A reel may be glued on the top of the arms for turning the airships; cotton may be wound round this, and when pulled causes the cars to revolve. Into the hole of the top reel may be inserted a stick bearing a flag.
Paint the cars according to taste.
When the top reel is set spinning the cars fly round and outward in a delightful manner, gradually returning to a vertical position as the speed lessens.
Gondolas. For the cars gondolas may be substituted, as in Fig. 208. These gondolas form simple and effective paper toys, even if not attached to revolving arms.
Draw on stout paper or cardboard and cut out the two sides, A A, as in Fig. 208. The total length of the boat should be 9 inches.
Next draw a line on a piece of paper, a´ b´ in Fig. 209, the same length as a b in Fig. 208. Divide the line into three parts at c´ and d´. a´ c´ represents the length a c in Fig. 208; c´ d´ (not shown to scale), the length of the cabin c d. If the full length of the gondola is 9 inches, the length a b will be about 8½ inches, and the length a c should be 3 inches; this makes the length of the cabin, c d, about 1¾ inches. Draw two lines at c´ and d´ at right angles to a´ b´. Make e f and g h (Fig. 209) equal to the widest part of the gondola. (If the length of 9 inches has been decided on, the width of the gondola should be 1¼ inches.) Complete triangles a´ f e and g b´ h as in Fig. 209; draw flanges as in diagram and cut out. Two other triangles exactly the same size with flanges will be required.
