A gravity bong hit. This is a specific type of gravity bong hit originated in Akron, Ohio. The bong hit is taken from a two-liter soda bottle, which has had its bottom removed. The cap of the bottle has a bowl head that is placed into the top. This contraption is then inserted in to a source of water that covers at least half the bottle. Insert smoke. Pull the bottle from the water while the cap is attached. Hold a lighter to the bowl while gravity forces the smoke magically into the bottle. Remove the cap and let Sir Isac Newton do the rest.
