Gravity bongs can be an excellent smoking choice whether you’re in a pinch and lacking smoking devices or if you simply want to mix up your typical smoking experience. Best of all, gravity bongs are simple to construct and require items that you probably already have laying around the house. This guide provides everything you need to know to make two types of gravity bongs.
What is a gravity bong?
A gravity bong, also referred to as a geeb, geebie, GB, jib, and multiple other terms, is a homemade method of consuming cannabis. Usually made of water bottles, a gravity bong uses air pressure and water to draw smoke out of the device. According to Urban Dictionary, the term “geeb” is simply a shortened version of the word gravity bong. Taking a “geeb” also refers to the act of taking a hit from a gravity bong.
Gravity bong method 1: Bucket bong
The first —and arguably most common — type of gravity bong is known as a bucket bong. Bucket gravity bongs use water to push smoke up and out of an empty bottle and into your lungs.
What You’ll Need
You’ll need to assemble the following to make a bucket bong:
- An empty plastic bottle
- A container filled with water (it needs to be larger than your bottle, as you’ll eventually need to push the bottle down into the container)
- Scissors or box cutter
- Downstem and bowl, or alternatively, aluminum foil
Step 1: Make the bong
Begin by cutting the empty bottle in half. From here on out you will be using only the top half of the bottle, so feel free to toss the bottom half in the recycling bin.

Step 2: Prepare the bowl
You have a couple different options for this step. First, you can use an actual downstem and bowl — the same kind of downstem and bowl combination you’d use in a regular rig. This route requires you to drill a hole into the bottle top of your bottle. Press the downstem into this hole and slide the bowl into the downstem.

Tip: For best results, the hole you drill into the lid should be almost the exact same diameter as your downstem. When the downstem fits into the hole, it should be as airtight a fit as possible.

Alternatively, you can make a DIY bowl using a piece of aluminum foil. For this option, take a square piece of foil and fold in half to give it a bit of thickness. Place the foil over the top of your empty bottle. Gently press down with your fingertip to create a slight depression in the foil. Next, use a paperclip, toothpick, or some other tool to poke several small holes in the foil.
Step 3: Fill a bucket with water
At this point your bong, including downstem and bowl, is all ready to go and it’s time to fill your container with water. Don’t fill it all the way to the top, as you will eventually push the bottle down into the water and you want to avoid spilling.

Step 4: Get ready to smoke
You’re almost ready to spark up and take your first hit. Start the process by packing your bowl with a pinch of ground-up cannabis. Next, hold the geeb in one hand and gently push it down into the water.

Step 5: Light your herb
Keeping the gravity bong submerged in the water, use a lighter or hemp wick to ignite the cannabis. As it produces smoke, slowly and smoothly begin lifting the bottle up out of the water. This creates a vacuum that sucks the smoke down out of the bowl and into the empty bottle.

IMPORTANT: DO NOT LIFT THE BOTTLE ALL THE WAY OUT OF THE WATER OR YOU’LL LOSE ALL YOUR SMOKE!
Lift the bottle up enough that it pulls all the smoke down into the bottle but does not fully emerge from the liquid.
Step 6: Inhale
With the bottle now full of smoke, remove the downstem and bowl and place your mouth over the bottle opening. Gently and slowly push the bottle back down into the water. This will force the smoke up out of the bottle and into your lungs. If you don’t want to clear the entire bottle at once, continue holding it in the water and put the downstem/bowl back on top to trap the smoke.

