Newton's Cradle Colorful LED Light Desk Decoration

This device showcases the conservation of momentum and energy through a series of swinging balls. When one ball on the end is lifted and released, the resulting force travels through the line and pushes the last ball upward, or when one side is pushed, all the balls will swing together in a line. Swing one, two, or three end balls, and the changing colors will keep you entranced for hours with multiple color-changing modes, from blinking to cascading. You can place this device on your office desk, home desk, or shelf, making it a cool desk toy.

The device is made of glass, fishing line, and a plastic base, and it comes in the colors shown in the pictures. It requires 4 AA batteries, which are not included. The size of the device is approximately 12 x 9 x 12 cm (4.72 x 3.54 x 4.72 inches), and the package weighs around 185 grams.

Please note that there may be a 1-2 cm error due to manual measurement, and you should ensure that you are comfortable with this before placing an order. Additionally, there may be some color variation due to the different placements of the pictures.

The glowing Newtonian pendulum ball is even more brilliant at night, but the glass beads themselves do not glow. Instead, there is a glowing plate at the base that projects onto the top of the glass beads, creating a visually striking effect.

This device is an excellent educational science gadget, as it not only demonstrates a pendulum but also showcases the laws of conservation of momentum and energy. When you're feeling tired of studying or working, you can stir the balls to hear the clinking sound, which can help ease your mind.

Once the batteries are installed, the base board will light up, and the balls will appear colorful and beautiful, making the device very attractive. These glass balls are environmentally friendly and designed to last for a long time, making them great for home ornaments, study or office desk table decor accessories, and even as birthday gifts.
