A toppling domino can push over a larger domino, but how much bigger must the next one be?
The Small Knocking Down the Big is a 2009 installation by Chinese artist Qiu Zhijie made from hundreds of cut wooden dominoes meant to loosely demonstrate the effects of something that has become known as Domino Magnification. The basic premise is that any domino can knock over another domino that’s roughly 1.5 times larger, meaning that if you gently pushed a normal sized domino into a chain of bricks that increase in size each time by 1.5, the 32nd object will be large enough to topple the Empire State Building!
