Gravity Bong: How To Make One

A gravity bong, also known as a “gravity bowl,” is a homemade smoking device that uses the principles of gravity and pressure to pull smoke into a container. It is typically made using a plastic bottle and a larger container, such as a bucket or a sink. There are two main gravity bongs: bucket bongs and waterfall bongs. 

Gravity bongs are known for providing an intense and highly concentrated hit of smoke due to a large amount of smoke pulled into the bottle quickly. This differs from traditional smoking methods, such as a pipe or a joint, where the smoke is inhaled in smaller and more controlled doses.

Step by Step Guide on How to make a Gravity Bong

Here is a step-by-step guide on how to make a bucket gravity bong using household materials:

  1. Gather materials: You will need a plastic bottle (at least 2 litres), a bucket or large container, aluminum foil, scissors, and a drill or a hot needle.
  2. Cut off the bottom of the plastic bottle: Use scissors to cut off the bottom carefully. The cut should be made about 2 inches from the bottom. Be sure to keep the cut piece of plastic, as it will be used later.
  3. Make a bowl in the plastic piece: Take the plastic piece you cut off and use the scissors to make a small bowl on one end. Make sure the bowl is deep enough to hold the cannabis.
  4. Make a hole in the side of the bottle: Use a drill or a hot needle to make a small hole in the side of the bottle. The hole should be made near the top of the bottle but below the cap. This will serve as the carb, which will be used to control the flow of smoke.
  5. Cover the bowl in aluminum foil: Take a small piece and shape it into a bowl. Make sure it fits snugly into the plastic bowl you made in step 3. This will be the actual bowl where you will place the cannabis.
  6. Put it together: Put the plastic bowl with aluminum foil bowl into the hole you made on the side of the bottle; the foil should be facing inside the bottle. Next, fill the larger container (bucket or sink) with water and insert the bottle, cap end down, into the water.
  7. Use it: Place cannabis in the aluminum foil bowl and light it. Slowly pull the bottle out of the water, creating a vacuum. Smoke will be pulled into the bottle. Once the bottle is filled with smoke, remove the cap and inhale the smoke.

It’s important to remember that this is a homemade device and could be potentially dangerous, inhaling harmful chemicals from the plastic. Also, the legality of using a gravity bong may vary depending on location, so check your local laws before using it.

Tips for Using Gravity Bong

  1. Start with a small amount of cannabis: It is best to start with a small amount of cannabis in the bowl and gradually increase the amount as needed. This will help you control the amount of smoke inhaled and prevent overwhelming yourself.
  2. Control the flow of smoke with the carb: On a bucket gravity bong, the carb is a small hole made in the side of the bottle. This hole allows you to control the flow of smoke by covering it with your finger while pulling the bottle out of the water and releasing it when it is full of smoke.
  3. Take slow and steady pulls: When inhaling the smoke, take slow and steady pulls. This will help you control the amount of smoke inhaled and prevent overwhelming yourself.
  4. Take breaks between hits: It’s important to take breaks between hits, especially if you are a beginner or are not used to smoking with a gravity bong. This will allow you to catch your breath and get used to the effects of the smoke.
  5. Use a screen: To prevent any debris or ash from getting into the smoke, you can use a screen on top of the aluminum foil bowl.
  6. Don’t overfill the bottle: It is important not to overfill it with smoke, as it can be overwhelming. It’s better to take a couple of small hits than one big hit.
  7. Be aware of your surroundings: Using a gravity bong can be intense and may cause dizziness or disorientation, so it is essential to use it in a safe and comfortable environment and avoid using it while operating machinery or driving.
  8. Clean your bong: It’s essential to clean your gravity bong after every use to prevent the buildup of resin and bacteria.

Effects of Gravity Bong

Using a gravity bong can produce a much more intense and concentrated hit of smoke compared to other smoking methods, such as a pipe or a joint. This is because the vacuum created by the water and the bottle quickly pulls a large amount of smoke into the container. This can produce a more intense and immediate high, but it can also be overwhelming for some people, especially beginners or those not used to smoking with a gravity bong.

The effects of using a gravity bong can include an intense head rush, increased heart rate, and disorientation. However, these effects can be lower than those produced by other smoking methods and can lead to a stronger and quicker onset of the typical effects of cannabis, such as relaxation, euphoria and altered perception.

It is important to note that the effects of cannabis can vary depending on the strain, dosage and the individual, and inhaling smoke can negatively affect your lungs. Hence, it’s essential to use it in moderation and to be aware of your surroundings and the setting where you are using it.

It is also worth mentioning that using a gravity bong is not recommended for people who are sensitive to smoke or have respiratory problems, as the intense hit of smoke can be harsh on the lungs.

Safety Precautions When Using a Gravity Bong

Safety precautions when using a gravity bong include:

  1. Not using plastic bottles or other materials that can release harmful chemicals when heated: Plastic bottles can release toxic chemicals, such as Bisphenol A (BPA), which can be dangerous when inhaled. Therefore, it’s essential to use glass, metal or ceramic bottles that are safe to heat.
  2. Avoid overheating the material: Overheating the material can cause combustion, releasing harmful chemicals and carcinogens. It’s important to use a low flame and avoid holding it too close to the material.
  3. Using a screen: A screen can help to prevent small particles from entering the smoke, which can be harmful when inhaled.
  4. Not sharing: Sharing a gravity bong can increase the risk of transmitting infections or diseases.
  5. Proper cleaning: Cleaning a gravity bong after each use can help to prevent the buildup of bacteria and other harmful substances.
  6. Consuming in a safe environment: It’s important to consume cannabis in a safe environment, free of distractions and potential hazards.
  7. Being aware of the laws: It’s important to be mindful of the laws of your state and country regarding cannabis use, as well as the possession and use of smoking devices.

By following these safety precautions, you can help to reduce the risk of harm when using a gravity bong.
