About this item
- Material: This product consists of 5 metal balls, plastic brackets, and plastic bases. The rope for hanging the ball is made of thick and wear-resistant nylon rope to prevent breakage. The reinforced assembly design ensures additional stability, making it capable of withstanding daily games and long-term displays.
- Easy to Observe Clearly: The unique design minimizes air resistance, allowing Newton's cradle balance ball to swing continuously for approximately 10 to 20 seconds. This extended duration allows us enough time to observe the motion of the Newton cradle balance ball, making it perfect for hands-on learning of physics or simply enjoying the enchanting sport.
- Use: This product is suitable for everyone to learn and understand Newton's laws of motion through interactive games. It is also a soothing desk toy for office workers to relax and unwind on busy days. It can also be used as a decoration to add a modern touch to home shelves, office desks, or classroom corners.
- Easy to Assembly: When installing this product, no tools are needed. Just align the bracket with the base, connect the pre strung balls, and finally fix them. Please be patient and careful during the installation process, as excessive force may cause the rope to become tangled.
- Popular Gift: This product is suitable for giving to people of all ages. It is education for young learners, stress relief for professionals, and fun for anyone. Perfect for birthdays, holidays, or as a unique science themed gift.

FAQ
What types of products does Stemora offer?
Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.
Are Stemora products suitable for children?
Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.
Is adult supervision required?
Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.
Can these products be used at home and in classrooms?
Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.
How can I check what is included with a product?
Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.
How do I know whether an electronic or robotics part is compatible?
Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.
When will I receive tracking information?
Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.
Why did my order arrive in separate packages?
Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.
Can I change or cancel my order?
Contact us as soon as possible at vaioamaonaoak@gmail.com. We will try to assist, but changes or cancellations cannot be guaranteed once an order has entered processing or has been shipped.
What should I do if an item arrives damaged, defective, or incorrect?
Contact us promptly at vaioamaonaoak@gmail.com with your order number, a description of the issue, and clear photographs of the item, packaging, and shipping label. Please retain the product and original packaging while we review your request. Eligibility and available resolutions are subject to our Return & Refund Policy.
