Domino is a generic gaming device that can be used in a variety of games. In particular, it is used for positional games, in which each player places a domino edge to edge against another in such a way that the adjacent faces are either identical (e.g., 5 to 5) or form some specified total.
Originally, dominoes were made of bone or silver-lip ocean pearl oyster shell, or MOP, with contrasting black or white pips, but they are now often made from hardwood such as ebony or ivory. They are generally more expensive than polymer-based sets and can be much more detailed in their design.
When a domino falls, it generates energy that travels down the line until all of the tiles fall. Some of this energy converts to kinetic energy–energy of motion–but most of it stays put in the first domino, which stores potential energy as it stands upright against the pull of gravity.
The Domino Effect
When you make a small commitment to something, it tends to cascade through your life like a series of dominoes. For example, when Jennifer Dukes Lee began making her bed every day she was committing to the idea that “I am the type of person who maintains a clean and organized home.” She did so in small ways, building her confidence over time until the habit became part of her everyday life.
