Cutting Glass with Scissors. "Magical Experiments or Science in Play" by Arthur Good. Philadelphia: David McKay, (1894).
With an ordinary pair of scissors you can cut a sheet of glass -- a window pane, for instance -- as easily as you can cut a sheet of pasteboard.
The secret of this experiment consists in plunging your hands, with the glass and scissors, into a tub of water, and there performing the operation. In this way the glass cuts in straight or in curved lines, without break or crack; for the water deadens the vibrations of scissors and sheet of glass. If the operator allows the smallest part of the scissors to appear above the water, the vibrations will be sufficient to prevent the success of the experiment.
