This demonstrates the Laws of Conservation of Momentum and Energy — the total energy in the system remains constant. **Q: Is this suitable for young children?** A: This toy is recommended for ages 6 and up. The steel balls and strings require some care in handling. Adult supervision is recommended for younger children. It makes an excellent educational gift for school-age kids. **Q: What is the difference between Black M and Style1?** A: The Black M is the classic 5-ball Newton's Cradle with an ABS plating base and metal bracket. Style1 is a larger premium set with a metal + ABS construction, measuring 12.7 × 10 × 7.5 cm — ideal for a more prominent desk display. **Q: Does it require batteries or electricity?** A: No — the Newton's Cradle runs entirely on kinetic energy. Simply lift one or more balls and release. No batteries, no charging, no power source needed. **Q: What is EX-STOCK's return policy?** A: EX-STOCK Canada offers a 90-day return policy.
