How To Make A Bong Out Of A Can

You might have noticed walking around coming across soda cans that looks like some thing very odd happened to them. They have holes cut into them, and they have an odd, but familiar odor. If you are wondering from these encounters if it’s possible to fashion a bong out of cans the answer is yes, this is possible.

There is a word of caution regarding these devices however, as there’s a problem using aluminum. If you locate soda cans not made from aluminum this is the best choice. Most cans are made from this material, and when you heat aluminum to a high degree it will release inhalable chemicals and metals, which have been linked to serious medical problems such as Alzheimer’s disease and other neurological diseases. When using this metal to make a bong or water pipe you should be aware of this risk, and if you decide to use it, then it’s in your best interest to only use it sparingly.

What You Will Need for a Can Bong

You will actually need two 12-ounce soda cans. These are usually fairly easy to find empty and if not it’s possible to buy two or even a six-pack for fewer than five dollars in the U.S. You Will also needs some adhesive tape, but almost any kind will do. Some prefer masking tape since it’s wider and usually very strong. Also required are a pair of scissors or a small, but sharp knife, water, a can opener and an either a trumpet mouthpiece of glass side to use as the stem and bowl. If you can’t find this last item it’s possible to improvise one out items usually found around the house.

Start with a Clean Can

You will need to clean out any fluid left inside the cans, rinse them out and then dry them. Usually, the cans will dry out in less than hour.

Cut the Ends

Before starting out it’s necessary to cut off the top of one can, and the bottom of another can. To make this clearer the top part of one can, will have the opening you will use as the bong’s mouthpiece, while the other can, serves as the part of the chamber and bottom of the can. The can opener usually works on these cans in same way it would opening a tin container of soup, but if the edges are rough use the scissors or knife to trim these down.

The Base Can

The can that has a bottom with no opening at the top will be the base of the bong. The next step is to create hole for tubing and bowl in this can using the scissors or knife. This shouldn’t be too large a hole, but large enough for your stem to fit through, as otherwise air and smoke will escape around it. Once you fit it through the hole at an angle and can see it doesn’t touch the bottom you are ready to seal around it. To seal around the stem use the adhesive tape. It’s a good idea to build up a few layers to ensure the seal is tight.

More Tape

Tape the two cans together as tightly as possible using several layers for an airtight seal. If possible try to fit the top can into the bottom as much as possible before sealing.


If the tab is still present on the mouthpiece of the top can work this off with your fingers. If there’s a sharp piece of metal still attached cut this part off with the scissors or the knife so you don’t risk cutting yourself.

Pour water through the mouthpiece to the point where the bottom of the base can is covered up above the stem. You want enough of the stem covered to make bubbles, but not so much the water will run back up to the bowl or splash around.

Carb Hole

You could make a small carburetor hole in the base can above the water line if you wish. This isn’t truly necessary, but if you have trouble clearing your water pipe this is a good fix.

Using the Bowl

Place the substance to be smoked in the bowl. This shouldn’t be too dense, but don’t pack it so tightly that pieces will fall through the stem into the can. Light the bowl with a regular lighter or matches as you normal would any water pipe or bong. Using the mouthpiece at the top inhale and use suction to draw the smoke through the stem and into the pipe. At this point you should have a working bong.

Safety Precaution

If you plan on using this can water pipe more than once or so the water at the bottom should be dumped out and the can’s cleaned.
