It's possible to knock the Empire State Building over with dominoes--all you need is physics
Physics is crazy, and some simple slabs of wood or steel can lead to a storm of released energy that is enough to knock just about anything in the world over with enough of them.
Domino Magnification is the effect where any domino can knock over another one that is about 1.5 times larger than the one before.
With this logic, you can use a domino the size of a brick, find another 1.5 times larger than it, and pretty soon, by the 32nd brick you'd have one large enough to topple the Empire State Building. The video included in the source is the perfect example of how a domino the size of a bean can knock down a 100 pound slab in only 13 steps.
