Like orangeman said, use a socket. Tinfoil wont work because it isnt that airtight and most of the air wont get sucked into it. Go to All Original Drunk Videos, Shamings, Funny Videos, Weed Videos, and Funny Pics and Forums! and search for how to make a gravity bong.(They call a waterfall bong a gravity bong)
halo Reviewed by halo 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
