Kiln Studio

Kiln Studio makes long-form documentaries about the biggest things humans have ever built, and the ones we got wrong.
Bridges that shouldn't stand. Tunnels dug through mountains by hand. A city of twenty two million people sinking into the lakebed it was built on. Every video starts with a question that sounds impossible and ends with the engineering, the money, and the decisions that got us there.
No hype, no clickbait physics, no five-minute summaries of a Wikipedia page. Just properly researched stories about concrete, steel, water and the people who moved them.
New documentary every week.
