Great way to demonstrate kinetic energy - Excellent quality and packaging protected it. I bought this for the conceptual Physics class in our home school curriculum. The kids love it. Highly recommended. Review: Made with care. Packaged with care. Delivered with care. - Made with care. Packaged with care. Delivered with care. This is solid quality. It’s heavy and feels durable. Shipping was fast and is worth every penny spent. It was very easy to take out even though it was packaged very carefully with each ball in its own compartment and wrapped. It even came with an extra ball and string. Although it came with instructions, I was too excited to read, its easy enough that you can get it out and going without needing the instructions. I took my time and was careful not to twist or tangle anything. I don’t see this as a toy or something for small kids to play with as the strings are delicate and can get tangled if not treated with care. It looks good on my desk at work and from time to time I get it moving. It doesn’t last very long, but the sound is soothing. Spend the money and get it! ## Features - LONGEST SWING TIME：7 balls absolutely aligned with 50-60" swing time after cleaning the dust of balls - We guarantee swing 50s, contact with us via youtube with keywords of cerropi - NANO TECHNOLOGY： The swing lines are made of high-impact nylon manufactured with nano technology for ultra-thin yet extremely durable oscillatory support - SPARE BALL：One extra ball is included along with a manual on replacing the wire - 100% SATISFACTION GUARANTEE：Your purchase is completely covered by desertcart's returns and refunds policy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082CNJXXF | | Age Range Description | Adult/Kid | | Best Sellers Rank | #23,661 in Toys & Games ( See Top 100 in Toys & Games ) #235 in Educational Science Kits | | Brand Name | CERROPI | | Color | Black | | Customer Reviews | 4.6 out of 5 stars 1,467 Reviews | | Educational Objective | Logical Thinking | | Included Components | 1PC Newtons Cradle | | Indoor Outdoor Usage | Indoor | | Is Assembly Required | No | | Item Dimensions | 9.06 x 6.69 x 6.69 inches | | Item Type Name | science-kits | | Item Weight | 2200 Grams | | Manufacturer | CERROPI | | Manufacturer Maximum Age (MONTHS) | 720.00 | | Manufacturer Minimum Age (MONTHS) | 60.00 | | Manufacturer Part Number | 2056 | | Manufacturer Warranty Description | 60 Day Warranty Against Manufacturer Defects | | Material Type | Marble | | Model Number | 2056 | | Number of Players | 1 | | Operation Mode | Manual | | Size | Medium | | Supported Battery Types | No batteries required | | Theme | Home Decor | | UPC | 715668938236 746653837340 745245575738 | | Unit Count | 77.6027 Ounce | ## Images ![Newtons Cradle Pendulum with 7 Balls - Image 1](https://m.media-amazon.com/images/I/71eAqPCrm5L.jpg) ![Newtons Cradle Pendulum with 7 Balls - Image 2](https://m.media-amazon.com/images/I/61HCeTgnbeL.jpg) ![Newtons Cradle Pendulum with 7 Balls - Image 3](https://m.media-amazon.com/images/I/61NDODfNuJL.jpg) ![Newtons Cradle Pendulum with 7 Balls - Image 4](https://m.media-amazon.com/images/I/61O74GyEHFL.jpg) ![Newtons Cradle Pendulum with 7 Balls - Image 5](https://m.media-amazon.com/images/I/51fR6HP0gYL.jpg) ## Available Options This product comes in different **Edition** options. ## Questions & Answers **Q: i thought the entire purpose was to stay in motion until stopped . do they stop on their own?** A: yes, they will do stop on their own after 50-60 seconds **Q: Does this thing get rusted?** A: No. We have had ours for a few years now and it is still in like new condition.
