The Newton's Cradle — 5 suspended balls made entirely of metal, on a mirror base. Dimensions: 12.7 × 10 × 7.5 cm. Clearly illustrates the principles of conservation of kinetic energy and momentum transfer. An educational, decorative, and fascinating object — for all ages.
Conservation of Kinetic Energy
Each released ball transmits its energy through the stationary balls — the opposite ball rises with the same speed. Physics in its purest form, visible in real time.
5 All-Metal Balls
Heavy and precise metal balls, suspended on taut wires — optimal energy transmission and smooth, lasting oscillation.
Mirror Base
Reflects the movement of the balls and creates a captivating visual effect — the reflection visually doubles the animation and adds a premium decorative dimension.
12.7 × 10 × 7.5 cm
Compact size ideal for a desk, shelf, or display case — easy to handle and move for demonstrations.
Concrete Educational Tool
Illustrates physics principles — conservation of energy, momentum transfer, damping — in a fun and memorable way.
Unusual Deco-Science Gift
For physics enthusiasts, lovers of beautiful office objects, or original decorative accessories — for both children and adults.
5 metal balls · mirror base · 12.7 × 10 × 7.5 cm · kinetic energy conservation
Newton's Cradle is one of the most mesmerizing office objects available — and one of the most elegant to explain. Release one ball: the energy travels through the three stationary balls and propels the fifth one to the same height. Release two balls: two rise on the opposite side. Release three: three respond. It's not magic — it's Newton. The mirror base visually doubles the movement and transforms each oscillation into a decorative installation.

To go 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 mirror base allows for simultaneous observation of the real movement and its reflection — a doubly captivating effect during demonstrations.

Frequently Asked Questions
What physical principle does Newton's Cradle illustrate?
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 with the same speed — as the initial ball.
What happens if several balls are released at the same time?
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 thus 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 — Newton's Cradle is suitable for all ages. For children, it's a fun and fascinating object. For teenagers and adults, it's a concrete educational tool for understanding physics principles. The solid metal makes it robust and durable.
How long do the balls swing for?
The pendulum swings for several minutes before stopping due to natural damping (wire friction, air resistance). The more energetically the balls are released, the longer the oscillation lasts. The gradual damping itself is an interesting physical phenomenon to observe.

Great shelves, strong, secure, sturdy, decent size, unbeatable price.
Color: White, Number Of Shelves: 4, Size: 15.7in
Easy installation fits where we wanted them. Stable strong secure snug fit. Cleans easily with dust wipe. I would recommend buying these.

The shelves sag away from the wall overtime
Color: White, Number Of Shelves: 2, Size: 15.7in, Color: White, Number Of Shelves: 2, Size: 15.7in
Although the wood quality and finish of the shelf are clean and well-made, the main issue is that the shelves begin to sag over time while holding around 10 pounds, even though the product listing claims they can support up to 20 pounds. They may perform better on a brick wall, but on drywall you should be cautious.
To fix the problem, I had to purchase floating shelf brackets for support, which solved the sagging issue. However, this defeats the purpose of the “floating” aesthetic. Since the shelf is in my bedroom, I can overlook it, but I personally wouldn’t install these in a common area if I wanted a clean floating look.

Looks nice, easy to install
Color: Rustic Brown, Number Of Shelves: 2, Size: 22in
This shelf is lightweight, looks nice, and was easy to install. It comes with a little level to help you install it properly. There are plenty of mounting holes to choose from, so it is easy to screw it directly into a stud, or to just use holes that are convenient for you. It comes with a plethora of mounting hardware.
I mounted mine a bit high up and chose to mount it upside down so that I wouldn't see the three screws that hold the shelf to the mounting bracket.

Missing part , for an expensive shelf
Color: Ash, Size: 39.37 inches
I bought 4 of the led shelves , produced is missing mounting hardware. No measurement, instructions included. Tried reaching out with no response on getting missing hardware.
