Every cannabis enthusiast comes across a moment where they have either run out of their stuff or don’t have smoking equipment which can be used to consume the beautiful herbs. Whether it is because your friends ditched you at the last moment, or because you’re stuck in a foreign city with just your nugs, or simply because you can’t keep the smoking accessory at your home, these situations call for some creativity and improvisation. So here we are, teaching you how to make a water bottle bong?
Homemade bongs aren’t a new thing! People have been finding ways to make an aesthetically pleasing and dope bong with just a few of the household items. Trust me, with DIY, your creativity is the limit. I have had friends who own a perfectly functional piece of equipment but yet indulge in this homemade stuff because it is more fun. So if you fall in any of these categories, have a look at how you can make a wonderful bong with everyday items.
Before we start, a word of caution for the enthusiastic tokers out there; just remember that we are using a plastic bottle to make it, and it could entail some harmful particles that can find their way into your smoke. Use this method when absolutely nothing works.
Let’s get started, get the creative juices flowing!
THE CLASSIC BONG
If you’re looking for something more like a real bong, then this is it. It doesn’t require too much material or skill, but it does need a little more patience.
For this homemade water bong, you’ll need a water bottle, scissors or a box cutter, an old pen, a metal socket, and tape.
Starting with the plastic pen, you’ll need to take it apart. The only thing you’ll need from the plastic pen is the pen shaft. If you have any other type of small, hollow tube, that will also work.
Next, find a water bottle. A slightly larger bottle might be better, as some people use a 2-liter, but whatever you have on hand will work.
About a third of the way from the bottom of the bottle, cut a small hole with the box cutter or scissors. Try not to split the bottle entirely, but don’t worry if it’s a large hole; you can fix it later.
Take the pen shaft or hollow tube and place it in the hole at a downward angle. If the gap is too big, use tape around the hole to fix it and keep the pen shaft in place.
You’ll need to use a small metal socket that can fit in or over the pen shaft to make the bowl work. A socket is a metal cylinder that attaches to a socket wrench, so you can probably find something like it in a toolbox.
You’ll probably need to seal the socket to the pen shaft with tape. If you don’t have a socket lying around, you can make a makeshift bowl from aluminum foil.
Opposite the side of where the pen shaft is, you’ll need to cut another hole for the carb for proper airflow. Make this hole small enough to be able to cover it with one finger.
Lastly, fill the bottle with water until it covers the opposite end of the pen shaft, load up your cannabis, and you’re ready to go.

How to make a water bottle bong? – Step-by-step Guide
Step 1:

The first step is to create a downstem and bowl for your bottle bong. Now, this may seem like it’s a lot, but trust me, it’s the easiest way to construct a downstem. Start by taking a pen and unscrew all its pieces. Discard the ink refill and the end screw. So now, you just have the body of the pen with its top v-shaped metal screw-on-top.
Get the idea that the body of the pen will be your downstem while the top screw will act as a bowl. Somewhat like shown in the picture.
So to complete the piece, just place the metal screw-on-top upside down, and push it into the pen’s shaft just enough so that is tightly held by it. There you have it!
Step 2:

Coming to the second step of how to make a water bottle bong, this one asks to attach the downstem and bowl that we made, into the bong, i.e, the water bottle.
To begin, make sure your bottle is empty. Discard the cap and drain out any water. If you’re using a soda bottle, make sure none of the sticky residues is left in it.
Now imagine where the downstem and bowl are on a bong, and figure out space on your water bong. It is usually on the bottom of the bottle or the bottom third of it. You have the pen pipe, but to attach it to the bottle, we need to make a hole. Use a lighter and flame the bottom third of the bottle. Once the fire melts off the plastic, you can quickly insert the end of the pen inside it. Make sure the metal screw is outside the bottle, whereas the opposite end is inside.
You might be unsuccessful on your first attempt as the bottle may not have craved an accurately sized hole. You can repeat the process until you have the pen pipe securely attached.
Step 3:
You have placed the pen-pipe, and made a perfect downstem and bowl, but, you still have to secure it. The reason for this is that until the hole and the pipe is tightly secured, you can lose a lot of smoke through the small gaps and render your efforts useless.
To seal the gap, you may use glue, or duct tape to do the job. In my experience, a chewed gum works the best because it just sticks to it.
Step 4:
This step calls for filling water into your bong. Just remember, that you have to fill it to submerge the down end of the pen pipe and not more than that. If you allow the water to reach the meeting point of the pipe and the bottle, it may loosen up the glue.
Step 5:
If you would like to pierce a carb, you can do that using a scissor or a lighter. Make sure you do this on the opposite side from the downstem. It should be a small hole, don’t pierce the scissors too hard into it.
Step 6:
There you have it, the last step of the water bottle bong.
Now pack the bowl (Pen metal screw-on) with your herbs, light it, and use the water bottle mouth as the bong mouthpiece. Inhale and have an awesome DIY smoking session.

We were building these things in the late 70’s. First of all use a plastic bottle with a snap off lid such as a half gal. milk jug or juice bottle, this will make it easier to remove the lid when ready to inhale. Second use a one hitter bowl from an old bong! this is so you don’t spill all of your precious commodity on the floor or in tub water, or burning plastic or foil. put a hole in the lid to fit your bowl careful make hole just big enough to screw bowl into. Next use ice in your tub water for a smoother hit! these are my old school methods. enjoy hope this is helpful for all you younger adults out there!
A metal sprite bottle (to this day I can’t find another one) for the chamber. A pen tube for the stem A brass hose barb for the bowl. A hose ball valve screwed onto the top for a carp. A piece of vinyl tubing near the top as the whip. It’s name is Gordon.
