What Is A Gravity Bong?

GRAV Gravitron Gravity Bong

A gravity bong consists of two containers - a larger one filled with water and a smaller one for cannabis. By lighting the cannabis and lifting the smaller container, smoke is drawn into the chamber. Users inhale by placing their mouth over the opening and pushing the chamber back into the water. Gravity bongs are known for their strong and concentrated smoke inhalation compared to other bongs.

Types Of Gravity Bongs

Gravity bongs come in various types, each offering unique advantages. Now, let's dive into the specifics of each kind.

Bucket Gravity Bong

The bucket gravity bong is a modified design of the gravity bong. It involves a large plastic bottle or bucket filled with water, and inside the water sits a smaller container made from a customised plastic bottle. To use it, simply place the smoking material in a bowl on top of the smaller container. Creating a vacuum by lifting the smaller bottle will draw the smoke into the chamber. Once filled with smoke, remove the bowl and inhale, letting the water push the smoke into your lungs.

Waterfall Gravity Bong

The waterfall gravity bong functions similarly to the bucket bong. Instead of using a smaller bottle to create a vacuum, it has a hole at the base for water drainage. As the water drains out, it creates a vacuum that draws smoke into the bottle. Once the bottle is filled with smoke, the user removes the bowl and inhales, allowing the water to push the smoke into their lungs.

Homemade Gravity Bong

People often create their own plastic gravity bongs using readily available plastic bottles and containers. These DIY options are popular because they can be made with materials found at home. However, caution is necessary when using plastic as heating it can release toxic chemicals.

Glass Gravity Bong

Glass gravity bongs are durable, attractive, and can be bought from trusted online stores that specialise in smoking accessories. The GRAV Large Gravitron Gravity Bong, for instance, offers pure flavour, low maintenance, and a range of design choices to cater to personal preferences.

How Does A Gravity Bong Work?

A gravity bong utilises gravity and air pressure to function. It consists of a water-filled vessel and a smaller container for the smoking substance. To operate, submerge the smaller container in the water, creating a vacuum, and allow gravity to draw the smoke into the bottle. Here's a step-by-step explanation of how it works:

  1. The Setup: The gravity bong consists of a plastic bottle filled with water and a smaller container or bowl for smoking. When the smaller container is submerged in the water, it creates an airtight chamber.
  2. Creating Negative Pressure: Lifting the smaller container upwards creates a vacuum above the water in the larger container, reducing air pressure inside the smaller container and causing the water to rise.
  3. Smoke Generation: Raise the small container to the desired height and light the smoking substance. The substance will burn and produce smoke, filling the empty space inside the container.
  4. Release Of Negative Pressure: Upon releasing the smaller container, negative pressure immediately equalises, forcefully propelling the smoke into the user's lungs as the larger container's water is displaced.

The Science Behind Gravity Bongs

A gravity bong works by utilising gravity and air pressure. When the cannabis in the bowl is ignited and the bottle is lifted, the change in air pressure inside the bottle causes the smoke to be inhaled into the chamber. Then, by pushing the bottle down into the water, the increase in air pressure forces the smoke out of the chamber and into your respiratory system.

The essential scientific principles and laws of physics in action are:

  1. Air Pressure: Boyle's Law states that gas pressure is directly proportional to volume. As the bottle is raised, the enclosed air expands, resulting in decreased pressure. As a result, the smoke is drawn into the bottle.
  2. Gravity: Gravity holds the water down in the container. When you lift the bottle, the pressure drops, allowing the water to rise and fill the bottle, pushing out the air and creating a vacuum. When you push the bottle down again, the water goes back to its original position, increasing the pressure. This pressure pushes the smoke into your lungs.

The gravity bong works by utilising air pressure and gravity to create a vacuum that pulls smoke into the compartment and then expels it when the pressure increases.

Benefits Of Gravity Bongs

How To Make A Gravity Bong

Three GRAV Gravitron Gravity Bongs

Making a DIY gravity bong is simple and straightforward. Here's a concise, step-by-step guide to assist you.

Materials Needed

  • Plastic bottle (2L soft drink bottle or similar size)
  • Large container or bucket
  • Aluminium foil
  • Lighter
  • Ground Cannabis
  • Water

Step 1. Choose Your Bottle

Choose an empty plastic bottle, like a water bottle or a larger soft drink container. The size of the bottle will affect the strength of the hits, so choose accordingly. If you're smoking alone, a smaller bottle will do. But if there are multiple people, opt for a larger bottle. Also, make sure the chosen bottle can fit inside a larger bottle or bucket.

