OK, “build” is not the best word. How about “make” an electric motor that will run in excess of 10,000 RPM in 30 seconds?
All you need is one drywall screw, one 1.5 V alkaline cell, six inches of plain copper wire, and one small neodymium disk magnet. You do not need any other tools or supplies.
Instructions (with pictures) Hey, even I could do this!
