Description
A classic science desk toy—and a hands-on lesson in physics. With one quick swing, kids can see Newton's third law of motion and the conservation of momentum in action: lift one steel ball and watch the energy transfer to the ball on the opposite end. Lift two, and two respond in perfect rhythm. This simple yet elegant device demonstrates the principles that shaped Isaac Newton's groundbreaking work. Complete with a collectible STEM content card, it's both a learning tool and a conversation piece that connects classroom science to everyday curiosity.
Now in updated packaging—same hands-on STEM activities inside!
