How to Make a Gravity Bong

Have fun with this one!

A few materials you are going to need are: two-liter plastic soda bottle or water bottle, a trash can, 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.

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.
