Specifications

What's in the Box?

• 1 × Newton's Cradle (Fully Assembled)

Important Notes

• Handle with Care: This is a delicate decorative item. The metal balls are suspended by fine threads — avoid dropping or strong impacts to prevent thread breakage.
• Keep Away from Young Children: Small metal balls and thin strings present entanglement and choking risks. Not suitable for young children.
• Natural Motion Decay is Normal: Due to friction and air resistance, the swinging will gradually slow and stop over time — this is a beautiful, real-world demonstration of energy dissipation, not a defect.
• Easy Setup: To prevent transit damage, the product may arrive partially disassembled. Simply place the balls carefully onto the base before use.

Frequently Asked Questions

Q: Is Newton's Cradle suitable as a gift for kids or adults?

A: Newton's Cradle makes a great educational gift for older children (ages 8+), teens, and adults who enjoy science, physics, or stylish desk accessories. Due to the small metal balls and fine suspension threads, it is not recommended for young children under 3 years of age due to choking and entanglement risks.

Q: How long will the balls keep swinging?

A: The polished steel balls are precision-made to reduce energy loss, allowing for a long, smooth pendulum motion. Over time, natural friction and air resistance will gradually slow the swing — this is completely normal and is itself a fascinating demonstration of real-world physics (energy dissipation).

Q: Does it need any batteries or power to operate?

A: No batteries or power source are needed. Newton's Cradle is powered entirely by kinetic and potential energy — simply lift one (or more) of the end balls and release to set it in motion. It's 100% self-contained and ready to use right out of the box.

Q: What is the size of this Newton's Cradle?

A: This Newton's Cradle measures approximately 8.5 × 7 × 9 cm, making it a compact yet eye-catching desktop decoration that fits comfortably on most desks, shelves, or office surfaces.
