Absolutely Mesmerizing, Giant Pendulum Wave Demonstration with Bowling Balls [VIDEO]
Many people have encountered pendulum waves, but usually the pendulum is small enough to sit on a desk. But what if you scale it up?
This large-scale pendulum wave demonstration uses 16 bowling balls that create the most mesmerizing swinging patterns. The bowling balls are hung in specific spots, measured precisely from a wooden frame to ensure they swing in the right way. On the video’s YouTube page, Maria Ikenberry, who uploaded the clip, writes:
The length of time it takes a ball to swing back and forth one time to return to its starting position is dependent on the length of the pendulum, not the mass of the ball. A longer pendulum will take longer to complete one cycle than a shorter pendulum. The lengths of the pendula in this demonstration are all different and were calculated so that in about 2:40, the balls all return to the same position at the same time.
This mechanism was built and the demonstration completed in North Carolina. Because it is outdoors, many factors prevent the bowling balls from exactly lining up at the end.
