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

Don’t buy bad quality
So cheaply made when and if it works it only lasts for few seconds and the threads gets tangled quickly it got tangled to the point its impossible to straighten it out again. Waste of money and time. Frustrating!!

Great teaching tool for classroom
This Newton's Cradle was a great teaching tool—my students grasped the concept more easily. Monitor use as the strings can tangle. It arrived promptly and was perfectly packaged.
