About this item
Highlights
- Learn about Newton’s Third Law of Motion: For every action, there is an opposite and equal reaction.
- Watch how momentum and energy are transferred from one side of Newton’s Cradle to the other.
- Observe how potential (“stored”) energy becomes kinetic energy.
- Learn about matter, mass and momentum
- Learn about inertia, force, and centripetal force
- Observe what happens when you change the combination of balls you swing.
- Try simple experiments with coins to demonstrate Newton’s First Law of Motion: An object at rest tends to stay at rest; an object in motion tends to stay in motion

Junk
Absolute junk. It came extremely tangled up and it’s impossible to fix it. Even if I could fix it the strings are all warped and twisted. It won’t ever work. Don’t waste your money.

We’re sorry to hear about your experience with the Smithsonian Newton’s Cradle, Emmaly — that’s definitely frustrating. The strings should arrive properly aligned, and what you described isn’t the experience we want customers to have. Please reach out to our customer service team at custserv@nsi-int.com so they can help look into this and make sure you’re taken care of. Put “Target Review Follow Up” in the subject line and let them know you posted this review under the name Emmaly. We appreciate you taking the time to share your feedback.

My Niece Is Obsessed… and Honestly, So Am I
I grabbed this to show my niece a little physics, and now she won’t stop clicking it. She loves seeing how one ball knocks the others in perfect rhythm. Simple, calming, and surprisingly entertaining for both of us.
