I made a nice homemade gravity bong hits like a cannon only problem is as im rising it out of the water the bottle itself seems as though it keeps the water suctioned inside it. It still fills up with smoke about a quarter of the way but it wont seem to let the water out. As i rise it its like the water wants to stay in the bottle any ideas?
There's not enough air coming through the top. Get a bigger socket, clear your bowl and don't pack it too tight. Simple physics.
Use a paper clip or something to poke a hole through the middle of the pack post-pack if the problem persists. That's what I always did when I smoked bud/gravs.
