My (Unsuccessful) Motor

Soooo, today in class we had an assignment to complete and test a motor we built with garbage lying around our house. At the end, the motor was supposed to turn three complete rotations for the project to be deemed as a "pass". After a few attempts to complete the motor, it still ultimately failed to spin. The reason for the failure is still uncertain but I for one, am not content that my motor did not function :(. During the test run, only one spark lit up and nothing happened from then on. I guess we'll have to figure it out tomorrow...

Here's a picture of me holding my unsuccessful motor...
