Does it make any difference if you put alcohol instead of water in your bong? Like, does it make you any higher? And does anybody else do what I do--I put in tiny ice cubes (you can buy tiny ice cube trays from Kmart or Wallmart) into the water, making the water really cold. It really helps cool the smoke, and you get a cold sensation when you first inhale the smoke. It's pretty awesome. I guess this is similar to gravity bongs, or whatever you call it with the ice, but I never figured out how to make those things.
