Homemade Bong: Complete DIY Guide

Ever wonder how in the heck can you create your own bong? Fortunately, making a bong from scratch is easy when you know how.

Homemade Bong: The Highlights

  • If you want to make a cheap throwaway bong, sturdy produce and plastic containers are good bets
  • It is highly recommended that you gather as many supplies as possible because you will likely make mistakes when first trying to create a bong
  • Make sure your downstem hole is airtight in order to maximize your smoking experience
  • A plastic bottle, glass bowl, and a pen tube are perfect materials to craft a homemade bong
  • Avoid tape and similar types of adhesive, messy/juicy fruits, and plastic bowls, and anything aluminum (Aluminum foil can be used, but it gives off a harmful fume when burned)

The Basic Components Of A Homemade Bong

If you are a cannabis connoisseur, then you have probably thought, “Hey, it would be cool to create my very own bong.” 

 Well, you certainly can do that! Constructing a homemade bong isn’t as difficult as you think. So no, you don’t have to be MacGyver or Bob The Builder to create one.

The following pieces are necessary to make a homemade bong:

  • Bowl
  • Chamber
  • Mouthpiece (on occasion)
  • Downstem

It is best to use certain materials to construct each piece of the bong. You probably have some of these pieces right now in your home. If you want to make a cheap throwaway bong, plastic containers and sturdy produce are feasible options. This includes:

They work well because they hold their shape throughout the entire process.

Steer clear of juicy or mushy produce.  While bananas and oranges offer superb flavor, they lack cleanliness, particularly if you’re passing the bong around a smoke circle.

Also, it is highly recommended that you gather as many supplies as possible. You may experience a few trial and error sessions before you successfully create a homemade bong.


To begin construction of a homemade bong, you need to create a chamber. Here are the following materials you can use to create one:

  • Plastic bottle
  • Cucumber
  • Aluminum can
  • Carrot
  • Apple
  • Pumpkin
  • Any type of carton, canister, or tube-like object

Now that you created a chamber, it is time to construct a downstem.

The first step is to make a downstem hole. This hole is where the smoke enters the chamber from the bowl and stem. So make sure that you make a super tight hole around the stem to make a quality bong.

Make a 1/8 to 1/4 inch hole near the bottom of the chamber you’ve chosen from above; the hole should around 2-inches away from the bottom.

Next, you want to make a tube for the downstem. Once you choose a material, place it in the downstem hole. One of the following materials can be used to do so:

  • A true stem
  • Small metal pipe
  • Pen tube

Regardless of which material you choose, make sure that you place it a positive angle so it doesn’t wet your cannabis and mess up the sesh. And please make sure the hole is airtight. This ensures that you maximize your smoking experience with your homemade bong.

Not making the hole airtight will result in smoke exiting the bong from the wrong places, ruining the entire cannabis effect.


Now that you have the downstem fully assembled, it is time to add a bowl. You can use a glass bowl and place it a the top or end of the tube.

If you don’t have any glass bowls around, then you have to create one yourself. Attach rolling papers or even aluminum foil, though it’s not recommended because it gives off toxic fumes when burned.

Next, you want to add water to your homemade bong until the tube is submerged a little under one inch. Be careful with this as too much water will ruin the marijuana.

Too much water diminishes your smoking experience because it reduces the amount of smoke in the chamber.

How To Make A Homemade Bong DYI

Now that you get the gist of making a homemade bong, let’s break it down step by step.

Choosing The Right Chamber Material

To beginning stages of a homemade bong is creating a chamber. While the other materials are useful, perhaps the easiest (and simplest) way to create a bong is using a plastic bottle.

While any kind of plastic bottle will work, please note that the bigger the bottle, the higher the effect you will get from the cannabis. (And you don’t need the bottle cap)

Making The Downstem Hole

Now, it’s time to create the downstem hole.

Poke a hole just below the neck of the plastic bottle to make the carb, in which is the hole you cover with your finger and then let go of so you can inhale the smoke coming from the bottle.

Be sure to create a large enough hole so that air can flow through it effortlessly, but not too big where your finger can’t cover it.

You can use any sharp tool to make the hole using tools such as a:

  • knife
  • straightened-out paperclip
  • pen

Choosing The Perfect Downstem Tube

You can either use a small metal pipe, a pen tube (in which you may have to hollow yourself) or a true stem. After you choose which material you will use, place it in the downstem hole.

Making Everything Airtight

Make sure that your hole is completely airtight. This ensures that you maximize your smoking experience with your homemade bong. So how do you know if it’s airtight good enough?

Conduct the following test to see: Put your hand near or over the seal and blow through the mouthpiece.

Do you feel air coming through? If yes, it’s not tight enough, which means that you may need to attach a rubber stopper to fully seal it.

Picking Out The Bowl

You could create a homemade bowl. But the easiest way is to use a glass bowl.

Adding Water

Fill up the plastic bottle ¼ of the way with water.

Again, do not fill up higher than an inch or you will reduce the quality of your smoking experience because it reduces the amount of smoke in the chamber when you inhale.

Remember The Clearing Hole

It is essentially another name for the carb.  The clearing hole makes sure that not too much smoke enters the chamber, which prevents any oxygen from entering. This will severely hamper the toking experience.

The clearing hole should be pushed with a pen or paper clip about halfway (or slightly lower) down the chamber of your homemade bong.

Test And Enjoy

Now it’s time for the step you have been waiting for! Simply load up your preferred strain of marijuana in the bowl, cover the clearing hole with your finger – and start toking!

Common Setbacks And Concerns

Here are some common issues that you may encounter:

Don’t Use Straws

Please don’t a plastic straw for a pipe! It is not resilient enough to be a pipe and the plastic elicits toxic fumes.

Use A Proper Bowl

Using a plastic bowl (or worse…an aluminum bowl) is not a good idea. These type of bowls will possibly burn your throat, damage your lungs, and give off harmful fumes.

A glass bowl is the best way to go.

Avoid Juicy Fruit

Avoid meshy, juicy fruits such as bananas, kiwis, and oranges. Bananas are too meshy and won’t hold up well to a flame.  Kiwis and oranges are too juicy to be properly toked.

Don’t Use Tape

Try not to use duck tape or any other kinds of adhesive material. They may produce harmful vapors when they are being burned.

Enjoy Your Homemade Bong 

As you can see, it is not extremely difficult to craft a homemade bong. All you really need are basic materials  (plastic bottle, glass bowl, and a pen tube) to create one.

Once you get the gist of making homemade bongs, you can get extra creative as other people have done so across the world. Regardless of the method that you choose to make a bong, just be safe and toke wisely.
