Why boomerangs fly
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. The wing has lift when the air particles move quicker over the top of the wing than the bottom, which creates a difference in air pressure, causing lift.

Downwash (downward moving draft)
The second aspect of making lift:
- According to Isaac Newton's third law of motion, if air gives an upward force to a plane, the plane must provide an equal and opposite downward force to the air. That means that the plane generates lift by using its wings to push ai...

- Build a basic paper plane that flies in a straight line.
- Cut or rip the back of the wings to make some ailerons.
- Tilt them up and down and see what effect they have in different positions.

Airplanes: Explaining pressure differences
Most aeroplane wings are curved on the upper surface and flatter on the lower surface, making a sectional shape, named an airfoil.
- As a curved airfoil wing flies through the sky, it deflects the air and changes the air pressure above and below it.
