ur usin the wrong materials i would suggest a trumpet mouthpiece or socket for the bowl then some how poke the bowl thru the bottle cap that way the natural srew cap can make an nice tight seal, afterwards burn a small hole about the size of a pencil hole into the bottom of the bottle, for a screen you should use a sink screen, fill the bottle with water, light then get high
JaMakin07 Reviewed by JaMakin07 on . Waterfall Bong help/questions I recently found out the general concept of a waterfall bong and rushed to make one. I used a regular water bottle, poked a pencil sized hole near bottom, and made a tinfoil bowl for the top of the bottle. For some reason it seems like alot of the smoke it just floating up and only a little is going into the bottle. And also how big should the hole be? with the one I made the water drained out in like 10-seconds. Thanks for all the help! :jointsmile: Rating: 5
