What's A Gravity Bong?

A gravity bong, also known affectionately as a geeb, uses two different-sized containers and water to push smoke into your lungs. Gravity and water displacement work hand-in-hand to deliver a smoking experience that packs a punch! A gravity bong is easy to make at home without much preparation.

Fact Or Fiction: Do Gravity Bongs Get You Higher?

In a way, smoking from a gravity bong does in fact get you higher. That’s because it’s a highly concentrated amount of smoke that gets forced into your lungs – way more than your average hit. It’s like smoking an entire bowl at once. Basically, when you take a hit, you get smacked in the face with a bunch of THC, so be prepared to cough your brains out! Smoking a gravity bong is not for the faint of heart or inexperienced smokers.

Are Gravity Bongs Safe To Use?

Hitting a gravity bong every so often isn’t going to be a problem for your health. However, using it as a regular cannabis consumption method or reusing a bottle could be hazardous! Single-use plastic bottles contain chemicals that are released when heated, and thus can be pulled into your lungs when you hit your gravity bong. These chemicals can be dangerous to inhale. Tossing your gravity bong (or recycling it!) after use is the best way to avoid inhaling harmful chemicals.

Types Of Gravity Bongs

There are two main methods to make a gravity bong: using a bucket or making a waterfall gravity bong. Both are super easy to construct, you probably have the materials at home already, and it only takes 5-10 minutes to get set up. One method isn’t necessarily better than the other – try both and see which you prefer!

How To Make A Bucket Gravity Bong

You don’t need much to get started! You’ll need:

  • Something sharp, like box cutters or scissors

Now, when you have all the equipment ready, it’s time to assemble our smoking device.

Step 1: Prepare Your Bottle

Cut off the bottom of the bottle you’ll be using for your gravity bong. The bigger the bottle, the more smoke it can hold.

Step 2: Bucket Prep

Take a bucket or a larger bottle with the top cut off. Fill the bucket with enough water that the smaller bottle will be mostly submerged, leaving enough space for some air at the top of the small bottle.

Step 3: Making The Bowl

Form a bowl with some aluminum foil. Shape it so that it tightly seals around the top of the bottle, but can be easily removed later. Poke three or four little holes at the bottom of this makeshift gravity bong bowl for airflow.

Step 4: Submerge The Bottle

Be careful here! Submerge the bottle in the bucket filled with water, making sure that the top where the bowl will go is safely above water.

Step 5: Pack The Bowl

Put the bowl on the top of the bottle and load it up with your favorite strain. Now you’re ready to blast off!

How To Use A Bucket Gravity Bong

Make sure that the bottom of the bottle stays underwater throughout the process, and avoid getting your bowl of weed wet!

Step 1: Light The Bowl

Light the cannabis and lift the bottle slowly upward. The chamber will fill with smoke and the bowl of weed will burn up. Make sure to keep the very bottom of the bottle underwater so you don’t lose all that precious smoke!

Step 2: Remove The Bowl

Carefully remove the aluminum foil bowl off the top of the bottle. Put your mouth over the opening and prepare yourself for a huge hit.

Step 3: Take That Hit

Brace yourself! Push the bottle back into the water and inhale. As the water displaces the smoke in the bottle, the smoke will be pushed deep into your lungs.

How To Make A Waterfall Gravity Bong

Another method is the “waterfall” gravity bong, aptly named for the gushing water that occurs when you light the bowl. This method truly uses gravity to do all the work, as the water rushes out the hole in the bottom of the bottle while pulling in the smoke from the burning bowl on top.

Necessary Materials

To make a gravity bong, waterfall-style, you only need:

  • Something sharp, like box cutters or scissors
  • A large plastic bottle (2 liters is good)
  • Aluminum foil
  • Something to poke with, like a thumbtack

If making a bucket gravity bong seemed easy, making a waterfall one will be even easier! Get the equipment ready and you’ll be done in no time.

Step 1: Prepare Your Bowl

Make an aluminum foil bowl like before by poking three or four holes into the bottom of the bowl to allow the smoke to enter the bottle. Fill it up with weed and set it aside for later.

Step 2: Prepare Your Bottle

You’re going to need only one plastic bottle for this method, preferably a large 1 or 2-liter bottle. Take your knife or scissors and cut a carb hole toward the bottom of the bottle, small enough to cover with one finger.

How To Use A Waterfall Gravity Bong

Before you get started, make sure you’re in a spot where things can get wet! You can use your waterfall bong with a bucket underneath to catch the water, over the kitchen sink, or out in your garden. You want to avoid a puddle in the living room!

Step 1: Fill With Water

Fill your bottle with water, leaving some space at the top (5cm, or 2 inches), and keep your finger over the carb. If you don’t, you’ll spill water everywhere before it’s time!

Step 2: Light It Up

Things are about to get wet! Attach your bowl to the top of the water bottle bong. Let go of the carb hole and light the bowl as the water flows out. The bottle will fill up with smoke. Place your finger back over the carb hole after the water drains out to keep the smoke from leaving.

Step 3: Hit That Bong

It’s time to take a rip! Pop the bowl off the top of the bottle bong, let go of the carb, and start sucking!

What is a Gravity Bong?

A gravity bong is a method of consuming smokable substances such as cannabis. A lung uses similar equipment but instead of water draws the smoke by removing a compacted plastic bag or similar from the chamber. It uses a number of simple items like water bottles and aluminum foil to create a bong that uses gravity instead of your lungs to collect smoke inside its chamber.

How to Use a Gravity Bong?

To use a gravity bong, you need to light the bowl of flower attached to the smaller container while raising it partially above the water (while still keeping it in the water). This creates a vacuum sucking the smoke out of the bowl and filling the chamber with it.
