Cut and fold a tiny rotor, then test how blade size changes the fall.
Age 7+10 minAir Experiment
Try it first. Read the explanation afterward.
WHAT'S HAPPENING?
There is a reason.
Air resistance and rotation slow the fall. Changing the blades changes how the paper interacts with air.
These activities are designed to stay simple, safe and easy to repeat.
