A winding row of dominoes stands ready along a curved path. Click anywhere to tip the first piece — each domino stores potential energy while upright, and releases it as it topples, transferring just enough momentum to knock over its neighbor. This is a classic demonstration of sequential energy transfer: a small initial push cascades into a self-sustaining chain reaction that ripples down the entire line, much like triggers propagate in mechanical systems, neural signals, or even collapsing dominoes used to model exponential processes. Watch how the wavefront of falling tiles moves steadily along the path while the camera tracks the leading edge, and notice how each tile's fall speed and timing stay consistent link to link.
