If we started with a 5mm tall domino, we could topple one the size of the Empire State Building within 30 dominoes of gradually increasing height. At an increase of 1.5 times each, specifically. The 1.5:1 ratio is a result of gravitational potential energy; by standing the dominoes up we put in energy and with the slight push from a small domino that energy is released in the falling of a larger one. And so on and so forth. It’s like a weird Katamari Damacy effect, and this video even shows it in slow-mo!
