A tiny bird delivers a payload of cash! A revamped version of the bird in equilibrium is now available, featuring some innovative tweaks. Check out this video for more details: https://www.youtube.com/watch?v=H6dfGqJgsVQ This clever design maintains balance due to its center of gravity being positioned just beneath the beak. The model consists of two interconnected parts that can slide smoothly, allowing users to pinpoint the exact balance point. The front component's weight is determined by a pair of coins, making this setup incredibly flexible and eliminating the need for complex calculations. To operate the model, simply assemble the two parts, load them with some cash, place them on a small tree, and then gently slide them until equilibrium is achieved. It's a fun and interactive way to grasp fundamental concepts like gravity, balance, and center of mass, making it an excellent teaching tool for exploring these ideas.
