Reversing Mechanical Quartz Clock Direction - Playing Pranks on Friends

A very simple way to reverse a quartz mechanical clocks by flipping the laminated metal electromagnet core. The core is asymmetrically shaped which determines the rotation direction.

Here is a link to Make where they've done this also. http://backwardstime-moddy.blogspot.com/

Could be used for counterclockwise motion, pranks or novel custom clocks.

Awesome. I'm so going to do this to the clocks in my house. I might even create a new clock face with the numbers reverse too just to freak anyone out who sees it.
