You stand on the sidewalk, neck craned all the way back, staring up at a skyscraper that punches through the clouds. How does something that tall not just tip over like a stack of blocks?

The secret starts deep underground, where you can't see it. Before builders stack a single floor upward, they dig down — sometimes ten stories down — and pour a massive foundation of steel and concrete. Think of it like an iceberg: the part you see floating above water is only possible because of the huge mass anchored below.
