Drinking Lucky Bird Perpetual Motion Bird Physics Toy Educational Products Perpetual Motion School Science Physics Experiment

Product does not include water cup
Because the kinetic energy of the drinking bird comes from two aspects: 1. The low-boiling point liquid inside the bird's vitreous body evaporates and condenses. The state change weight; 2. The external "weightlessness" due to the evaporation of the water in the bird's head breaks the balance and forms a cycle. sports. Therefore, the evaporation of water is a necessary prerequisite, and temperature and humidity (such as the rainy season and the warm and humid zone of the southwest basin sometimes do not move very smoothly) are the key conditions for evaporation, so drinking birds cannot drink water when the temperature is lower than 22 degrees. working normally.