2. Create Bowl

Wrap the gravity bong's mouthpiece with aluminum foil securely, leaving room for easy removal later. Create a few small perforations directly above the mouthpiece to allow smoke to flow into the bottle. Be cautious not to make excessive or oversized holes to avoid any cannabis from accidentally entering the bong.

Step 3. Cut Bottle

Trim the bottom part of the plastic bottle by slicing it about 2.5 - 5 cm above the base. Start with a knife to create an opening and then use scissors to cut in a straight line until the lower section is fully separated. Keep the upper part aside and make sure to recycle the bottom portion responsibly.

Step 4. Make Bong

To do this, get a bigger bucket or plastic container for the water. You can also use a larger plastic bottle and cut off the neck to match the width of the body. Fill the larger container with cold or warm water, leaving a gap of 2.5 - 5cm from the rim.

Step 5. Insert Top Into Container

Place the top bottle inside the bigger water container, ensuring that the open end is facing downwards and the neck and mouthpiece are above the water level. If the water covers the mouthpiece, it means the bottle has been inserted too far.

Step 6. Insert Cannabis

Grind the cannabis cautiously, ensuring it's not too fine. This way, you can prevent smaller particles from slipping through the holes in the aluminum foil. Keep the plastic bottle stable and sprinkle the cannabis onto the foil steadily, avoiding any potential spills.

Step 7. Light Cannabis

To smoke the cannabis, use a lighter to ignite it. Raise the plastic bottle and hold the flame in contact with the cannabis as you lift the bottle. This will create smoke inside the bottle.

Step 8. Raise The Bottle

Raise the bottle until it's just below the water surface without removing it completely. This will fill the entire bottle with smoke.

Step 9. Remove Bowl

Remove the aluminum foil from the bottle. Place your mouth on it and take off the foil. A small amount of smoke may be released, which is normal. Avoid pressing down on the bottle to prevent the escape of all the smoke.

Step 10. Inhale

Press the bottle down gently and inhale slowly. This will release the smoke into your lungs. Take care not to press too quickly as it may result in inhaling excessive smoke. Continue inhaling and pressing until all the smoke is released. If you can't take in any more, remove your mouth from the bottle.

Step 11. Exhale

Remove smoke slowly from your lungs by exhaling. If smoke remains in the plastic bottle, either take another hit or press down on the bottle to eliminate it. To use your gravity bong again, put the aluminum foil back on, add more cannabis, and repeat the process.

Safety Tips When Using A Gravity Bong

Safety and health precautions are a top priority when using a do-it-yourself gravity bong. Here are some key factors to consider.

  • Materials: Use safe materials when building a gravity bong. Understand the health concerns associated with using materials such as plastic or aluminum, as they can release harmful substances when heated. Opt for heat-resistant options like glass, stainless steel, or food-grade silicone.
  • Water Quality: Always use clean water with a gravity bong. Dirty or contaminated water can introduce harmful particles or bacteria into the smoke, which can then be inhaled into your lungs.
  • Inhalation Safety: Avoid inhaling too forcefully to prevent water from splashing into the smoking chamber, which could lead to accidental water consumption or aspiration.
  • Fire Safety: Use caution when lighting smoking material with an open flame. Ensure there is proper ventilation and no flammable materials nearby. Keep a fire extinguisher or other fire suppression method nearby for emergencies.
  • Hygiene: Keep your gravity bong spotless and bacteria-free for a safe smoking experience. Regularly sanitise and disinfect all its components to guarantee cleanliness and hygiene with each use.
  • Inhalation Risks: Gravity bongs create potent smoke with high concentration. Users must be aware that this method may expose them to more toxins and irritants than traditional smoking techniques. It's important to use the gravity bong moderately and consider its impact on respiratory health.
  • Sharing Considerations: Use separate mouthpieces or sanitise the mouthpiece after each use to prevent the spread of germs and infections when sharing the gravity bong with others. Hygiene is essential in minimising illness transmission.

Making your own DIY gravity bong poses health risks due to the materials used. Several DIY gravity bongs use unsafe materials like plastic bottles, aluminum foil, or others that release harmful chemicals when heated. Inhaling these chemicals can cause respiratory problems and other health complications. Additionally, DIY construction lacks quality control, leading to weak structures or leaks, increasing the likelihood of burns or other injuries.

For a safe smoking experience, it's best to buy gravity bongs from trusted sources like Glass Bongs Australia. Their top-notch products are designed with high-quality materials, guaranteeing a secure and reliable smoking experience that avoids the health risks associated with homemade alternatives.
