Movies Get Fire Sprinklers WRONG! Here's How They Really Work #Shorts #engineering #moviemaking

How do fire sprinklers know when to turn on?

Unlike what you see in movies, most automatic fire sprinklers don't activate when they detect smoke.

Instead, a small heat-sensitive glass bulb responds to rising temperatures.

When the bulb breaks, pressurized water is released onto the fire.

Even more surprising? Individual sprinkler heads operate independently, meaning the entire building doesn't automatically get soaked.
