How to Make a Bong Without Foil


A bong is a device that is used to smoke herbs or tobacco by filtering the smoke through water. Bongs can be made from various materials, such as glass, plastic, metal, or ceramic. However, some of these materials may not be readily available or safe to use. For example, foil is often used to make a bowl for a homemade bong, but it 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 provide some tips and precautions to ensure a safe and enjoyable smoking experience.

Method 1: Plastic Bottle Bong

A plastic bottle bong is one of the easiest and most common ways to make a homemade bong. All you need is a plastic bottle, a pen or a highlighter, and some aluminum foil. Here are the steps 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.
  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.
    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 or
    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 slowly lift up
    the bottle as
    the smoke fills it up.
    you’re ready to inhale,
    remove your finger from
    the carb and put your mouth over
    the mouthpiece.
    Breathe in
    the smoke as
    you push down
    the bottle into
    the water.

Method 2: Gravity Bong

A gravity bong is another way to make a homemade bong without foil. A gravity bong uses water and air pressure to create suction and fill up a container with smoke. 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 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 will hold the water.
  2. Make a hole in the cap of the smaller bottle and insert the socket, thimble, or metal piece. The hole should be slightly smaller than the diameter of the socket, thimble, or metal piece, so it fits snugly and doesn’t fall out. This will be the bowl for your gravity bong.
  3. Fill up 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.
  4. Screw the cap with the bowl onto the smaller bottle and submerge it in the water. Make sure that the cap is on tightly and that there are no leaks. Then, slowly lower the smaller bottle into the larger bottle until only the top part of it is above the water.
  5. Pack
    the bowl and light it up.
    Put your herb or tobacco in
    the bowl and light it with a lighter or a match.
    you do this,
    slowly lift up
    the smaller bottle out of
    the water,
    but not completely.
    The smoke will be drawn into
    the bottle as
    the water level drops.
  6. Inhale
    the smoke from
    the smaller bottle.
    you’re ready to inhale,
    the cap and put your mouth over
    the opening of
    the smaller bottle.
    Push down
    the bottle into
    the water as
    you inhale
    the smoke.
    Be careful not
    to push down too hard or too fast,
    or you may get water in your mouth.

Tips and Precautions

  • Always use clean and fresh water for your bong. This will ensure a smoother and cleaner smoke, as well as prevent bacteria and mold from growing in your bong.
  • Replace your foil bowl regularly or use a metal piece instead. Foil can release harmful chemicals when heated, so it is better to avoid using it or change it often. You can also use a metal piece that is safe to heat, such as a socket, a thimble, or a metal screen.
  • Clean your bong after every use. This will prevent resin and tar from building up in your bong and affecting the taste and quality of your smoke. You can use rubbing alcohol, salt, and hot water to clean your bong thoroughly.
  • Be careful when using sharp tools or fire to make your bong. You don’t want to injure yourself or start a fire while making your homemade bong. Always use caution and common sense when handling these items.
  • Enjoy your homemade bong responsibly and moderately. Smoking herbs or tobacco can have various effects on your health and well-being, so make sure you are aware of the risks and benefits before you smoke. Also, respect the laws and regulations regarding smoking in your area and don’t smoke in public places or around minors.


Making a bong without foil is possible and easy with some simple supplies and creativity. You can use plastic bottles, pens, highlighters, sockets, thimbles, or other items to make a homemade bong that works just as well as a store-bought one. However, you should also be careful when making and using your homemade bong, as there are some risks and dangers involved. Always use clean water, replace your foil bowl regularly or use a metal piece instead, clean your bong after every use, be careful when using sharp tools or fire, and enjoy your homemade bong responsibly and moderately.
