First, you need stones. Lots of stones. Each block for the Great Pyramid weighs about 2.5 tons. That’s like stacking a small car over and over.

Where did they get them? Quarries. Workers chiseled limestone blocks using copper tools. Yes, copper. Softer than steel, but they made it work. Talk about patience.

The Wet Sand Trick

How did they move these blocks over land? They poured water on the sand. Wet sand makes it easier to drag heavy stuff. It’s like sledding, but for boulders.
