How To Make A Gravity Bong

Many long time bong users on hearing about gravity bongs go exploring, and once they find the price tag are reluctant to try this without doing a little experimentation. Making a gravity bong is a bit more complicated than making a traditional bong and you will need several more items to accomplish this. It is possible however to have this type of water pipe completed in under an hour once all the items necessary are acquired. To start out you will need a cleared workspace and some time to concentrate on this do-it-yourself project. The biggest benefit of the gravity bong is the size of the chamber so think big while working on this bong. You will be using a bucket of water, a tub, or even a pool of clear non-treated water such as found in a kiddie pool.

Gathering What You Will Need

Most of the items you will need you can find in a typically household, but a few might require a run to the nearest hardware store. You will need a two-liter plastic bottle, a pair of scissors, a bowl for the pipe. If you don’t have one you can either find one at a head shop, or go to the hardware store and look for materials you can use to fashion a bowl to attach to a tube thus creating a stem and bowl.

Don’t use aluminum for these parts as some have done in the past. The reason for concern is that aluminum contains chemicals and carcinogens that will release when heated. This isn’t something the water can purify out of the smoke, and you don’t want this in your lungs.

Again, the water source can be anything from a large bucket, to a tub or something even bigger. Don’t use anything inflatable however since this will be too near a flame when you burn the material in a bowl.


Start Cutting

The first step is to take one of the bottles and cut off the bottom. If the scissors you have aren’t up to this job then carefully use a knife instead. Next, using the scissors or knife you poke a hole in the top of lid or cap so the bowl can be screwed in, then make sure the bowl fits tightly after threading it through. The cap and bowl are then placed back onto the bottle. Make sure the fit is secure.

Placing the Bottle

You will then take the cap off the bottle. This is important, as the cap must be off when the container is placed in water for the “gravity” part of the bong to work. Snap the cap back on, and holding the lighter to the bowl pull up on the container to draw up the smoke using the water to draw it out. The container should remain in water the entire time, and the pull should last until the material in the bowl starts to glow red just as you see at the end of a cigarette when it’s lighted. Try to hold the container as steady as possible as you do this. The bottle’s bottom should never completely leave the water.

Taking a Draw

When the chamber is full remove the cap and place you mouth over the opening. Push the bottle back into the water just as you are inhaling. As you inhale the draw is a purified and cooled by the water, but it will be denser than the first inhale from most bongs. If this will be the first time using a gravity bong be prepared to cough the first time.

A Few Cautions

The gravity bong isn’t the best choice for those new to smoking marijuana. Even those who have used cigarettes, or water pipes before usually cough and sputter the first time as the smoke in the chamber is more dense than with most other devices. The reason for density is as you press down with the bottle the smoke is pushed upward. This is a purer form of smoking than from cigarettes since the water clears out some of the impurities such as carbon particulates, but it’s denser.  Those who have smoked for years often feel big hits from this type of apparatus in the throat and lungs. Taking smaller shallower draws is recommended until the individual using it feels more comfortable. Because this is denser, those using it should also expect to feel the effects a bit faster.

Caution should be used when lighting the bowl that plastic materials are not too close to flame. As mention earlier foil should not be used to for the bowl’s material, as this is a dangerous product to burn near the mouth and nose. Fumes from aluminum should never be inhaled into the lungs, as this is a safety risk.
