When you lift and release one steel ball, it strikes the stationary balls and the energy is transferred through them, launching the ball on the opposite end — all while the middle balls remain nearly still. It's a vivid, hands-on way to observe Newton's laws of motion in action.\u003c\/p\u003e\n\u003ch4\u003eQ: Are the balls genuinely stainless steel?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The 18mm balls are made from polished stainless steel, giving them the weight, durability, and smooth surface needed for accurate, consistent pendulum motion and long-term use.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this suitable as a gift or classroom tool?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely.