Gravity bong method 2: Waterfall bong
The waterfall bong is a slightly simpler method requiring fewer components. Here’s how to make and use a waterfall gravity bong.
What You’ll Need
To make a waterfall geeb, you will need the following:
- Empty plastic water bottle
- Scissors or box cutter
- Downstem and bowl, or alternatively, aluminum foil
Step 1: Make your waterfall gravity bong
Begin by cutting a small hole in the bottom of the plastic bottle. It should be large enough to allow the liquid to flow out of easily, but small enough to cover with your finger.
Step 2: Prepare the bowl
As with the bucket bong version, you have two options to create a bowl for your geeb. To use an actual downstem and bowl, you will need to drill a hole into the lid of your bottle. Press the downstem into this hole then slide the bowl into the downstem. Again, the hole you drill into the lid should be almost the exact same diameter as your downstem to keep things airtight.
You can make a bowl using a piece of aluminum foil. Fold a square piece of foil and place it over the top of the empty bottle. Gently press down with your fingertips to create a slight bowl shape and use a paperclip, toothpick, or some other tool to poke several small holes in the foil.
Step 3: Fill the bottle with water
Remove the downstem/bowl combination and put your finger over the hole in the bottom of the bottle. Now fill the bottle with water.
Step 4: Get ready to smoke
Hold your finger over the hole in the bottle to avoid spilling. Now, put your downstem/bowl combination back onto the top of the bottle and pack it with a pinch of ground-up marijuana.
Step 5: Fill the bottle with cannabis smoke
Ignite the cannabis. As it smokes, remove your finger from the hole in the bottom of the bottle and let the water rush out of the bottle. As the water pours out of the bottle, the smoke gets pulled down out of the bowl and into the bottle.
Step 6: Take a hit
Once the water in the geeb is replaced with smoke, quickly place your finger back over the hole on the bottom of the bottle to trap the smoke. When you’re ready to take a hit from your new piece, simply remove the downstem and bowl, place your mouth over the opening, remove your finger from the hole in the bottom and inhale.
If you’d rather not clear the entire bottle at one time, put the downstem/bowl combination back on top of the bottle and cover the hole in the bottom with your finger. This traps the remaining smoke inside the bottle. You can also cover the hole in the bottom of the bottle with a piece of tape to not constantly hold your finger in place.
When you’re ready for more, remove the downstem and bowl, position your mouth over the opening, remove your finger or tape from the hole in the bottom of the geeb, and inhale. Repeat the entire process until you clear the chamber.How to make a gravity bong Copy article link to clipboard. Link copied to clipboard. Contents What is a gravity bong?

