There happened to be a very interesting case a few days ago involving the accidental killing of a young man by his own boomerang. I found the boomerang itself to be quite remarkable and examined the science of it's inner workings. The boomerang works on a combination of different physical principles, such as lift and how it generates torque, which allows the boomerang to curve back around to its thrower. A boomerang spins as it flies, which makes it different than an airplane's wings because the aerodynamic lift is not the same across all parts of the boomerang simultaneously. This unfortunate young man had not been paying very good attention to his boomerang and as he turned his head, his own recreational tool came back and hit him in the side of the head, causing blunt trauma to his head, bruising the inside and causing pressure from the blood to kill him.
