Episode 81: Bow & Arrow

There are two types of Tsou arrowheads: bamboo and iron. The bamboo arrowhead is fitted with two pieces of feathers for the fins. The iron arrowhead has three. Adding feathers stabilizes the arrow when it flies. In this episode, the kids throw long shaped balloons to understand the function of stabilizing fins. They even use a small wind-tunnel to observe the difference between arrows with fins and arrows without them.
