Coupled spring systems are fun and ubiquitous: in playgrounds, cars, and experimental physics lectures at universities. This Demonstration simulates the time evolution of three masses coupled with four springs. The left end of the first spring and the right end of the last spring are fixed.

maximal time — maximal evolution time number of time slices — the number of spring‐mass configurations to show initial position/velocity mass — initial position (horizontal) and velocity (vertical) of the point mass
