corner to corner, both ways. Then open the paper, and with a pair of scissors cut along the diagonal creases, from the corners to within ½ inch of the center (Fig. 2). Next, fold corners A, B, C, and D over to the center, as shown in Fig. 3, run a pin through the corners and through the center of the sheet of paper, drive the point of this pin into the end of the stick handle, and the pinwheel will be completed.
Fig. 2.—Diagram for Paper Pinwheel.
The Pinion-Wheel Windmill in Fig. 4 may be made of cardboard or tin. A circular piece 10 or 12 inches in diameter is required. After marking out the outer edge with a compass, describe an inner circle about 1 inch inside of it; then draw two lines through the center at right angles to each other, and another pair at an angle of 45 degrees to these. These lines are shown D by the heavy radial lines in Fig. 5.
