A Safe Bet
Lay a dime, or a dollar if you feel so inclined, upon the palm of your hand, and promise to give it to whoever can brush it off with an ordinary clothes brush, as shown in [Fig. 11]. The only condition you need make is that they shall brush towards the tips of the fingers and not to one side.
You need have no fear of the result, and can feel quite assured that your money is as safe as if it were in your own pocket. Whatever the explanation may be, the fact remains that no amount of brushing will move the coin the hundredth part of an inch on your open palm.
