A gravity bong is a simple but effective way to enjoy your favorite herb or tobacco. It uses two empty plastic bottles and some water to create a vacuum that pulls the smoke into your lungs. It’s also very easy to make with items you probably have at home. Here’s how to make a gravity bong in 10 minutes or less.
What You’ll Need
- An empty plastic bottle (any size, but smaller bottles are easier to use)
- An empty plastic container or bucket (slightly larger than the bottle)
- A bottle cap
- Aluminum foil
- A toothpick or a pin
- Some herb or tobacco
- A lighter or matches
Step 1: Make the Bowl
The bowl is where you’ll put your herb or tobacco. To make it, you’ll need to punch a hole in the center of the bottle cap. You can use a knife, scissors, a drill, or any sharp tool. Make the hole about the size of your pinky finger.
Next, take a piece of aluminum foil and wrap it around your finger to form a bowl shape. Place the foil inside the bottle cap and press it down. Make sure the foil covers the hole in the cap. Then, poke some small holes in the foil with a toothpick or a pin. These holes will allow the smoke to pass through.
Finally, fill the foil bowl with your herb or tobacco. Don’t pack it too tight or too loose. You’re ready to move on to the next step.
Step 2: Make the Bong
The bong is where you’ll create the vacuum that will suck the smoke into your lungs. To make it, you’ll need to cut off the bottom of the plastic bottle. Use a knife or scissors to carefully cut around the bottle, about 1-2 inches from the bottom. Discard the bottom part and keep the top part with the neck and mouthpiece.
Next, fill the plastic container or bucket with water. You can use cold or warm water, but not too hot or too cold. Fill it almost to the top, leaving about 1-2 inches of space.
Then, submerge the bottle in the water. The open bottom of the bottle should be at the bottom of the container, and the neck and mouthpiece should be above the water. If the water covers the mouthpiece, you’re pushing the bottle too far down.
Step 3: Use the Bong
Now comes the fun part. To use your gravity bong, you’ll need to screw the bottle cap with the foil bowl back on the bottle. Make sure it’s tight and secure.
Then, light your herb or tobacco with a lighter or matches. As you do this, slowly lift the bottle up from the water. You’ll see smoke filling up inside the bottle. Don’t lift it too high or it will come out of the water and lose suction.
When the bottle is almost full of smoke, unscrew the bottle cap and put your mouth over the mouthpiece. Quickly push the bottle down into the water as you inhale. This will force all the smoke into your lungs in one go.
Hold your breath for a few seconds, then exhale and enjoy. Repeat as desired.
