My friend has one of those. He made a hooka with it. He put in in the middle of a 2 liter bottle filled up 1/2 way with water and taped it to the cap part air tight. Then he put tinfoil in and made it into a bowl (poked holes and such in the tin foil). He then made 1 hole for a carb, then 2 holes for the hooka hoses. He put tape over the carb with a little piece of paper at the end so he can lift it up. He also uses these plastic hoses he found as the hooka hoses. It hits INSANE. I'm ripped off 1 bowl.
