Bear with me here.
There is a basic concept in physics that, if you wish to fling a non-spherical object a long distance, the way to do this accurately is to impart spin on it. This stabilizes the object in flight and prevents tumbling that will make it veer off course.
The usual way this concept is taught in the U.S. is by reference to American football, where an oblong ball can be accurately thrown a long distance with a "spiral" pass that stabilizes its course. If one later learns about firearms and artillery, then rifling proves the same point. But I doubt either of these would be appropriate references for primary education in much of the world. Most popular sports in Europe have spherical ball (and rugby isn't popular everywhere.) Rifling seems politically sensitive, perhaps excepting Switzerland. I think I had a toy gyroscope as a kid but even that feels like a pretty narrow niche.
So, how did you learn this concept? How would you explain it to, say, a ten-year-old child?
