Fire hydrants have been protecting cities for over a century, but have you ever wondered why they're almost always made of cast iron? With modern materials like stainless steel, aluminum, and high-strength plastics available, why does this centuries-old metal remain the standard? In this video, we'll explore the fascinating engineering behind fire hydrants, how cast iron became the material of choice, why its weight is actually an advantage, and how modern hydrants have improved without abandoning their original design. We'll also explain why fire hydrants come in different colors and what those colors can tell firefighters during an emergency.
