Description: This device is a perfect demonstration of the conservation of momentum and energy, featuring a series of swinging balls. Lift and release one ball at the end, and watch as the force travels through the line, causing the last ball to swing upward. Alternatively, push one side and all the balls will swing together in a line. With the ability to swing one, two, or three balls, you will be captivated for hours by the changing colors. This device offers multiple color-changing modes, from blinking to cascading, providing endless entertainment. Whether you place it on your office desk, home desk, or shelf, it will serve as a cool desk toy that will impress anyone who sees it.

The glowing Newtonian pendulum ball shines even more brightly at night, with a glowing plate at the base projecting onto the top of the glass beads. This educational science gadget not only demonstrates a pendulum but also illustrates the laws of conservation of momentum and energy. When you are feeling tired from studying or working, simply stir the balls to hear the calming clinking sound and relax. By installing batteries, the device will light up on the base board, and the colorful balls will look beautiful and attractive. These environmentally friendly glass balls are durable and designed to last a long time, making them perfect for home decoration, study or office desk decor, or as a thoughtful birthday gift.
