Crystal transistor limiter circuit A gravity bong, also known as a GB, geebie, bucket bong, grav, geeb, yoin, jib, buckie or ghetto bong, is a method of consuming smokable substances such as cannabis. The term describes both a bucket bong and a waterfall bong, since both use air pressure and water to draw smoke. A lung uses similar equipment but instead of water draws the smoke by removing a compacted plastic bag or similar from the chamber.
