Designed to be a waste of money!
Horrible! The way it’s packaged sets the cords up to be tangled as soon as it’s out of the box. Had to throw it away as soon as I opened it. Complete waste of money!

Decorative, relaxing, and well-built
This 7-ball Newton’s Cradle is a great desk decoration and surprisingly fun to watch. The balls are well-aligned and the motion is smooth, clearly demonstrating the physics principles in a calming way. I keep it on my office desk, and it always draws attention. The clicking sound is soft and not distracting, making it perfect for a work or study environment. The base is stable and setup was very easy. A great gift for science lovers or anyone looking for a unique desk accessory. Very happy with this purchase.

Genial
Tener un péndulo de Newton era un deseo de mi hijo, y estas navidades ha sido la ocasión perfecta. Había muchos modelos a elegir, y todos tenían algunas malas críticas que nos hicieron dudar en cual coger. Pero éste, ha sido todo un acierto. No es que dure mucho rato el movimiento ,pero a los padres, ya nos va bien que así sea..
