    摘要: A boomerang comprises a member having two arms 11, 12 including an angle in an L-shape. At least one arm itself has two portions 13, 14 including an angle, but this angle is in the opposite sense to the angle of the L and preferably larger in magnitude. There may be one or more apertures 35-37 in the region of the junction 17 between the two arms, and when there is a plurality of apertures they may be arranged linearly, decreasing in size towards the leading edge of the region as the boomerang spins.
