A closer look

Flicking a single domino seems insignificant, but it is initiating a massive cascade of kinetic violence. Because each standing domino has stored potential energy, knocking it over releases more energy than it took to push it. Consequently, a tiny two-inch domino can theoretically tip over a progressively larger domino in the sequence, meaning a sufficiently long chain could easily topple a massive slab of concrete purely through amplified kinetic scaling.
