We first observe the behavior of a tennis ball when thrown from different heights, such as the abdomen, shoulder, and beyond the head. We notice that the tennis ball does not return to its original height after being thrown. Next, we repeat the experiment using a basketball, which is larger and heavier than the tennis ball. We throw the basketball from various heights and observe that it comes closer to its original height after being thrown, reaching 80-90% of its height. The basketball bounces higher than the tennis ball. We then ask the question, if it\'s possible to make a tennis ball bounce to three times its height with a normal throw.
