While watching the Olympic Winter Games, you might have wondered why skis, which are featured in several events, are so long. The skis used at the Olympics are of top-notch quality. Researchers tinker with every detail, from the materials they are made of to the shape they are cut in. The equipment is tested carefully, as details like these can give an athlete the leading edge on the slope. But why would you put planks under your shoes in the first place? Do this activity to find out! Read more
