Attention all aspiring mechanical enthusiasts! Our newly launched "Unique Gear Wall" will transport you to a world of ingenious mechanics, allowing you to easily grasp the mysteries of power transmission as you turn gears. Standing before this unique gear wall, you'll discover that each gear is not isolated. When you turn one gear, its neighbors move along with it, the power spreading across the wall like ripples. You can try different starting gears to observe the entire system's response; record different speed ratio combinations to experience the intricacies of mechanical transmission; and even change the transmission path to experience the joy of engineer-designed solutions. Most interestingly, you can invite friends to participate—one person turns one side, while the other observes the changes on the other, like engaging in a mechanical dialogue across space. In this process, you not only hone your observation and hands-on skills, but more importantly, you'll develop a completel
