How to Make a Water Bottle Bong – A Step by Step Guide


If you are looking for a quick and easy way to enjoy your favorite herb or tobacco, you might want to try making a water bottle bong. A water bottle bong is a simple homemade device that allows you to smoke through water filtration, which can enhance the flavor and smoothness of your smoke. All you need are some basic household items and a few minutes of your time. Here is how to make a water bottle bong in a few simple steps.

What You Will Need

To make a water bottle bong, you will need the following materials:

  • An empty plastic water bottle. Any size will work, but a standard 16.9 ounce bottle is ideal. Remove the cap and the label.
  • A ballpoint pen. You will use this as the downstem, which is the tube that connects the bowl to the water chamber. You will need to take apart the pen and keep only the hollow plastic tube.
  • A metal socket. This is the part that holds the light bulb in a lamp. You will use this as the bowl, which is where you put your herb or tobacco. You can find a socket at any hardware store or online. Make sure it fits snugly into the pen tube.
  • A lighter. You will use this to light your herb or tobacco, but also to help make the hole for the downstem and melt it to the bottle.
  • A needle, pin, toothpick, or other sharp tool. You will use this to poke holes in the bottle for the downstem hole and the carb. The carb is a small hole that you cover with your finger when you inhale and release when you clear the smoke from the bottle.
  • Duct tape and gauze. You will use these to seal any gaps or leaks around the downstem and the carb.
  • Water. You will use this to fill the bottle about a quarter of the way.
  • Your herb or tobacco of choice. You will use this to pack the bowl and enjoy your smoke.

How to Make a Water Bottle Bong

Follow these easy steps to make a water bottle bong.

  1. Make the downstem and bowl. Take apart the ballpoint pen, removing all the components until you are left with only the long empty plastic tube. This becomes the downstem. Insert the metal socket into one end of the pen tube, making sure it fits tightly. This becomes the bowl. If there is any gap between the socket and the tube, you can wrap some gauze around it and secure it with duct tape.
  2. Make the downstem hole. Use your lighter to heat up a small area on the side of the water bottle, just below where the label was. The area should be slightly above the water level when you fill it later. When the plastic is soft, use your needle, pin, toothpick, or other sharp tool to poke a hole through it. The hole should be big enough for the pen tube to fit through, but not too big that it is loose.
  3. Insert the downstem. Push the open end of the pen tube through the hole you just made, at an angle so that it reaches near the bottom of the bottle on the opposite side. The socket end should be sticking out of the bottle, pointing upwards. The pen tube should be submerged in water when you fill it later.
  4. Seal the downstem. Use duct tape and gauze to seal any gaps or leaks around where the pen tube enters the bottle. Make sure there is no air escaping from around the downstem.
  5. Make the carb. Use your needle, pin, toothpick, or other sharp tool to poke another hole on the side of the bottle, slightly above where you made the downstem hole. This hole should be smaller than the downstem hole, and easy to cover with your finger.
  6. Fill with water. Pour some water into the bottle, until it covers about an inch of the pen tube inside. Do not fill it too much or you will get water in your mouth when you smoke.
  7. Pack and light. Grind your herb or tobacco and pack it into the socket bowl. Do not pack it too tightly or you will restrict airflow. Use your lighter to ignite your herb or tobacco while covering the carb with your finger.
  8. Inhale and enjoy. Put your mouth over the opening of the bottle and inhale slowly. You should see the bottle fill up with smoke. When you are ready to clear the smoke, release your finger from the carb and inhale sharply. Repeat as desired.

Tips and Tricks

Here are some tips and tricks to make your water bottle bong experience more enjoyable.

  • Change the water regularly. Dirty water can affect the taste and quality of your smoke. You can also experiment with different liquids, such as juice, tea, or soda, to add some flavor to your smoke.
  • Clean the downstem and bowl. Resin and ash can build up in the downstem and bowl over time, making them clogged and hard to smoke. You can use a pipe cleaner, cotton swab, or paper clip to scrape out any residue. You can also soak them in rubbing alcohol or hot water to dissolve any stubborn gunk.
  • Be careful with the aluminum foil. Aluminum foil can be toxic if used improperly, such as by heating, inhaling, or ingesting it. Make sure you do not burn the foil when you light your herb or tobacco, and do not inhale any bits of foil that may break off. You can also use a metal screen instead of foil for the bowl, or buy a glass bowl online or at a smoke shop.
  • Be creative. You can use different types of bottles, such as soda bottles, juice bottles, or milk jugs, to make different sizes and shapes of bongs. You can also decorate your bong with stickers, paint, or markers to make it more personalized.


Making a water bottle bong is a fun and easy way to smoke your herb or tobacco. It only takes a few minutes and some basic materials that you probably have lying around. Just follow these simple steps and you will have a fully functioning bong in no time. Remember to be safe and responsible when using your water bottle bong, and enjoy!
