A futuristic take on this classic desk accessory. Bright, multicolor LEDs in each glass sphere. You already know that the mesmerizing, calming motion of this 5-ball cradle demonstrates science in action. It's the single most addicting way to demonstrate Newton's law of conservation of momentum and energy, which makes it a great teaching tool, in addition to being fun to watch. After removing from the box allow the balls to hang freely for a few hours before use. This will allow gravity to tension the strings.
