Cross-Stick Boomerang

Fo make a cross-stick boomerang you will need two pieces of clear white pine V thick x IV*" wide x 18" long. Round off the ends, place each stick on the edge of a knife blade, and mark the balance points. At a point 1" from each side of the balance point, shape the upper surface of each stick into a roughly convex form as shown in the cross section. Leave the bottom side flat.

Make a mark on the flat side 6" in from each end and then hold the stick over a candle flame so that the flame touches the flat undersurface at the 6" mark. When it is heated, take the stick in both hands and bend one end slightly upward at the 6" mark, and hold it in this position for a few seconds. The end of the stick should remain permanently bent in an upward deflection of about K". Repeat the process at the other end. and then bend the second stick in the same manner. All that remains is to glue and clamp the sticks together, one on top of the other at their balance points.

Throw the boomerang by holding it near the tip of one wing in a vertical position, with the convex side facing you. Throw the boomerang
