Newton's famous kinetic energy pendulum. This device demonstrates Newton's famous law of conservation of momentum and energy through a series of swinging balls. When one of the balls at either end is lifted and released, the combined force crosses the line and pushes the last one on the opposite side upwards; or swinging one ball to the side, will make all the balls swing together in a line. Swinging one, two or three end balls, and changing colours will keep you enthralled for hours - with blinking or cascading multiple colour modes. Ideal for your living room, home office desk or shelf. Get your focus back with this cool table decor. The glass balls are environmentally friendly, non-toxic and can be used for a long time. Excellent educational science gadget. It not only shows the pendulum, but also shows the law of conservation of momentum and energy.
