A golf ball has dimples to improve its aerodynamics and flight performance. The dimples create a thin turbulent boundary layer of air around the ball, which reduces drag and allows the ball to travel farther. Without the dimples, the ball's surface would create a larger, thicker layer of turbulent air, increasing drag and reducing distance. Therefore, the dimples help the ball achieve a more efficient and stable flight. **

Some water bottles have indentations at the bottom to provide stability and prevent them from easily tipping over. The indentations create a wider base, which helps to distribute the weight of the bottle and its contents more evenly, making it less likely to topple. This design feature is especially useful for larger or taller water bottles that may be more prone to tipping when placed on uneven surfaces. Additionally, the indentations can also make it easier to grip and hold the bottle securely. **
