Any of 28 small oblong pieces marked with 0-6 pips, used to play games in which the players try to place their tiles edge-to-edge against those of their opponents so that the value of each tile matches either the total value of one end of a line of already placed dominoes or some other specified total. A domino is also referred to as a bone, a card, a tile, a spinner, or a ticket.

Domino’s has long been known for its pizza delivery, but it has more recently branched out into new markets such as takeout and carryout, and even grocery stores. The company’s focus on technology has allowed it to innovate in the way that it delivers its food and connect with customers, including new ways to order through text messaging or by using devices such as Amazon Echo.

While most people who use dominoes think of them as a simple toy that children play with, there’s much more that can be done with the little black and white rectangles. Many domino artists create intricate constructions of hundreds or even thousands of dominoes, lining them up in careful sequence and then letting them fall with the slightest nudge from one. Some of these impressive creations have been featured on TV and in movies, and others are set up as displays at parties and events.

We’ve all seen the videos of a domino effect — something that starts off small, and then just by tipping it ever-so-slightly, causes all the rest to cascade down in a beautiful chain reaction. While most domino effects are only a few inches high, there are also examples of enormous installations that require hours of patient work.

Today’s Wonder of the Day features Hevesh, an artist who has built a remarkable career on her skill with these little blocks. Her YouTube channel, Hevesh5, has more than 2 million subscribers. She’s also worked on projects for movies, TV shows, and other events, and she’s even helped set a Guinness World Record for the most dominoes toppled in a circular arrangement!

Hevesh uses her knowledge of domino to design and build tracks that can be used for domino art, as well as to make structures like towers and pyramids. She encourages people to use their imagination and plan out what they would like to see happen when their domino track falls — it can be straight lines, curved lines, grids that form pictures, or 3D structures such as walls. She says that planning out your domino art is a great way to help get an idea of how long a track will need to be before you can start building it.
