As she builds a display, Hevesh works on one section at a time. She then tests each section to make sure it falls properly. She films the tests in slow motion, which allows her to make any corrections.
Finally, she connects each section using lines of dominoes. But she omits a few dominoes here and there, until the last minute. That way, if she or a teammate accidentally knocks something over, it doesn’t bring the whole installation crashing down. “I’m pretty good at preventing big accidental topples, but small ones happen in just about every project,” she says.
When it’s time for the final run, Hevesh is usually a bit nervous: “I worry constantly that something will go wrong. Once the last domino has toppled, that’s when I can finally celebrate and sigh in relief.”
