How to Make a Bong Without Foil

A bong is a device that is used to smoke herb or tobacco by filtering the smoke through water. Bongs can be made from various materials, such as glass, plastic, metal, or wood. However, some of these materials may not be readily available or safe to use. For example, using aluminum foil as a bowl for your bong can release harmful chemicals when heated. Therefore, it is better to avoid using foil and opt for other alternatives instead.

In this blog post, we will show you how to make a bong without foil using some simple and cheap supplies that you can find at home or in a nearby store. We will also give you some tips and precautions to make your bong experience more enjoyable and safe. Let’s get started!

Method 1: Making a Plastic Bottle Bong

One of the easiest and most common ways to make a bong without foil is to use a plastic bottle and a pen or a highlighter. Here are the steps you need to follow:

  1. Fill up a plastic bottle ¼ of the way with water. Any kind of plastic bottle will work, but keep in mind that the larger the bottle is, the bigger the bong hits will be. Don’t worry if you don’t have the cap to the bottle—you won’t need it! The water you’re putting in the bottle is what the smoke will filter through when you’re smoking the bong.
  2. Poke a hole just below the neck of the water bottle to make the carb. The carb is the hole you’ll cover with your finger at first and then let go of so you can inhale the smoke in the bottle. Make the hole large enough for air to easily flow through it, but not so big that you won’t be able to cover it with your finger. You can use any sharp tool to make the hole, like a pen, a knife, or a straightened out paperclip. Be careful that you don’t cut yourself or make the hole too big.
  3. Make a second hole slightly above the waterline for the downstem. You’ll put the downstem—the tube with the bowl attached to it—through this hole at an angle so the end inside of the bottle is submerged in the water. Make this hole with the same tool you used to make the first one. Make the hole about the same width as a pen. If it’s any smaller, you may have a hard time pushing the downstem through, and if it’s any larger, the downstem may be too loose.
  4. Use a highlighter and foil to fashion a downstem for the bong. To make the downstem, empty the contents of a highlighter so you’re left with just the hollow plastic tube. You may need to use scissors or pliers to pull the highlighter apart. Then, tear off a small piece of aluminum foil and wrap it around the wide end of the plastic tube. Press the center of the foil down into the tube to make the bowl and poke tiny holes in it so the smoke can get through. If you already have a downstem, you can use that with your plastic bottle bong instead.
  5. Push the open end of the downstem through the bottom hole you made. Angle the downstem downward so the open end inside of the bottle is submerged in the water. When you’re finished inserting the downstem, the bowl should be angled upward on the outside of
    the bottle. If you’re having trouble fitting
    the downstem through
    the hole,
    the hole
    a little bigger
    and try again.
    Be careful not
    to make
    the hole
    too big
    the downstem
    will be too loose.
  6. Pack
    the bowl
    and try out your new bong.
    To use your plastic bottle bong,
    start by covering
    the carb—the hole
    you made at
    the top of
    the bottle—with your finger.
    light up your herb or tobacco in
    the bowl
    and inhale from
    the mouthpiece—the opening at
    the top of
    the bottle.
    the bottle fills up with smoke,
    release your finger from
    the carb and inhale deeply.

Method 2: Making a Gravity Bong

A gravity bong is another type of homemade bong that uses water and air pressure to create suction and pull smoke into a chamber. A gravity bong can produce very potent hits, so be prepared for a strong effect. To make a gravity bong without foil, you will need two plastic bottles of different sizes, a socket for a socket wrench, a thimble, or another circular piece of metal that you can use to hold your smoking substance. Here are the steps you need to follow:

  1. Cut off the bottom of the smaller bottle and the top of the larger bottle. You can use scissors or a knife to do this, but be careful not to cut yourself. The smaller bottle will be the chamber where the smoke will collect, and the larger bottle will be the base that holds the water.
  2. Fill the larger bottle halfway with water. Set the container down and fill it up with tap water. Limit the amount of water so that the container is only half-full. This amount will give you enough gravity to make the bong work without making a mess.
  3. Attach the socket, thimble, or metal piece to the cap of the smaller bottle. You can use duct tape, glue, or rubber bands to secure it in place. Make sure it fits snugly and doesn’t fall off. This will be your bowl for your gravity bong.
  4. Pack the bowl with your herb or tobacco and screw it onto the smaller bottle. Don’t pack it too tightly or you won’t be able to draw air through it.
  5. Submerge the smaller bottle in the water-filled larger bottle. Hold it by the cap and slowly lower it into the water until only the cap is above the waterline. Don’t push it too far or you’ll spill water everywhere.
  6. Light up your bowl and lift up the smaller bottle. As you do this, you’ll see smoke filling up the chamber. Keep lifting until the bottom of the smaller bottle is just above the waterline. Don’t lift it out of the water completely or you’ll lose all the smoke.
  7. Unscrew
    the cap
    and inhale from
    the opening of
    the smaller bottle.
    As you inhale,
    the bottle back down into
    the water
    to force
    the smoke into your lungs.
    Be careful not
    to inhale too fast
    or too much,
    the smoke can be very harsh
    and intense.

Tips and Precautions

Here are some tips and precautions to make your homemade bong experience more enjoyable and safe:

  • Clean your bong regularly to prevent mold, bacteria, and residue buildup. You can use hot water, soap, alcohol, vinegar, or baking soda to clean your bong.
  • Replace your water after each use to keep it fresh and avoid unpleasant smells and tastes.
  • Use a screen or a filter to prevent ash and herb particles from getting into your mouth or lungs. You can use a piece of wire mesh, a coffee filter, a cotton ball, or a piece of cloth as a screen.
  • Be careful when using sharp tools or hot materials to make your bong. Wear gloves, goggles, and protective clothing to avoid injuries.
  • Be responsible when using your bong. Don’t smoke more than you can handle, don’t drive or operate machinery while high, and don’t share your bong with others without sanitizing it first.


Making a bong without foil is easy and cheap if you have some basic supplies at home or in a nearby store. You can use a plastic bottle and a pen or a highlighter to make a simple bong, or you can use two plastic bottles and a socket or a thimble to make a gravity bong. Both methods will allow you to enjoy your herb or tobacco without exposing yourself to harmful chemicals from foil. However, you should also follow some tips and precautions to make your homemade bong experience more enjoyable and safe. We hope this blog post has helped you learn how to make a bong without foil. Happy smoking!
