Why do manholes steam?
The steam from manholes is actually the result of underground utilities, like steam pipes for heating systems, leaking warm steam. When this steam hits the cooler air above, it condenses, creating that iconic steaming manhole effect. It's not the Teenage Mutant Ninja Turtles making soup, unfortunately.

Actually, it's mostly just hot air and less about actual 'steam.' Sewer systems and the subway generate a lot of heat, and when it gets cold, you see that heat escaping through manholes as steam. So, yeah, cities are basically giant tea kettles in the winter.
Manholes steam because of the steam heating systems underground. Cities like New York use steam for heating buildings, and sometimes, the steam escapes through the manholes, causing them to steam. It's like the city's got its own natural spa treatment going on beneath the streets!
