A domino effect or chain reaction is the cumulative effect generated when a particular event triggers a chain of similar events.
This term is best known as a mechanical effect and is used as an analogy to a
falling row of
dominoes
Dominoes is a family of tile-based games played with gaming pieces, commonly known as dominoes. Each domino is a rectangular tile, usually with a line dividing its face into two square ''ends''. Each end is marked with a number of spots (also ca ...
. It typically refers to a linked sequence of events where the time between successive events is relatively small. It can be used literally (an observed series of actual collisions) or metaphorically (causal linkages within systems such as global finance or politics). The term ''domino effect'' is used both to imply that an event is inevitable or highly likely (as it has already started to happen), and conversely to imply that an event is impossible or highly unlikely (the one domino left standing).
Demonstration of the effect
The domino effect can easily be visualized by placing a row of

upright, each separated by a small distance. Upon pushing the first domino, the next domino in line will be knocked over, and so on, thus firing a linear chain in which each domino's fall is triggered by the domino immediately preceding it. The effect is the same regardless of the length of the chain. The energy used in this chain reaction is the

of the dominoes due to them being in a
meta-stable state; when the first domino is toppled, the energy transferred by the fall is greater than the energy needed to knock over the following domino, and so on.
