Finding the Sweet Spot

In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response. These vibrations travel in waves up and down the length of the object. At one point, called "the node," the waves always cancel each other out. The "sweet spot" is actually a node!
