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 hit. 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 a little bit of 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. You can buy this online or at a local hardware store. The length and diameter of the tubing will depend on the size of the bong you want to create. A good rule of thumb is to choose a tubing that is about 1 inch (2.5 cm) in diameter and 12 inches (30 cm) in length.
  • A glass bottle. You can use any kind of glass bottle, but keep in mind that the larger the bottle is, the bigger the bong hits will be. You also want to choose a bottle that has a flat bottom and a narrow neck, such as a wine bottle or a soda bottle.
  • A propane torch. You will need this to heat and shape the glass tubing. You can buy this online or at a local hardware store.
  • A working surface. You will need a flat and heat-resistant surface to work on, such as a metal tray or a wooden board.
  • A drill and a 3/4 inch (1.9 cm) diamond drill bit. You will need this to make a hole in the bottle for the downstem. You can buy this online or at a local hardware store.
  • A rubber grommet. You will need this to seal the hole in the bottle and secure the downstem. You can buy this online or at a local hardware store. You will need a rubber grommet with the following measurements: an outside diameter of 31/32 inch (2.5 cm), an inner diameter of 1/2 inch (1.3 cm), and a 3/4 inch (1.9 cm) groove.
  • A bowl and a screen. You will need this to hold and burn the herb or tobacco. You can buy this online or at a local head shop. You will need a 14 mm glass bowl and screen that fit your downstem.
  • Water. You will need this to fill the bottle and filter the smoke.


Now that you have all the materials and tools ready, you can follow these steps to make your glass bong:

  1. Cut the glass tubing to the desired length. The length will depend on how deep you want the downstem to go into the water. A good rule of thumb is to measure the distance from the bottom of the bottle to the opposite side of the neck, and cut the tubing about an inch (2.5 cm) shorter than that.
  2. Heat one end of the glass tubing with the propane torch until it glows red. Then, blow into the other end of the tubing to create a bubble-like shape. This will be your bowl.
  3. Let the glass tubing cool down completely before handling it. Then, use a file or sandpaper to smooth out any sharp edges on the bowl and the stem.
  4. Mark a spot on the bottle where you want to drill the hole for the downstem. The spot should be on the upper curve of the body, slightly above the waterline.
  5. Attach the diamond drill bit to your drill and set it to 3/4 of its max speed. Then, hold the bottle under running water and gently push the drill bit against the marked spot until you make a hole.
  6. Insert the rubber grommet into the hole and push it until it fits snugly.
  7. Insert the stem end of the glass tubing into the grommet until it reaches the water inside the bottle.
  8. Place the bowl end of the glass tubing over the grommet and secure it with some tape or glue if needed.

Congratulations, you have made your own glass bong!

To use your glass bong, fill the bowl with some herb or tobacco and place a screen over it. Then, cover the hole on the bottle (the carb) with your finger and light the bowl with a lighter. Inhale from the mouthpiece of the bottle and enjoy!

Remember to clean your glass bong regularly to prevent resin buildup and bacteria growth. You can use warm water and soap, or some rubbing alcohol and salt, to rinse and scrub your bong. You can also replace the water in the bottle after each use.
