The Newton's cradle — 5 fully metal suspended balls on a mirrored base. Dimensions: 12.7 × 10 × 7.5 cm. Concretely illustrates the principles of kinetic energy conservation and momentum transfer. An educational, decorative, and fascinating object — for all ages.
✦
Conservation of kinetic energyEach released ball transmits its energy through the stationary balls — the opposite ball rises at the same speed. Physics in its purest form, visible in real time.

5 metal balls · mirrored base · 12.7 × 10 × 7.5 cm · kinetic energy conservation
The Newton's cradle is one of the most hypnotic desk objects in existence — and one of the most elegant to explain. Release one ball: the energy travels through the three stationary balls and propels the fifth to the same height. Release two balls: two rise on the opposite side. Release three: three respond. This isn't magic — it's Newton. The mirrored base visually doubles the motion and turns every oscillation into a decorative installation.

To take it further: release 1 ball → 1 responds. Release 2 → 2 respond. Release 3 → 3 respond. Each configuration illustrates the conservation of momentum in a different way. The mirrored base allows you to observe the real movement and its reflection simultaneously — a doubly captivating effect during a demonstration.
The unusual desk object for physics enthusiasts: 5 metal balls, mirrored base, 12.7 × 10 × 7.5 cm. An original gift for a birthday, Christmas, office gift, or teacher gift — for any fan of science, decorative objects, or mechanical curiosities.
Frequently asked questions
What physical principle does the Newton's cradle illustrate?
The Newton's cradle illustrates the conservation of kinetic energy and momentum. When one ball strikes the others, energy is transmitted through the stationary balls and propels the opposite ball to the same height — and at the same speed — as the initial ball.
What happens if you release multiple balls at once?
If you release 2 balls together, 2 rise on the opposite side. If you release 3, 3 respond. This illustrates that it is the number of balls (and therefore the momentum) that is conserved, not just the energy. Some balls gradually stop due to damping from friction and air resistance.
Is it suitable for children?
Yes — the Newton's cradle is suitable for all ages. For children, it is a fun and fascinating object. For teenagers and adults, it is a concrete educational tool for understanding the principles of physics. The solid metal construction makes it robust and durable.
How long do the balls oscillate?
The cradle oscillates for several minutes before stopping due to natural damping (friction of the wires, air resistance). The more energy the balls are released with, the longer the oscillation lasts. The gradual damping itself is an interesting physical phenomenon to observe.
