Force of a Water Drop
Get a match and make a notch in the middle of it, bend it so as to form an acute angle, and place it over the mouth of a bottle. Now place a dime or other small coin on the match and ask any one to get the coin into the bottle without touching either the bottle or the match.
This is very easy to do. Dip your finger in a glass of water, hold it over the place where the match is notched, and let one or two drops fall on this point. The force of the water will cause the sides of the angle to move apart, and the opening thus become large enough to let the coin fall into the bottle. We enjoy magic shows and are willing to suspend disbelief while we watch them. Magic was not always well received. For many years it was seen as a type of witchcraft and the practitioners were believed to be witches or sorcerers who had magically powers. Those powers made them both dangerous and the objects of witch hunts.
