Abstract
A modifiable boomerang comprises of a pair of wing blades which have a curved top surface and a flat bottom surface. The wings are connected together by a pivot bolt to form a boomerang whose angle can be adjusted to change the aerodynamics of the flying boomerang. A thrower can change the angle of a boomerang to change its flying pattern.
