Yesterday's Design Challenge asked us to make a machine that fit these two simple requirements:
- it needed to complete a task
-it needed to use a motor (which was provided for us).
In the beginning, the team I was a part of tried to build a car. When that proved to be too ambitious, we made a simple "elevator." We attached the motor to the edge of the table, then we taped a nail to the end of the motor. We clipped a binder clip to this nail. Then we looped a string through a cup and hung it onto the binder clip. Once we completed the circuit and allowed the motor to run, it would spin. The string that was around the cup would then twirl itself around the motor (like spaghetti on a fork). This brought the cup up from the floor to the table. But we still felt like it was missing something, so we added a penguin and voilà! The penguin elevator was created.
