A classic interactive physics toy that demonstrates the law of conservation of momentum. Perfect for hours of curious investigation! A must-have for the Science Cave!
Start a kinetic chain reaction with one ball causing the other four to move.
Pull back the polished steel ball on one end and let it fall. When it hits, it transfers its energy to the ball at the far end of the line, setting it in motion. This action raises an eyebrow… and curiosity. Further experimentation is automatic. Releasing multiple balls, in various combinations all at once, launches the curiosity and the fun for hours!
