In 2009, a world record of the largest toppling dominoes was set in Netherlands using a similar arrangement.
It seems impossible that a light push on a small domino in the domino chain is able to result in such a heavy fall by the last domino that is the size of a building. This is how it works. In a normal domino set up with equal sized dominos, some energy is lost to sound and heat, but the kinetic energy transferred from one domino to the next is approximately equal. In this domino set up, in which each domino is increasingly larger than the preceding domino, kinetic energy increases along the domino chain. Each increasingly large domino holds a larger potential energy because its center of mass is higher and has a larger mass, and thus, the potential energy that is transferred to kinetic energy as the domino topples over is also larger.
