How do I take a "Bong" Rip and filter the smoke out completely?

So I'm a pure rookie to this here ol' Website. I am really investigating how to develope a real smokeless bong(Like Harold&Kumar2). Definetly not for mass marketing/production ....yet!. I'm open for suggestions that sound practical and reasonable. Help me out if you got any ideas and/or websites of stuff that already do it.. Thanx
