Newtons Cradle Pendulum
Unique Gift
Executive Desk Toy
1.High Quality: The Newton’s Cradle is composed of a metal ball, a plastic bracket and a plastic base. Use nylon line of good material instead of cheap fishing line. With unique assembly design, the Newton’s Cradle is more stable and sturdy.
2.Longer Swing Time: Due to the resistance and friction of the air, the Newton’s cradle balance ball will continue to move for 10-20 seconds. You have enough time to observe the physical performance of the Newtons Cradle Balance Balls movement.
3.Wide Application: Suitable for children to learn and understand Newton’s laws of motion while playing this interesting gadget. Meanwhile, it is also an excellent desktop toy for the office, a good tool to relax your mind while you feel tired at working. It is a perfect decoration, whether at the office or at home.
4.Assembly Note: Firstly, gently open the package. Secondly, gently take out each component. Thirdly, align and install. Please be patient and careful during installation, as excessive force may cause entanglement!
5.Great Gift: Suitable for adults and children, a good toy for learning science, passing boring time, and releasing stress. There is no doubt that this is a good gift for birthdays and holidays. Easy installation, funny and educational.
Customers say
Customers find the Newton’s Cradle entertaining, keeping kids engaged for extended periods and serving as a good stress reliever. However, the build quality receives mixed feedback – while some say it’s a quality product, others report it falls apart quickly. Moreover, the functionality is mixed, with some saying it works perfectly while others find it barely functional. Additionally, the product comes extremely tangled and has issues with string length, and customers note it’s made of plastic rather than metal. The value for money is also mixed, with some finding it great for the price while others say it’s not worth it.

Do not buy
Product came horribly tangled. It was unusable try to fix it, but it broke. It was a disgrace to my bank account. One star do not buy. It was awful. had to throw away. It wouldâve been better watching paint dry but it made good kennel for fires

Good but small
Fun to watch, a lot smaller than Iâd thought it would be though

Small but great Newton’s cradle
It works prefect and I love the packaging so that I can put it safely in the box when not in use. I used it for teaching the law of cause and effect. I have seen others that get tangled up and are hard to move from place to place. this is perfect and compact and stores nicely for travel.

Buy at your own risk
Fine, but 4 of the connecting strings that hold onto the plastic came detached so I can’t drag a ball back without the string slipping off of the entire thing.

When it arrived in box strings and balls all tangled up and not working. I should return it but have great difficulty walking. So complete waste. Of money.
