Cut Glass Using Water and Scissors!

Did you know you can cut glass under water… with scissors?!  This video from YouTube shows how it is done.  I also googled it a little bit to find out why this works and here is what i found:

According to Scientific American, water causes glass to crack more easily because when a water molecule enters the crack, a reaction occurs in which a silicon-oxygen bond at the crack and an oxygen-hydrogen bond in the water are cleaved, creating two hydroxyl groups attached to silicon. As a result, the length of the crack grows by the size of one bond rupture. The water reaction reduces the energy necessary to break the silicon-oxygen bonds, thus the crack grows faster.

And now for the video:
