Far from embodying the braindead “stoner” stereotype, the cannabis community is actually quite ingenious—especially when it comes to throwing together makeshift smoking devices. The water bottle bong is one of the best examples of this ingenuity.
A water bottle bong is exactly what it sounds like: a bong fashioned out of an old water bottle. A water bottle bong should not be your primary smoking tool. In fact, it should probably not even be a piece you use more than once. Instead, a water bottle bong is a last-ditch effort when you find yourself in a pinch and have no other way to smoke. If you find yourself in this situation, making a water bottle bong will serve as a quick, easy, and incredibly effective solution. Here's everything you need to know to build a water bottle bong from scratch.
What you need to build a water bottle bong
- A plastic water bottle. Use one of the standard 17-ounce bottles, and avoid the smaller ones. You can also use soda bottles, but you'll want to wash out the sticky residue first.
- Scissors, razor blade, or a sharp knife
- A pen, marker, or highlighter that you don't mind taking apart
- A brass or stainless steel mesh screen
- A small brass fitting or metal pipe bowl
- A needle or toothpick
- Water
- A lighter, match, or hemp wick
- Your favorite cannabis strain
Step-by-step instructions to build a water bottle bong
Time needed: 20 minutes
- Prepare the plastic bottle
Find a plastic water bottle; the standard 17-ounce size works best. If you can't find a plastic water bottle, you can also use a soda bottle. Just be sure you take some extra time to clean the inside thoroughly — you don't want all that sticky residue from the soda getting in the way of your smoking experience. Once you've got a clean bottle, remove the wrapper to make it easier to work with.
- Prepare the downstem
Next, you need to make a downstem that can house some sort of bowl. To make a downstem, you'll need to use either a regular ballpoint pen, a marker, or a highlighter. A slightly fatter marker (think the fat Crayola Magic Markers) or a thicker highlighter tend to work the best, but a normal pen is doable, too. Take apart the pen, marker, or highlighter and remove all the insides; you only need the empty cylindrical body of the pen, marker or highlighter. This empty plastic tube will serve as your downstem. Now you need to pair your downstem with a bowl.
- Make a bowl
Skip the aluminum foil — heating foil can release toxic fumes, and you also want to avoid letting direct flame touch the plastic stem itself. Instead, use a small brass fitting or metal pipe bowl that fits snugly over the end of your plastic cylinder. Drop a brass or stainless steel mesh screen inside to hold your herb and prevent pull-through. This keeps all heat contact on metal only, while the plastic tube acts strictly as the stem downstream of the flame. If you already have a metal pipe bowl that fits your cylinder, even better — no hardware store trip required.
- Insert the downstem
Use either scissors, a razor blade, or a knife to cut a small hole in the side of the water bottle, roughly an inch or so below the midway point. You can also use a lighter to melt a hole into the bottle; just don't breathe in the fumes. Make the hole barely big enough for your downstem to fit inside. Once you establish a fit, insert the downstem into the bottle, at a downward angle, so that it almost reaches the bottom of the bottle.
- Make a carb hole
Rotate the bottle 90° from the downstem and make another small hole in the side of the bottle, using whatever method you used in Step 4. This will be your carb hole, so be sure it's in a position that will let you hold the bottle comfortably with your finger placed on top of this new opening.
- Add water
With the downstem inserted down into the bottle, hold the entire device upright and carefully pour in enough water to submerge the bottom of the downstem. Once the bottom of the downstem is underwater, you're all set.
- Pack the bowl
Grind up your bud and gently pack it into your bowl. Seat the bowl over the end of the downstem and get ready to smoke.
- Spark up
To smoke your water bottle bong, use the regular mouth of the bottle as your mouthpiece. Hold the bottle sideways with the downstem and bowl sticking up but away from your face. Place your thumb or finger over the carb hole. Use a lighter, match, or hemp wick to ignite the marijuana. Use your lungs to pull in through the mouthpiece. As you do, the smoke will get sucked down into the bottle and begin bubbling up through the water.
- Clear the bong
When you're ready to take a hit, remove your thumb or finger from the carb hole and pull the smoke up through the bottle and into your lungs.
Why people smoke out of water bottle bongs
The only real reason people smoke out of water bottle bongs is that they have no other — or better — smoking device on hand. A water bottle bong is a stopgap solution, not a tool for regular repeated use. You should only make and smoke out of a water bottle bong when you're in a pinch. Otherwise, use a real glass bong.
Bottom line
Smoking out of a real glass bong will always be a better, safer, cleaner, and more enjoyable way to smoke cannabis, but when you have no other options, go ahead and have fun making a water bottle bong.
