11 Common Movie Tropes That Would Actually Ruin Your Life

4. Turning On The Sprinklers To Create A Distraction

Whether as part of a distraction or some kind of romantic movie climax, a fire sprinkler system is the perfect way to clear a building in seconds, preferably whilst the hero and the romantic lead share a passionate make-out sesh in the downpour.

In Movieland, all one has to do is light a cigarette or trip a fire alarm, and every sprinkler in the building spurts forth a shower of crisp, cool spring water,

In the real world, most sprinklers can only be triggered by a heat sensor and, even then, only the outlets in the direct vicinity will be activated. At this point they will release a torrent of filthy, stinking, black, stagnant water at a rate of 400 litres per minute (compared to the eight gallons of a normal shower). For the curious, this is what sprinkler water usually looks like.

If you want to clear a building, simply pulling the fire alarm is a much more efficient, much less stinky, way to do it.
