- 1.71 lb Heavy-Duty Build for Stable Desk Use: Designed to feel solid, not flimsy. This large Newton’s Cradle features a 235g solid wood base, sturdy metal frame, and a total weight of about 1.71 lb / 775g, helping it stay firmly anchored on office desks, teacher desks, and home workspaces while the balls swing.
- Solid Steel Balls for a Crisp, Satisfying Click: Built with 500g+ of high-density steel ball and frame components, this physics desk toy delivers a clean rhythmic motion and a crisp “click” sound. The heavier steel spheres help demonstrate momentum transfer more clearly than lightweight hollow-ball desk toys.
- Tangle-Free Packaging with Simple DIY Assembly: To prevent the heavy steel balls from tangling during shipping, the metal frame and wooden base are packed separately. The easy DIY assembly design helps your Newton’s Cradle arrive neatly and keeps the strings aligned for a better first-use experience.
- Real Physics Demonstration for Classroom & Home: A visual way to demonstrate Newton’s Laws, conservation of momentum, and energy transfer. The cradle swings is a realistic teaching tool for physics teachers, STEM learning.
- Sophisticated Gift for Office, Science & Stress Relief: With polished steel spheres and a classic wooden base, this Newton’s Cradle works as executive office decor, a calming desk toy for adults, a physics gift for students, or a unique gift for bosses, coworkers, teachers, dads, and science lovers.
