It is possible to build a domino chain that could knock over an entire building!

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 larger dominos.

A tiny domino that can hardly be seen can ultimately knock over a domino larger than the sun, if one could build dominos that large and stack them in order properly.

The first domino may only be an a subatomic particle inside of an atom, which then bumps into an atom, which bumps into a molecule, which bumps into a small Nano sized dust mote, which then bumps into; you get the picture.
