The paper was folded into a wheel, the pin inserted at the heart of it and the entire structure fixed to the broomstick.</p> <p>As our pinwheel took shape we ran out braving the sun and the hot wind. The pinwheel caught the wind and rotated. Seeing it, our hearts pin-wheeled as well.</p> <p><strong>Energy from wind</strong><br> A few days later we happened to see the photograph of a windmill in a magazine. &ldquo;Don&rsquo;t these windmills look exactly like the pinwheels we made?&rdquo; my cousin shouted. And what did we find? That they are actually similar! Like the pinwheel, the windmill also uses the wind&rsquo;s energy to turn the blades on a large wheel. This movement of the blades is used to pump water, generate electricity or pound grain.</p>
