How to: Make a Simple Electric Motor

"Oskay" shows us how to make a simple electric motor in just 30-seconds using "one drywall screw, one 1.5 V alkaline cell, six inches of plain copper wire, one small neodymium disk magnet, and no other tools or supplies." Full instructions here. Video demonstration after the jump.
This type of motor attracts an electromagnet towards a permanent magnet. When the two are close enough,the polarity of the current through the electromagnet is reversed, so that it now repels the permanent magnet, and thus keeps turning
