What are the best materials and tools to use for making a glass bong at home?


A glass bong is a device that allows you to smoke herb or tobacco through water filtration, resulting in a smoother and cooler experience. Glass bongs are popular among smokers because they are durable, easy to clean, and come in various shapes and sizes. However, glass bongs can also be expensive and hard to find, especially if you live in an area where they are illegal or frowned upon. Fortunately, you can make your own glass bong at home using some cheap, basic supplies and some creativity. In this blog post, we will show you how to make a glass bong in 8 simple steps, as well as what materials and tools you will need.

Materials and tools

To make a glass bong at home, you will need the following materials and tools:

  • A piece of glass tubing. This will be the main body of your bong. You can find glass tubing online or at a local hardware store. The length and diameter of the tubing will depend on how big you want your bong to be, but a good rule of thumb is to choose a tube that is about 12 inches long and 1 inch wide.
  • A glass bottle. This will be the base of your bong. You can use any kind of glass bottle, but make sure it has a wide mouth and a flat bottom. A wine bottle or a liquor bottle works well.
  • A propane torch. This will be used to heat and shape the glass tubing. You can buy a propane torch online or at a local hardware store.
  • A working surface. This will be where you will do the glassblowing. You will need a flat, heat-resistant surface that can withstand high temperatures. A metal table or a ceramic tile works well.
  • A pair of pliers. This will be used to hold and bend the glass tubing.
  • A drill and a diamond drill bit. This will be used to make holes in the glass bottle and the glass tubing. You will need a 3/4 inch diamond drill bit to drill through the glass.
  • A rubber grommet. This will be used to seal the hole where the glass tubing meets the glass bottle. You will need a rubber grommet with an outside diameter of 31/32 inch, an inner diameter of 1/2 inch, and a 3/4 inch groove.
  • A downstem and a bowl. These will be used to hold and smoke the herb or tobacco. You can use any downstem and bowl that fit your glass tubing, or you can make your own using a highlighter and some aluminum foil.


Once you have gathered all the materials and tools, you can follow these steps to make your glass bong:

  1. Cut the glass tubing to the desired length. Use a pair of pliers to score the glass tubing where you want to cut it, then snap it off carefully. You can also use a saw or a file to smooth out the edges.
  2. Heat one end of the glass tubing with the propane torch until it glows red. Then, blow into the other end of the tube to create a bubble-like shape. This will be the mouthpiece of your bong.
  3. Heat another spot on the glass tubing about 4 inches below the mouthpiece until it glows red. Then, use the pliers to bend the tube at an angle of about 45 degrees. This will be the joint where the downstem will go.
  4. Drill a hole in the side of the glass bottle near the bottom using the drill and the diamond drill bit. Make sure the hole is large enough for the glass tubing to fit through snugly.
  5. Insert the rubber grommet into the hole in the bottle. Then, insert one end of the glass tubing through the grommet until it reaches about halfway into the bottle. The joint should be facing upward on the outside of the bottle.
  6. Fill up the bottle with water until it covers about an inch of the glass tubing inside.
  7. Attach the downstem and bowl to the joint on the outside of the bottle. If you are using a highlighter and foil, empty out the contents of the highlighter and wrap some foil around one end to create a bowl. Poke some holes in the foil for airflow.
  8. Pack some herb or tobacco into the bowl and light it up. Cover the hole in the bottle with your finger and inhale from the mouthpiece. When you are ready to take a hit, release your finger and enjoy!


Making a glass bong at home is not as hard as it may seem. With some basic materials and tools, you can create your own custom bong that will serve you well for a long time. Just remember to be careful when working with glass and heat, and to clean your bong regularly to prevent mold and bacteria growth. Happy smoking!
