The bucket bong is another full-hit wonder. It's simple to prepare.
Get your big bottle and cut away the bottom. Put the bottle in the bucket
so it touches the bottom. Then fill the bucket with water. The water
level should not rise above the bottle neck. Place the 'mix cone' onto
the mouth piece of the bottle and apply flame to the 'mix' continuously
as you raise the bottle away from the water. This crates suction and
you'll see the smoke being drawn into the bottle-chamber.
Once the bottom of the bottle has just reached the waters surface, quickly
remove the 'mix cone' and place your mouth over the bottle's mouth piece,
then push the bottle down again, while you inhale the smoke getting
pushed up.
