all you need to do to make a bong is have a place to bowl (place to put the weed) since it's a bong you'll need somthing that has a chamber (big empty space that fills up with smoke) and depending on the set up might need a carb (basicly a must on almost any bong unless it's like a GB, or lung or steam roller) or instead of a carb you can make a slide....be creative learn from you mistakes and if you ain't got hotglue electiral tape is one of the best tapes to use for bongs since it is easily strechable and it's airtight if done right...also keep the bong as simple as possible....the more complicated the more problems you're likely to have.
