A Few Joints Where Rivets are Used to Hold the Parts Solidly Together
A Whistle
Cut a circular piece of tin any convenient size, preferably 3 in. in diameter, and bend it across the diameter so that it will be in a narrow U-shape. Then drill or punch a hole through both parts as shown. Place it in the mouth with the open edges out, being sure to press the lips on the metal tightly on both upper and lower pieces outside of the holes and to rest the tongue against the edge of the tin, even with the holes, and blow.
The result of the first attempt may not be a sound, but with a little practice any familiar tune may be whistled.—Contributed by Chas. C. Bradley, W. Toledo, O.
Card-and-Coin Trick
If a card is balanced on the finger and a coin placed on the card directly over the finger, one would not think that the card could be flipped out leaving the coin on the finger end. This is easily accomplished, if care is taken to snap the card sharply and squarely.—Contributed by R. Neland, Minneapolis, Minn.
