1、Innovative Design: The pendulum ball features a unique wooden base and Z shaped N shape construction that showcases innovative design and unique visual effects. 2、Conservation Of Energy Model: Pendulum ball demonstrates the principle of conservation of energy model through impact and movement. It visualizes abstract physical concepts and triggers the audience's interest in conservation of energy, making learning more fun. 3、Balance And Stability: The pendulum ball maintains a balanced and stable state of the sphere through the balanced design and stability of the base. This stability enables it to maintain its specific motion state for a long time, allowing the audience to better observe and appreciate it. 4、Inertia Pendulum And Bumper Ball: In the process of swinging and crashing, the effect of inertia pendulum and bumper ball brings double enjoyment in visual and auditory sense. 5、Multifunctional Pendulum: Pendulum ball can not only be used as a decorative piece or desk ornament, but also can be used as an experimental tool for learning physics. Its multifunctional design makes it able to meet different scenarios and needs. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
