Making a bong...??

[Cacophony]

If I take a 4x4 piece of a coke can or whatever, I have to roll it into a cone, and I ahve to leave some of it open in the bottom right? won't the weed fall in?

I've never used a bong before so explanation would be good.

There's a demonstration in the video section of http://www.everyonedoesit.com