What is a gravity bong and how do you make one?
A gravity bong, also known as a geeb, is a cannabis consumption method that uses two empty plastic bottles to funnel smoke through water and push it into the consumer’s lungs. Gravity bongs work by submerging a small bottle with a bowl of cannabis on top in a larger bottle or bucket of water. While lighting the cannabis, slowly draw the bottle out of the water to fill with smoke from the burning cannabis. Unscrew the lid, put your mouth over the bottle’s opening, and push the bottle down to let gravity propel the cannabis smoke into your lungs. Voila!
Do gravity bongs get you higher?
The short answer is yes. Gravity bongs force heavily concentrated smoke into your lungs, filling them to capacity beyond the average hit from a pipe or joint. When you inhale the contents of the smoky bottle into your lungs, you are essentially breathing in the smoke from an entire bowl of cannabis in one go. For this reason, gravity bongs are certainly not for the faint of heart. A tried-and-true method of old school cannabis consumers, it delivers a powerful hit of THC that may be too much for an inexperienced cannabis beginner.
However, if you’re looking for a bit of nostalgia and feel like getting crafty with your cannabis consumption, here’s a handy guide to creating your own gravity bong using a few everyday household objects. (Disclaimer: Inhaling combustible materials from a plastic smoking device may be hazardous to your health. Proceed at your own discretion!)
Are gravity bongs worth making or buying?
If you’re new to cannabis or have a low tolerance, you probably don’t want to start with a gravity bong. But for intermediate to advanced consumers, making a gravity bong is a fun, easy DIY project that ensures a fast delivery of your favorite strain. Not the crafty type? You can buy gravity bongs to add to your collection of hardware and bust one out whenever you want a unique and potent smoke session.
Are water bottles safe to use?
Many homemade bongs or smoking devices are made using single-use plastic bottles, which contain PETE or PET (polyethylene terephthalate) that can release chemicals when heated (like how the water from a bottle that’s been left in a hot car can taste odd). You may pull these chemicals into your lungs when applying heat to your gravity bong.
Research is still being conducted on what sort of impact this type of exposure may have on your health. Many cannabis consumers prefer to use glass or silicone smoking devices and avoid plastic as a precaution. If you choose to make homemade gravity bongs and other smoking devices out of plastic materials, be aware of the risks and proceed with caution.
How to make a homemade gravity bong
First, gather the following items:
- Plastic bottle (any size, but 16-20 oz is ideal)
- Bucket or 2-liter plastic bottle
- Aluminum foil
- Box cutter or sharp knife
- Poking device
- Cannabis strains of your choice (at least one gram)
Gravity bongs can be a bit intimidating if you don’t know where to start, but the procedure is more straightforward than you might imagine. It just requires a little ingenuity, some creative efforts, and the determination to make it work, and in less than 10 minutes you can construct your very own gravity bong using materials you probably already have at home.
Step 1: Cut the smaller bottle
Use your box cutter to cut the bottom off your smaller bottle. The more of the bottle that remains, the larger the hit you’ll receive, so be careful not to trim too much off the bottom of the bottle.
Step 2: Cut the larger bottle
Cut the bottom off your larger 2-liter bottle and fill it with water. If you’re using a bucket, fill your bucket with water.
Step 3: Make a hole in the bottle cap
Unscrew the cap to your smaller bottle and use your box cutter or scissors to make a hole in the bottle cap. It should be big enough to draw air through, but not so big that the foil (and cannabis) will fall through into the water.
Step 4: Shape the foil bowl
Wrap the cap in aluminum foil, shaping the foil to create a small “bowl” divot for your cannabis. You can shape the bowl to be as deep as you’d like, and the foil will keep your cannabis from falling into the water below. You may need to cut off excess foil and shape it to avoid spilling cannabis. Health hack: if you’re looking to spare your lungs, try this metal bowl piece specifically designed to be used for gravity bongs.
Step 5: Poke holes in foil
Use your sharp poking tool to make holes in the aluminum foil. Be careful not to rip the foil! You’ll need about 3-5 holes for proper ventilation.
Step 6: Load cannabis in bottle cap
Load cannabis strains of your choice into the foil-wrapped bottle cap, but don’t screw the cap on yet.
Step 7: Submerge small water bottle
Here’s the tricky part: Submerge the smaller bottle in the filled bottom half of the larger bottle (or bucket) until just the cap remains above water. Carefully screw the foil-wrapped bottle cap back onto the bottle.
Step 8: Light your cannabis
Light the cannabis and slowly pull the smaller bottle upwards out of the water while the bottle fills with smoke. If the bottle doesn’t fill with smoke, you may need to check and make sure that your cap is fully screwed on, and that there are no holes or gaps in the side of the bottle. Any leaks could compromise your gravity bong, and some trial and error may be required before your first successful attempt at a functional device.
Step 9: Unscrew the cap
Once your bottle is filled with smoke, carefully unscrew the cap and put your mouth over the bottle opening.
Step 10: Push the bottle into the water
Gently push the bottle back into the water. As the water enters the bottle, the smoke will be pushed into your lungs.
The cannabis smoke will be cooler, having been filtered through the water, but it will deliver a powerful hit of THC. For best effects, prepare yourself and don’t force yourself to inhale too much smoke. This has the potential to make even the most veteran of cannabis consumers cough, so proceed with caution!
How often does the foil in your gravity bong need to be changed?
You can reuse the foil in your gravity bong. Don’t worry about changing it unless you rip the foil or if the holes get clogged and prevent adequate ventilation, at which point you should swap it out with some new foil.Find out what a gravity bong is, how it works, and follow our easy steps to make your own homemade gravity bong from a water bottle. ]]>
