Practical Engineering

Grady Hillhouse explains civil engineering — dams, bridges, roads, water systems — through hands-on demonstrations that make infrastructure fascinating. 5M subscribers understand why the Hoover Dam works, how stoplights are coordinated, and what holds skyscrapers up through Grady's combination of physical model demonstrations and clear explanatory narration. In 2026, his series on climate infrastructure (sea walls, flood barriers, wildfire prevention engineering) is the most relevant civil engineering content on the platform.
