How To Make A Gravity Bong

Gravity bongs are a fun alternative to other smoking devices, and offer a unique way to smoke cannabis that you can’t find with any other method.

As the name suggests, they use gravity to pull large amounts of smoke into the chamber, much more than with a regular bong or water pipe.

Best of all, it’s easy to make your own, and you only need a few materials that you probably already have at home.

If you’re interested in making your own gravity bong, then you’ve come to the right place! In this simple guide, we’ll take you through all the steps needed to make your very own gravity bong in just a few minutes.

So what are you waiting for? Let’s get started!

What Is A Gravity Bong?

First things first – what exactly is a gravity bong? If you’ve never encountered one before, you might not know how they work, let alone how to use or make one.

So let’s clear the air and take a look at what these devices actually are.

Gravity bongs are a type of water pipe that pulls smoke into its chamber using (you guessed it!) gravity. They consist of a bottle, typically a plastic one, that is placed into a larger container of water with the smokable held in a bowl.

When the product is lit and the bottle is lifted, the smoke is pulled down into the bottle where it is cooled by the water.

You can then remove the bowl and gently push down, which forces the smoke back out the top of the bottle to be inhaled.

Unlike a regular bong, which relies on a person’s breath to pull smoke through, gravity bongs use changes in air pressure to move the smoke around.

They have become popular due to the larger amounts of smoke that can be pulled in one go, reducing the number of times you need to fill and light a bowl.

They also provide a much stronger high than a one-hitter due to the large amounts of smoke inhaled in one go.

A gravity bong is incredibly easy to make, and you only need a few materials and tools to make your own. So without further ado, here’s how to make a gravity bong!

How To Make A Gravity Bong: A Step-By-Step Guide

Now that you know what a gravity bong is, it’s time to get started on making one. Here we’ll walk you through the easy steps to making your own gravity bong.

1) Gather Your Supplies

First, you need to get all the materials and tools you need. Most of these are common household items that you probably already have. Here’s a list of what to get:

  • A plastic bottle, preferably between 1-2 liters
  • A larger plastic bottle/bucket that the first bottle will fit inside
  • Scissors
  • A piece of foil around 2″x2″

2) Prepare Your Pieces

With your supplies gathered, it’s time to get them ready to use. 

Take the smaller bottle and use the scissors to carefully cut off the bottom. You don’t need to remove too much, only around an inch or so. This will be the main part of the bong that the smoke will go into.

Next, if you’re using another bottle for the water chamber instead of a bucket, cut the top off of it.

You want to leave enough space for the smaller bottle to fit inside comfortably, reaching just slightly under the top of the larger bottle. Don’t worry if the lines are a bit wobbly, this doesn’t have to be perfect.

If you already have a bowl from a regular bong, then you can use this. If not, you can make a makeshift bowl with a piece of foil. Gently mold the foil around your thumb to make a shallow indent.

This will be the bowl itself. 

From there, put it in the mouth of the smaller bottle and gently press down to shape it with the bottle.

Then, using a toothpick or pin, carefully poke 3-4 small holes in the foil for the smoke to go through.

3) Set Up The Bong

Now that your parts are ready, you can set up your gravity bong. Fill the larger bottle/bucket with water, leaving enough room for the smaller bottle to sit inside with a small air pocket at the top.

Place the smaller bottle in the water, and put the bowl in the mouth.

The bottle shouldn’t float on its own, but you may need to hold it down slightly when you’re lighting the bowl to keep it in place.

Having a bit of air left in the bottle is important as this will help generate the pressure needed to pull the smoke through, as well as keeping the bowl (and your product) dry.

4) Light Your Product

From here, you can add your product. Take a small piece of shake or hash and add it to the bowl.

Gently press down to pack it in as you would with the bowl on a bong, not using too much pressure as a firmly-packed bowl won’t burn properly.

Here’s the tricky part – you’ll need to light the bowl while also having enough of a grip of the bottle to lift it up. Hold the bottle around the neck, and use a lighter to start burning the product. 

A longer lighter such as a candle lighter will work best and will keep your hands out of the way.

You’ll only need to hold the flame there for a few seconds, as the oxygen being pulled through will keep your product burning as you go.

 5) Using Your Gravity Bong

Now that you’ve lit your product, begin gently lifting the bottle out of the water.

Don’t go too fast or else you won’t get an even burn; also, avoid pushing down at all as this will push the bowl out of the bottle.

Keep lifting it up until the bottom of the bottle is near (but not above) the surface of the water.

Remove the bowl from the bottle, taking care not to lift the bottle out of the water. Then, place your mouth over the mouth of the bottle, and start slowly pushing down while inhaling.

This will push the smoke out of the bottle and into your lungs. 

Don’t worry if you can’t breathe it all in at once, especially with a larger bottle – if you need to take a pause, simply cover the mouth of the bottle to stop the smoke from escaping.

Because of the amount of smoke you’re breathing in at once, it’s natural to feel the need to cough. Don’t try and hold it in – it’s better to get it out than hold it in.

When you’ve pushed all the smoke out of the bottle, congratulations! You’ve just successfully used a gravity bong for the first time!

Final Thoughts

Gravity bongs are a great way to mix up your smoking session with a new and fun way of smoking. Using a gravity bong will give you a massive hit and is a sure way to get stoned fast.

If you want to mix things up, or simply need a way to smoke in a pinch, then gravity bongs are a great choice for you.

Now that you know how to make your own gravity bong, all that you need to do is try it for yourself. Have fun!
