1. Clip the binder clip to the end of a half meter stick. 2. Lay the stick on your desk so that only the clip extends over the edge.
Use a piece of duct tape close to the clip so the stick doesn't slide from side to side.
Put a dictionary or other heavy book on the other end of the stick to hold it down.
Use the pulley, rope, and load to find out how you can use a pulley to lift a load.
