Цепная реакция домино, , Domino Chain Reaction

A domino can knock over another domino about 1. 5x larger than itself. A chain of dominos 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). See for a sophisticated discussion of the physics.
