How do FIRE SPRINKLERS Work? (slomo)

how do you stop the water if you accidentally break one

In response to the top comment... There was a device I had seen several years ago that I am now unable to find. No joke, but I think it was called "Dam it". You would get soaked trying to use it, but the plug was on some sort of extension rod and you would wedge the plug in between the diffuser and the orifice. If it meant saving valuables from water damage because of the accidental discharge of a head, getting soaked would be the price you pay instead of waiting on the FD.

So the head of it is spinning because the water is shooting right on it?

Can a high powered green or purple laser set one off ? As some lasers can pop balloons or light matches?

should not be messing with a sprinkler

the fluid is mercury

Shoulda used an upright head if u we're gunna have it in that position

most liquids contract when frozen.
thats a property of water

thx for your demonstration

any chance of doing this again with the new toy ?

awe man, I thought you were going to make a flamethrower sprinkler :/

What is the plug called that is released?

Liquid e. Alcohol

The title is kinda baity, you make it sounds like a sprinkler that shoots fire, was somewhat disappointed

pretty cool

whenever we change heads we always keep the old ones to scrap. one day we got bored and made some water bombs with these tied into a 12 inch nipped of 1" filled mostly with water and then pressurize them to like 40 pounds and break the link or bulb in a guys truck.

I'm curious - if you were to accidentally set one of these off, is it possible to plug it with your finger until someone's able to get it turned off so that the room doesn't flood?

i am very disappointed since i thought it was gonna shoot out fire. :(

I am very high and expected sprinklers to shoot fire.
