Innovative activity: Makedo Windball

Instructions Makedo Windball is a simple, yet unique geometry project. Basically, all you do is assemble simple cardboard and turn them into a kind of art form. The main idea behind the project is actually quite abstract; it shows that there is no truly perfect sphere in this world. In addition, you can prove that spheres are made out of squares, hexagons, or triangles. To begin, realize the following statement is true: There is no perfect spherical or circular object in our universe, and there will never be. The planets, raindrops, marbles, coins; none of these are perfectly rounded. You may think that gravity is holding us back from a perfect sphere, affecting the shape of the earth or of a raindrop, but even if there is no gravity, we still wouldn’t have a perfect sphere. This can be proven by you zooming in far enough- you will start seeing the edges of molecules. On Youtube, the user Veritasium explains this in a beautiful way. A Makedo windball is the best way to grasp this idea. You are taking something that exists in square form and making it into a sphere. In the beginning, you need 32 12-inches squares. When you connect all of them, you will see some gaps in the shape of pentagons and triangles. To make that gap smaller, you will need smaller squares to fill it in. Every time you make your squares smaller, you will get closer to the perfect sphere. But keep this in mind; you can make it as round as you can, but it will still have miniscule holes , and it will not truly be a perfect sphere.
