Well I made this today cause I was itchin' to make SOMEthing. Its jus made from a crystal light container, the top of a plastic vodka container, airsoft bb's, and some metal tube lol. Of course with some wood glue and duct tape for structure and sealing I still need to get a bowl piece for it but I tried it out earlier with a mini joint on a clip like in the metal tube xD But it works perfectly! There's enough room for some ice to go in it too.
Lol I can only get one or two used out of it before the diffuser falls down into the water though.. Guess wood glue doesnt work.. I need to like melt the vodka bottle tip onto the bottom of the lid.. Think that'd do it?
