The gravity bong (or bucket bong) is a very efficient system for drawing tobacco or other fumes into the lungs. It may seem complicated at first, but it's actually very easy to do. These steps will show you two slightly different ways to make it - both need a few basic materials.
Steps
Method 1 of 2: Waterfall (No Bucket Needed)
Step 1. Get a plastic bottle
A two-liter soft drink is ideal. Pour all your friends a glass, they'll thank you later, when they have a plush mouth - and now you need the empty bottle.
The new design of the coke bottles makes it more difficult to work with some of the caps. If you don't use a Coca-Cola product, try finding other caps
Step 2. Make a hole in the bottle
You can use a drill, or just keep the lighter lit on the plastic (on the side, near the bottom). When the plastic is soft, prick it with scissors to make a hole in it. Enlarge the hole by turning the scissors 360 degrees.

Make the hole large enough so that you can cover it with your thumb. If it is too small there will not be enough draft to make a shot; if it's too big, or even almost too big to cover with just your thumb, take another bottle.
Alternatively, you can use a glass bottle. In this case you will have to use a drill with a tip for the glass, but the idea is the same
Step 3. Make a hole in the bottle cap
Use the lighter to soften the plastic if necessary. Once pierced from side to side, twist the scissors to make the hole round.
A folding knife is ideal because, in general, when the whole blade has passed and stops against the handle, the cut it leaves is the perfect diameter for what you need. Once the cap is pierced, spin the knife slowly to create a circle. In any case, scissors or a drill will give the same result
Step 4. Make the brazier
There are a couple of ways to do this: with foil or with a can.
-
Foil Method:
take a piece of aluminum foil and put it on the bottle cap.
- Press it down with your finger so that it forms a indentation in the hole you just made.
- Wrap the foil around the edges of the cork so that it is stable.
- Finally, use a pin or needle to make small holes in the part of the foil that goes into the hole. Make sure they are small enough not to drop anything inside.
-
Aluminum Can Method:
carefully cut out a rectangular piece from a soda can. Better if empty.
- Fold the rectangular piece into a funnel shape. The top should be wide enough to put the tobacco in, the bottom small enough not to drop anything into it.
- Insert the funnel into the hole in the cap. The cap should divide the funnel in half, the top of the bowl stays out but the bottom goes into the bottle when you put the cap back on.
- Use hot glue or super adhesive to glue the funnel to the cap and make sure the hole is well sealed.
Step 5. Cover the hole in the bottom with your thumb
Make sure it is tightly capped, then fill the bottle with water
- Fill the bowl with tobacco and screw the cap back on.
- Light the tobacco in the bowl and let your thumb go out of the hole in the bottom. As the water comes out, the vacuum will draw the air through the tobacco, into the bottle, which will fill with smoke.
- When all the water has gone out, remove the cap and vacuum.
- If you have a funnel and a container, you can recycle the water (you can make a funnel out of a can as described above, just bigger). This makes the method portable, and usable for good or bad wherever you usually go to smoke.
Method 2 of 2: The Bucket Bong
Make a Plastic Bag Holder Step 3 Step 1. Cut the bottom of a plastic container
Use at least a 2-liter bottle - but a 3-liter is even better.
Empty it. Make a note of the contours of the bottle before cutting it. There is usually a ring above the five-fingered base. It's a great guideline
Step 2. Make a hole in the lid
With a 15 mm tip make a hole in the center of the cap; if you don't have a drill, heat the plastic with a lighter until it softens, then pierce it with an iron rod to get an airtight seal.
Step 3. Make a brazier
Use a socket wrench attachment, a bowl from another water pipe, or a funnel as described in the previous method.
Step 4. Get a bucket
You will need one large enough to submerge your container completely. 5 liter containers are very good.
- Fill it with water. Put the container in the water without a cap. The top of the container should be a few inches above the surface of the water.
- Fill the bowl with your smoking substance and screw the cap on. Make sure you put the container in the water before screwing the cap on, or it will blow your herbs out of the container.
Step 5. Light the herbs
As you turn on, slowly take out the water bottle. The bottle will fill with smoke.
When the container is almost full and before the bottom comes out of the water, get ready: exhale
Step 6. Take a nice shot
Remove the cap and put your mouth on the top of the container and, without inhaling, push the bottle down until it touches the bottom of the bucket. This will push the smoke into your mouth without even inhaling. When the bottle reaches the bottom, vacuum the rest and remove your mouth before the water rises to the edge.
If you inhale while pushing the bottle down, you may not be able to empty it completely
Advice
- If you push the container down as you inhale, the smoke will be pushed into you and you will inhale much more.
- This design can easily be changed to filter the water yourself. Find some tube of the right size or fit it to the bottom of the bowl and let it go down into the water. You will have to try and adjust the length of the tube before it works well. The tube should end approximately 3 to 8 centimeters above where the bottle is cut. This will also - but not much - change the technique to use when pulling the bottle up, since the sucking will begin once it is raised only a few inches, and the smoke will begin to fill the bottle. This smoke should be softer and easier to taste.
- Ice can be added to the water for a cooling effect.
- A good organization could include the use of a 2-liter bottle, and a 5-liter container. The bottle fits perfectly in the container.
- You can also make a vacuum hole in the bottle, so that you can suck up any residual smoke after the bottle has been pushed all the way.
Warnings
- The foil and aluminum can method are extremely harmful to the lungs. For a healthier option, use a glass or metal bowl.
- Only those over 18 should smoke.
