Alright so I saw a couple posts on here with similar how tos but I thought I'd throw one up. Things you will need - one mason jar whatever size you want - two to three empty white bic pen tubes - one trumpet mouthpiece (can be found at music store for 10$) -hot glue gun or other sealing method ex. Duct tape. Because I didn't take pictures before I assembled mine I had to image shop for pictures so in the picture that gives the two holes in the lid example please ignore everything eles in the image. Assembly - use a sharp object to poke two holes in the lid of the mason jar making sure to make one of the holes slightly smaller then the other - next take the little plug in the back and the tip off the pen and pull out the ink cartridge and shove the pen tube through the slightly smaller hole push the pen tube 25% into the jar and seal with sealer - empty the insides out of your second and maybe third pen depending on how large your jar is just make sure the end of the tube is about an inch above the bottom of the jar -tape the pen tubes together and to the trumpet mouthpiece - push the trumpet mouthpiece attached to the pen tube downstem through the lid until only the bowl is outside of the jar - seal - make one last very small hole in the lid for a carb - pack some bud enjoy!
