Materials: Malma Mirror, 3/8″ glass drill, clock work
Description: Carefully drill a hole in the center of the mirror with the glass drill. I use a drill press to do this but it can be done with a regular drill motor. The trick is using a glass drill bit- one made for drilling through glass. Once the hole is made, install a clock work through it. In case you crack the mirror you can replace it with a 4″ tile. If you use a tile you need a masonry bit. You can probably use the glass bit though. The end result is a cool mirror that reflects time.
