Kites are a great way to combine science, playfulness, patience and imagination. So grab a some simple household items and start building!

Safety: Remember to be sunsmart when you’re outdoors flying your kite, and tell an adult if you’re going further than your backyard.

What’s happening?

The science behind flying a kite is actually quite similar to aeroplane flight. They are both affected by the movement of air and the forces of gravity, lift, thrust, and drag.

Kites achieve lift because of the angle they fly into the wind. As air hits the kite it is deflected downwards. If air is being pushed downwards, according to Newton’s third law where every action has an equal and opposite reaction, the kite is pushed upwards. This upwards lift is able to overcome gravity.

A kite cannot produce its own thrust and relies on being held in place while the wind moves past it. In some cases this is helped by running into the wind with the kite. As you hold onto the kite string, this allows the wind to move over the kite and in effect, generate thrust.

Any kite will have friction with the air – known as drag. Drag can be created by giving a kite a tail. Air flows through the kite tail, pulling the bottom of the kite into the wind. This helps the kite continue to point into the wind and continue flying.

Real-life science

Humans have been flying kites for a very long time. The ancient Chinese were great kite builders. Legend has it that lightning was discovered to be electric during a do-it-yourself science experiment by Benjamin Franklin holding a kite in a storm — not one to try at home though.
