How to Cut a piece of glass under water
This video shows how a piece of glass can be cut using a pair of scissors into the shape that you want. First, use a permanent marker to draw the outline of the shape you want on the glass. Next, submerge the part of the glass that you want to cut into a basin of water. Using a pair of scissors, start cutting the general outline of the shape on the glass. After you are done with the general outline, you can then trim the glass with it still submerged in the basin of water. Remember to be careful because glass can cut you.
