What Is A Marijuana Gravity Bong?


How To Make A Gravity Bong

I will never forget the first time I was asked ‘do you know what a gravity bong is?’ I was new to the marijuana world (a teenager in the 1990’s), and I was still building my stoner vocabulary. I honestly didn’t know what a gravity bong was, but that of course didn’t stop me from acting like I did to look cool. My older friend was asking me because he wanted me to smoke on one later that day with him. Needless to say, I frantically asked anyone and everyone that I wasn’t too embarrassed to ask throughout the day ‘do you know what a gravity bong is?’ It was only when I actually saw the gravity bong in action that I realized some of my friends knew what they were talking about, while others didn’t.

Fortunately for people new to the marijuana world, there is Google these days. I’m sure that if you are reading this article, chances are you were on Google trying to figure out what a gravity bong is, and/or how to make one. The purpose of this article is to explain what a gravity bong is and how to make one. A gravity bong, or ‘bucket bong’ as I’ve heard it called sometimes, involved a bucket of water, a modified 2 liter bottle (or other plastic bottle that works), and a liter cap that has been modified with a bowl. Below is a picture, courtesy of Wikipedia:

The first thing you will need to make a gravity bong is a bucket. A five gallon bucket is perfect, but really any container that will hold enough water to accommodate a sawed-almost-in-half two liter bottle will work. I’ve seen people use all kinds of jugs, so whatever you can get your hands on that fits the description will work. The next thing you need is a 2 liter bottle. Saw off the bottom of it, as shown in the picture above. Those steps are very straight forward. The part that is much trickier is making the cap and bowl.

I have been far from home many times, making a waterfall, with only one chance to punch a hole that was big enough to push the bottom of the metal pipe bowl through, yet small enough to remain air tight. I have tried to seal the bottle cap and bowl after the fact with just about every product out there, but when the bowl inevitably gets hot, the seal breaks again. If you can make the cap the correct way the right time, it is very beneficial.

the full bowlMy secret is making two very small cross slits using a knife. The slits need to be the diameter of the bottom of the bowl you are trying to punch through, that way it’s enough to push the bowl through it, but not enough to create air problems. You will recycle the bottles after a lot of use (in my case, almost weekly!), but the cap will stay with you forever. I refer to my cap bowl as ‘my precious’ which Ninjasmoker will attest to. It’s great for travel too, because you can get mega high when you get to your hotel, all you need is a new bottle with a hole in the bottom! The bowl cap is easy to hide.

Now that you have constructed the apparatus, it’s time to test it out. Fill the bucket up about 2/3 of the way with water. Push the modified liter bottle with screwed on cap/bowl into the water. You will know if there is too much water, or not enough water, when you do this. There should be an inch or two of air at the top of the liter bottle at the same time that the liter bottle is resting at the bottom of the bucket. Pour out or add more water as needed.

Put the desirable amount of marijuana into the cap, light your lighter, and slowly pull up on the liter. Once the liter is full of smoke (and there is only a couple of inches of the liter left in the water), remove the cap. Make sure to keep the liter steady so you don’t pull the entire liter bottle out of the water, and in the process releasing all of the smoke from the bottle. Once the cap is off, suck out the smoke at a steady pace. Realize that this will cause the liter bottle to either sink back into the water, or pull water back into the liter bottle. You want to time it just right to where you get a solid hit, but not getting water in your mouth. The end result should get you very high. Gravity bongs give you bigger hits with less weed, so it should help you with budgeting your stash.

  1. you should just find someone who blows glass and have them make you a steam roller with the bowl in the middle of the steamroller. It works just the same and your using glass instead

  2. One way to ensure that the bowl/cap assembly is one with integrity is to drill a hole in the cap at the (near) size of the bowl base. (The closer, the better). Any minor gap that exists that would allow air “blow-by” can be addressed with a resin or high-grade glue. Both are resilient to breaking down under the heat produced from both a functional and health standpoint.
    The prohibitive part of this arrangement is having to employ items of size e.g. a two-liter bottle and a bucket or container of water. A bong of any comfortable size gives the same result. The end result is that all smoke is consumed in a way that allows for efficient (and effective) use of the product and there are many ways to do that without employing items of this physical size.
    If pursing this approach for the sake of having a different way of consuming is one’s goal, then that’s fine but once again, there are numerous ways to get the same, efficient results without employing items of this large size.

  3. this is the most commen way to smoke in norway (trondheim) its calld a bucket hit, and it will hit you back in bed
