gb’s

gravity bongs; using a water bottle that has a hole at the bottom with a piece on top to hold weed on the lid. you essentially burn a hole at the bottom of the bottle, cover it with your finger & fill ‘er up with water, place the piece that holds the weed on top & light it while uncovering the bottom hole so that the water pouring out pulls the smoke. once the bottle is filled, take the piece off & inhale the smoke.
