Whats in the Box?
One LED Light-up Newton's Cradle
Description:
Classic Desktop Display + Cool Light Show = Fabulous Physics!
Here’s a new take on a Newton’s Cradle with a twist- the spheres all light up and change color! How’s it possible? Just push the button and the multi-colored LEDs embedded within the glass spheres are powered through attached pendulum swing lines! Truly fascinating to watch whether illuminated or not! PLUS we've added a mirror to one side, doubling the optical impact! Some assembly required.
Requires 6 AA batteries (not included).
This device demonstrates Newton’s conservation of momentum and energy via a series of identically sized swinging spheres. When one ball on the end is lifted and released, the resulting force travels through the line and pushes the last ball outward.
This is great for my daughter, who hates sleeping with no lights on. She can have a bit of light and when she can't sleep she can get this moving and get something mesmerizing to watch!
