<strong>Boomerang</strong> basically acts on The Bernoulli’s principle How does a boomerang return to the thrower? When you throw a boomerang you not only impart great speed but also a certain amount of spin. The spin at the top is more than at the bottom. Because the design enables the top of the wing to move forward and at the same time spin forward as well, for the same reason, the bottom portion spins not very fast but it surges forward and effects the lift.

Topside spins forward – backside spins backward. Result? When the boomerang loses momentum the spin creates a gyroscopic precession, which propels it to turn to the left enabling it to fly back in a circle to whoever threw it. Sunday, May 30, 2010 11
