Ok well for all you out there that dont want to purchase bongs, pipes etc. I have made a good amount of tools. If you dont have access to proper pipe screens at a head shop and your desperate. At walmart they have water aerators in the plumbing section and if you open one up it has 2 good metal screens in it. Also as a stem i will usually use a pen shaft then attatch a nut to the top with the earbud metal mesh as the screen. But if you have a 2 piece highlighter and you take it apart you can make a slider too. Then just make a hole in a bottle and smoke up. Another thing u can use for screens are old earphone buds (the metal mesh part). If you dont have a pipe and u just want something you can smoke and ditch. You can get stainless steel nuts at any department store for like 10 cents each. Take a empty earbud and squeeze it into the shaft of the pen. Then use duct tape or glue and attatch the nut and make it airtight. If you want to add a carb, just make a hole on the pen shaft. Got any other good ideas for "makeshift" tools please share...
