Here is a diagram for you to consult if you don't completely understand the directions.
Step 4: Assembly (Continued)
Cut a six inch section of fishing wire and tape one end to the base of the plastic container (try to find a container like mine, it works best). Tape the other end to the ceiling about four inches away from the scotch tape spool. Tape the end of your spool of fishing wire opposite your horizontal cylinder and measure out how much wire you need to pass through all the pieces and get to your container. Cut the wire and string it through your pieces and tape it to the plastic container. Pull the slack out of your wire to where the container is about tong the tape spool.
Note: I know this is hard to follow but bear with me and consult the pictures and diagram.
