A boomerang is like a propeller

When you throw the boomerang: 

• It not only spins propeller motion but also flies through the air.
• The wing at the top of the spin moves in the same direction as the forward motion of the throw, while the bottom wing mo...

Returning boomerangs are the banana-shaped devices that come back to you when you throw them.

The returning boomerangs are made from lightweight pieces of wood, plastic or similar material and generally measure 1 to 2 feet (30 to 60cm) across. When thrown correctly, a returning boomerang f...

Non-returning boomerangs are effective hunting weapons. They are easy to aim and can travel a longer distance at a high rate of speed.

These boomerangs are made from pieces of wood shaped in a curve, but they are usually heavier and longer than the returning boomerang, about 3 feet (1 metre...

There are five variables involved in a boomerang flight:

• The force of gravity
• The force caused by the propeller motion
• The force of your throw
• The force caused by the uneven speed of the wings

A boomerang has at least two wings combined in one unit. It makes a boomerang spin about a central point, stabilising its motion as it flies through the air.

The wings are set at a slight tilt. They have an airfoil design - rounded on one side and flat on the other - which gives a wing lift...

1. Hold the boomerang at the end of the bottom wing, with the V-point pointing toward you, the flat side facing out. The curved edge will be on the left and the top wing's leading edge facing away from you.
2. Aim the boomerang at a point about 45 to 50 degrees to one side from the wind di...
