How Did They Build THAT?: The Genius, Hacks, and Glorious Mistakes Behind the World's Most Impossible Structures

You have walked past a miracle today.

The road under your feet. The house you slept in. The bridge you drove over. You never thought about how they stay up.

How Did They Build THAT? reveals the hidden genius, hacks, and glorious mistakes behind the world's most impossible structures.

From ancient wonders to modern marvels:
- How did the Egyptians lift 2.3 million stones with no cranes?
- Why does the Roman Pantheon still stand after 2,000 years?
- How do you pump concrete 600 meters straight up?
- How did two teams dig under the ocean and meet with 35cm error?

And the failures that taught us everything:
- The leaning tower that started tilting while they were still building it
- The 7 billion airport that forgot how to open
- The bridge that twisted like a ribbon and collapsed on camera

This is not a textbook. It's a collection of mysteries-told like a friend explaining a magic trick at a bar.

No engineering degree needed. Just curiosity.

Perfect for fans of Engineering in Plain Sight, Structures, and The Works.
