How to Make a Gravity Bong: Step-by-Step Guide

Greetings, dear reader! Have you ever heard of a gravity bong? Well, if you haven’t, let us explain what it is. A gravity bong is a smoking device that is quite popular among cannabis enthusiasts. It works by using gravity to pull smoke into a container, providing a stronger and more potent hit compared to other smoking methods. If you’re interested in learning how to make a gravity bong, then you’ve come to the right place. In this article, we’ll be sharing with you the 12 steps needed to make one, as well as some helpful explanations and tips. So, let’s get started!

Steps how to make gravity bong

Step 1: Gather Your Materials

The first step in making a gravity bong is to gather all the necessary materials. You will need a plastic bottle (2-liter works best), a metal bowl (like the ones used in bongs), a lighter, a knife or scissors, and some water.

Step 2: Cut the Bottle

The second step is to cut the plastic bottle in half. You can do this by using a knife or scissors to make a clean cut along the mid-point of the bottle. Make sure to remove any plastic shards or pieces after cutting.

Step 3: Punch a Hole

Next, punch a hole in the bottle cap, making sure it’s large enough to place the metal bowl on top. You can use a lighter or sharp object to make the hole.

Step 4: Create a Bowl

Using the metal bowl, craft a bowl that fits snugly over the hole you just made in the bottle cap.

Step 5: Fill with Water

Fill up the bottom half of the bottle with water until it is about an inch above the hole in the cap.

Step 6: Pack the Bowl with Weed

Pack the bowl with your preferred cannabis strain, making sure it’s not too tightly packed.

Step 7: Light the Bowl

Light the cannabis in the bowl while slowly lifting up the bottle from the bottom.

Step 8: Let it Fill with Smoke

As the water drains out of the bottle, it creates a vacuum that fills the chamber with smoke. Be sure to keep lighting the bowl until the bottle is filled with smoke, or until you reach your desired amount.

Step 9: Remove the Bowl

Once you’ve filled the bottle with enough smoke, remove the bowl from the cap.

Step 10: Inhale the Smoke

Place your mouth over the bottle opening and slowly lift it up, letting the smoke rush into your lungs. Be careful not to inhale the water.

Step 11: Enjoy the High

Hold your breath for a few seconds before breathing out slowly. Depending on your tolerance, the effects of the gravity bong hit should last anywhere from 30 minutes to an hour.

Step 12: Clean Up

Clean the bottle and bowl with dish soap and warm water to remove any residue.

Explanation how to make gravity bong

Now that you know the steps to making a gravity bong, let’s dive into the explanation behind them. The reason why this device is called a “gravity bong” is because it uses gravity to create a vacuum that sucks smoke into the chamber. When you light the cannabis in the bowl, it creates smoke that fills the chamber as the water drains out of the bottle. Once the bottle is filled with smoke, you inhale it by lifting the bottle upwards. This method of smoking is said to provide a stronger hit because the smoke is more concentrated than in other methods.

Tips and Tricks how to make gravity bong

Now that you know how to make a gravity bong, here are some tips and tricks to make it an even better experience:

1. Use a slow-burning cannabis strain

To maximize the use of your gravity bong, it’s best to use a slow-burning cannabis strain. This will ensure that you get the most out of your hit.

2. Don’t overdo it

Gravity bongs are known to provide some of the strongest hits, so it’s important to not overdo it. Take it slow, and enjoy the high.

3. Make sure the bowl fits correctly

The size of the bowl should fit perfectly onto the bottle cap. If it’s too big or too small, it won’t work properly.

4. Clean up after each use

Be sure to clean the bottle and bowl after each use to prevent any buildup of mold or bacteria.

5. Use cold water

Using cold water in your gravity bong can help reduce harshness on your throat.

6. Experiment with different flavors

Adding different flavors to your water, such as mint or citrus, can enhance the taste of your hit.

7. Practice safety

Always use caution when dealing with fire and hot materials. Ensure that you’re using your gravity bong in a safe environment.

8. Share the experience

Gravity bongs are a great way to have a fun smoking experience with friends. Don’t be afraid to share the experience with others.

9. Try a diffuser

Using a diffuser can help to make your gravity bong hits smoother.

10. Enjoy the ride

Lastly, remember to enjoy the ride. Gravity bongs can provide an intense high, so sit back, relax, and enjoy the experience.

That’s it! You now know how to make a gravity bong. With these steps, explanations, and tips, you’re well on your way to becoming a gravity bong pro. Just remember to take it slow, be safe, and enjoy the high. Happy smoking!
