napolitana869 Reviewed by napolitana869 on . 2 liter gravity bong take a two liter and poke a hole at the bottom, put tinfoil and weed in the cap part, after youve filled the 2 liter with water and have you finger over the hole. Light the bowl and remoe your finger and the bottle fills up. is that easier than a regular gravity bong? Rating: 5
