QLKUNLA Newtons Cradle Balance Balls Science Physics Gadget Desktop Decoration Kinetic Motion Toy for Home and Office

Very nice but beware of tangling nylon cords if used with too young of child.I recommend this for 8 yr old and up.

The media could not be loaded. 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.

Best cradle on the market. Crushes the simple National Geo and Classic Toy Store versions. Well built.

Very cute for your desk. It is small so it does not continue very long but I like it.

I was a little disappointed when I received as it’s of very poor quality and didn’t give the look I wanted. I kept on my desk anyhow as it did work and I didn’t want to spend a lot of money on a better one. After using it a few times it broke and ended up in the trash. I recommend to just spend the extra money for a nicer product.

I thought everything came in parts and I had to assemble the product myself, in an attempt to get things out of the center I tore 2 of the balls out of place and the rest of the wires got warped.

Just remember that it is a toy. It works very well as a toy.

This is a really nice one. The base is durable, and the balls have some weight to them. Much better feeling quality than I expected based on the price. The packaging for shipping was really good too. No tangling of the stings at all. I'm quite pleased.
