The most bongs I ever made in one night is like, two.

We decided to experiment, so we made a pineapple bong (I'd post pics of it but I don't have the hardware). That was okay, but not very smokable. I think there was too much air getting through.

Then I tried to make an apple bong, but that sure didn't work out. I don't know what I was thinking, I guess I smoked too much.
