A technique use to smoke weed. First the user takes a bubbler and fills it with water. Then a sweet J is rolled and placed inside the bowl sticking upright like a lighthouse. The user then places even more weed around the J to fill the bowl creating the rocks. The J is smoked and by that time the user cant use a lighter, but one is not needed because the J lights the bowl by itself.
That lighthouse we smoked last night was AMAZING!!!
