A few materials you are going to need are: A Trash Can (or large bucket) ,two-liter plastic soda bottle or water bottle, water, scissors and a bowl head froma metal pipe.
- Using scissors, cut off the bottom of the bottle.
- Poke a hole in the lid or cap so that the bowl head can be screwed in. Make sure that the bowl fits tightly. Chewing gum is a good way to seal the holes around the bowl. Bowls can be made with a variety of creative things.
- Thread the bowl into the cap and place the cap back on the bottle.
- Put the bottle in a bucket (tub, trash can, ect.) of water. Hold a lighter to the bowl and pull up on the bottle to draw the smoke in.
- Remove your cap and place your lips over the opening. Push the bottle back into the water while inhaling.
Tips on how to hit the bong effectively: Pull the smoke in slow at first and the back end of the hit is when you are going to pull in fast and deep.
