Is your bong currently out of commission? Not to worry; with just an empty water bottle and a little aluminum foil, you’ll be back in business. We’ve put together an easy, step-by-step guide to help you make a water bottle bong of your very own. Interested in making a water pipe? We've got you covered there, too—scroll down the second section for a handy tutorial.

Method 1 of 2:

Making a Basic Water Bottle Bong

1
Obtain a bottle. You will want to use a bottle that is just the right size for bong-making purposes. A standard 16.9 ounce plastic water bottle should do the trick.
- Water bottles are better than soda bottles because they won’t leave any sticky residue.
- You can remove the label from the bottle, if you want.
- You don’t have to leave any water in the bottle. However, if you want the bong to stand upright, you can leave some in to weigh it down.
- This is not a traditional bong, because it does not force the smoke through the water; however, it can be made quickly and easily.
2
Remove the lid. Set it aside. You will not need it.

Tear off a small piece of aluminum foil. This piece will serve as the bowl. It should be approximately 2.5 inches by 2.5 inches (5cm by 5 cm). You should use thick or “heavy duty” aluminum foil for best results.
- If you only have lightweight aluminum foil, fold it over to make it thicker before forming a 2.5 inch by 2.5 inch square.
- The piece of aluminum foil should be large enough to cover the mouth of the bottle and fold over the edges. Look at your bottle; if 2.5 inches by 2.5 inches doesn’t seem large enough, tear off a larger piece of aluminum foil.
4
Apply the foil. Wrap the edges of the aluminum foil around the top of the open water bottle. Press your thumb down to extend the aluminum foil into the center of the opening. It should form a depressed bowl shape in the top of the water bottle.
- Make the bowl depression large enough to contain your herb, but don’t push down so hard that you tear the aluminum foil.
- Aluminum can be toxic if used improperly, such as by heating, inhaling, or ingesting it.^{[1]

Poke holes in the aluminum foil bowl. 5 or 6 holes are probably adequate. Use a needle, straight pin, toothpick, or other slender object to poke the holes.
- Make sure that the holes are far enough apart that they do not break the bowl.
- Be careful not to poke holes so large that they break the bowl.
6
Punch a hole in the side of the bottle. Poke another hole into the outside portion of the water bottle, just above where the label stops. This is where you will need to place your mouth.
- Don’t try to make the hole too big. Gently poke a hole with your needle or straight pin, then wiggle it around a bit to make the hole a little bigger.
7
Make the side hole bigger with a pair of scissors. Make it approximately 1 inch (2.5cm) in diameter to start. Be careful not to rip the bottle; press down on the hole to indent the plastic slightly, then gently enlarge the hole.
- Start by making the hole a little on the small side. You can always enlarge it later if you need to, but you can’t make it smaller.
8
Pack the bowl. Simply place some of your favorite herb in the aluminum foil bowl. Don’t overdo it; you can always add more later, but you don’t want it spilling over the sides.
- If pieces of your herb fall through the bowl, then the holes you punched are too large. Take the aluminum foil off and try again, this time making smaller holes.
9
Smoke. Cover the hole on the side with your mouth. Light the bowl and let the smoke fill the water bottle bong.
10
Inhale gently. As you light the bowl and smoke fills the water bottle, set down the lighter and gently inhale the smoke in the bottle.

Making a Water Pipe

1
Obtain a bottle.^{[3]

Research source} Some people like to use a two-liter bottle, but a standard 16.9 ounce water bottle can also work just fine.
- Remove the lid from the bottle and discard it.
2
Take apart a plastic pen.^{[4]

Research source} You will need the pen shaft to work as a smoke shaft. Any plastic pen that can be taken apart to leave a hollow cylinder will work.
3
Cut a hole in the side of the bottle.^{[5]

Research source} Using scissors or another tool, gently poke a small hole (just large enough to insert the pen shaft) in the side of the bottle, approximately 1/3 the distance from the bottom. Your pen shaft will extend at an angle into the water.
4
Insert the pen shaft into the hole.^{[6]

Research source} Test the size of the hole by inserting the pen in the hole at a downward angle. If the hole is too big, it will be hard to get a tight seal.
- If it turns out that your hole is too big, you can still salvage the bong. Just place pieces of tape where the pen shaft meets the bottle to make a tighter seal.
5
Pierce a carb into the bottle. On the opposite side of the bottle, make another small hole (about the size of a pencil eraser).^{[7]

6
Attach a bowl. Affix a metal socket to the outside end of the pen shaft. Use another few layers of duct tape to make a seal. The socket is your bowl.
- You can use any sort of metal socket that is the right size. Look around your house for a suitable object. If you can’t find anything, visit a hardware store, where you’ll find lots of possibilities.
7
Fill the bong with water. Pour water from the top of the bottle into the bottom of the bong. Fill it approximately 1/5 full.
8
Pack the bowl. Simply place some of your favorite herb in the metal socket bowl. Don’t overdo it; you can always add more later, but you don’t want it spilling over the sides.
9
Position the bong. Place your mouth at the top of the bottle, where the lid was. Tip the bong so that the bowl is facing away from your body.
10
Light the bowl. Using a lighter, ignite your herb and begin to suck in slowly to force the smoke through the water. Make sure to place a finger over the carb hole while doing this.
11
Smoke. Set the lighter down when the bottle is filled with smoke. Remove your finger from the carb hole. Suck the smoke in deeply through the top of the bottle.
