, and easy to take anywhere. Big laughs. Big hits.

Product Highlights:

  • Strong stainless steel and silicone build
  • Fits most glass bottles
  • Easy to carry and use anywhere
  • Great for parties and group sessions
The Bukket

  • Portable
  • Compact
  • Dishwasher safe

We got our hands on the Bukket and quickly saw why it’s a fan favorite. Made by Everyone Does It in the UK, this award-winning gravity bong (yep, High Times Cup winner back in 2001) packs a serious punch without needing a drop of water.

This accordion-style bong surprised us with how much smoke it can produce in just a few seconds. We pulled massive, dense hits almost instantly. It’s super lightweight, easy to stash in a bag, and best of all, it’s dishwasher safe. Clean-up was a breeze.

We will say this one isn’t beginner-friendly. It took a little practice to get the inhale just right without overdoing it. But once we got the hang of it, the Bukket became one of our favorite go-to travel pieces. At under $30, it’s hard to beat.

Product Highlights:

  • Compact and great for travel
  • No water required
  • Easy to clean (dishwasher safe)
  • Delivers fast, powerful hits

Find Your Perfect Match: Gravity Bong Buyer's Guide

What to Look for in a Gravity Bong

Choosing the right gravity bong comes down to three things: function, material, and build quality. It also helps to look at customer service, shipping speed, and return options before you buy.

Most top-rated gravity bongs are made from borosilicate glass (similar to percolator bongs). This heat-resistant glass is strong and less likely to crack or break. If you’re aiming for long-term durability, this is the material to go for.

All of the gravity bongs featured in this guide offer strong performance. If you’re looking for a high-end option, the glass models on this list are your best bet.

Custom service also matters. Every brand mentioned here has responsive support, giving you peace of mind in case any issues come up.

How to Use a Gravity Bong

While each model is a little different, gravity bongs all follow a similar process:

1. Fill the chamber with water.

Most designs make it clear where the water goes. For more complex setups like the Studenglass, follow the included instructions.

2. Add ground flower to the bowl.

Just like with any bong, pack your herbs into the bowl.

3. Light the bowl while lifting the bong.

As the bong rises, it creates suction that pulls smoke into the chamber. On rotating models like the Studenglass, flip the lever to start this process.

4. Inhale the smoke.

Once the chamber fills with smoke, place your mouth on the mouthpiece. Push the bong back down or rotate it. This pushes smoke out of the chamber and into your lungs.

5. You’re done!

Grab a snack, sit back, and enjoy the effects.

Gravity Bong vs. Regular Bongs: What's the Difference?

Gravity bongs create stronger effects because they push a full chamber of smoke directly into your lungs. Regular bongs let you control the speed of each hit. With gravity bongs, the hit is immediate and intense.

They also offer a more exciting experience. If you’re tired of the same routine, gravity bongs add novelty and make a great party piece.

Keep in mind that gravity bongs use water for suction, not filtration. This can result in a harsher hit, especially for those with lower tolerance. Still, they’re a great option for users who want more impact from each session.

How to Clean a Gravity Bong

Regular cleanings keep your gravity bong working well. Use the right cleaning method based on the material:

Glass and Borosilicate Models

  1. Rinse with hot water to help loosen resin and other residue.
  2. Add 99% isopropyl alcohol and kosher salt. Cover openings and shake. The alcohol breaks down the resin while the salt scrubs the interior.
  3. Soak glass pieces separately. Soak bowls and small parts in alcohol for 20-30 minutes. Stir occasionally.
  4. Rinse thoroughly. Use more hot water to remove all traces of alcohol. Let dry fully before reuse.

Arcylic or Plastic Models

  1. Avoid alcohol as this damages plastic and causes long-term wear.
  2. Use hot water and dish soap. Shake the bong with soapy water. Use a pipe cleaner or bottle brush for tough spots.
  3. Rinse and dry. Make sure all soap is gone before using it again.

Why We Recommend the Gleeb Gravity Bong

The Gleeb Gravity Bong hits all the right notes:

  • Built with sturdy glass
  • Delivers smooth, powerful hits
  • Works as both a traditional gravity bong and a waterfall bong
  • Comes in a smell-proof case that doubles as the water chamber
  • Costs only $59.95 (at time of writing), with an extra 5% off using coupon code AMMA

The Gleeb is one of the most affordable and versatile options on the market.

Final Thoughts: Choosing the Best Gravity Bong

A gravity bong may not become your everyday piece, but it’s a must-have for any cannabis user’s collection. It offers a unique and fun experience, with strong hits that take things beyond a regular percolator bong.

When picking a gravity bong, keep these key points in mind:

  • Materials and build quality – Spending a bit more on a well-made gravity bong pays off. Avoid options under $50, as quality is often lacking at that price. Glass models typically outlast and outperform plastic ones.
  • Ease of use and cleaning – Glass gravity bongs are easier to maintain and keep clean, making them more user-friendly over time.
  • Portability – If you want to use your bong on the go, consider kits like the Gleeb, which include a carrying case for convenience.
  • Get the best price – Check sites like American Marijuana for coupons and deals before you buy to save money.

Once you’ve chosen your gravity bong, relax and enjoy some powerful hits. For those looking for an even stronger experience, trying dab concentrates is a good next step.
