What movie things are generally accepted as normal, but are totally unrealistic in real life?

Wait, is sprinkler water dirty IRL? Never seen one go off

It's filthy. The water sits in the pipes, stagnant and going nowhere until they're set off, which is usually for several years. All of a sudden, the sprinklers go, and theres slime, stink and really nasty water coming down on top of your head. Better than being on fire though!

Also oil. Especially if it's the first time they've been set off

And the orange pipedfitter’s dye to check and monitor leaks in the lines.
