What Is a Pinwheel?
A pinwheel is a simple toy made of blades attached at an angle to a central hub, which spins when blown by the wind or when you run with it. Known for its vibrant colors and joyful motion, the pinwheel has delighted children (and adults!) for generations.
How Does It Work?
When wind hits the angled blades of a pinwheel, it creates lift and drag forces that cause rotation. This basic principle demonstrates early concepts of aerodynamics and wind energy in a playful way!
