How Little Things Can Make a Big Difference
A domino can knock over another domino about 1.5x larger than itself. A chain of dominoes of increasing size makes a kind of mechanical chain reaction that starts with a tiny push and knocks down an impressively large domino.
Original idea by Lorne Whitehead, American Journal of Physics, Vol. 51, page 182 (1983).
