Dominoes may seem like just fun and games. But understanding how they topple? That’s some serious science.
“It’s a problem that is so natural. Everybody plays with dominoes,” says David Cantor. He’s a researcher at Poly technique Montréal in Quebec, Canada. He has a background in civil engineering. So Cantor set out to study the blocks.
Domino games are more fun with a buddy. Research on them would be too, Cantor thought. So he teamed up with a friend. That physicist, Kajetan Wojtacki, works at the Institute of Fundamental Technological Research. It’s part of the Polish Academy of Sciences in Warsaw.
The pair used a computer to model a row of dominoes collapsing. It’s a chain reaction: Each falling domino topples into the next, then the next and so on. And the speed of that cascade depends on friction, they learned.
The friction happens in two places, the pair report in the June Physical Review Applied. The dominoes rub together as they collide. They also slide along the surface on which they sit.
Their computer model showed how best to get a speedy collapse. The fastest fall took place when they spaced slippery dominoes close together on a rough surface, such as felt.
David Cantor and Kajetan Wojtacki were inspired by domino videos made by engineer Destin Sandlin on his YouTube channel SmarterEveryDay.
