- Gav and Dan like learning and like fast things. In this episode, they learn about a fast thing.
A fire sprinkler that you can probably see above your head if you are watching this from your office when you should be working. Shame on you! Nah, just kidding. Watch more Slow Mo Guys at work!

Can you please do a video Of Jeremy axe kicking a desk in slow mo! You guys are awesome!
Loved this. Excellent job on the shots. Perfectly framed and informative.
SmarterEveryDay hi
How far away do you live from them that they just “borrow” the camera like that?
Hi can i get a shoutout
Destin, saw your video on laminar flow a few months ago. I'm really curious how the water spread would look if you feed the sprinkler with laminar flow.
Youre everywhere now 🤣 HI! 👋
Hello! Engineer for a company that makes sprinkley bois here!
I loved the graphic that popped up at 0:52 about the colors and temperatures. The "glassy, juicy ampules" (lol Dan) are called bulbs, and like the graphic shows, the color indicates the burst temperature. Several factors determine what temp bulbs you want to install, the main one being height. For example, the sprinklers at the top of a warehouse need to burst at a lower temp because of how far away the fire is, compared with a standard residential or office ceiling height. Sprinklers can also activate via "links", which are basically little plate springs that are held at tension by solder paste. The fire melts the solder, the spring explodes outward, water comes out. The explosive quality of the bulb or link is important, because you have to get everything out of the way of the water flow. Some sprinklers, known as nozzles, don't have anything holding the water back! More on that in a minute! One last thing: if you're in a building with a flat ceiling and don't see any sprinklers, look for round discs instead. These are known as coverplates, and they provide an aesthetically pleasing way to cover a sprinkler from view! They can be color-matched to any ceiling, and like links, contain a solder paste that makes them pop off and expose the sprinkler at a much lower temperature than would actually trigger the sprinklers.
Couple of myths: first one was one I used to think before working here is that the round bit on the sprinkler spins around as it goes off. Sadly not true for any sprinkler! That bit is called the deflector, and it's specifically designed to spread water in a certain pattern. Deflectors vary based on many factors, but primarily where the sprinkler is installed and the orientation in which it's installed. Many hotels use sidewall sprinklers with very different deflectors than the one in this video.
Another big one: sprinklers always have water immediately behind them in their pipes, like Gav and Dan's in this video. Also not true! SOME systems are like that, and those are basic wet deluge systems. The problem with them is that it's relatively easy to have an accidental activation, which is the SECOND worst thing a sprinkler can do, because water from sprinklers can cause lots of damage, but not nearly as much as a fire. The worst thing is obviously if there IS a fire and the sprinkler doesn't activate. All sprinkler companies go through GREAT measures to make sure neither of these things ever happen! Back to water in the pipes: systems that do NOT constantly have water behind the sprinklers are known as dry systems, and they rely on a trigger mechanism to open the VALVE on the water main that holds back water to the system. The trigger is typically one of three things: an electronic signal from a fire/smoke detector, a wet pilot line, or a dry pilot line. Pilot lines are located with the sprinklers in the protection area, and are pressurized with either water or air (wet and dry). When the fire trips the pilot line, the pressure on the line goes away, which trips the valve to open and converts the dry system into a wet system, but only nozzle sprinklers go off at this point. Most wait until the bulb or link sprinklers trip. Obviously the pilot lines trigger at a lower temp than the sprinklers; that way the sprinklers always have water behind them when they trip. Some valves have multiple of these fail-safes, to further ensure against accidental activation!
Any questions? I promise I can either answer you myself, or get a nice, smart coworker to help me out! Hope everyone is having a great day! 😊
So if one pops, do the rest of them pop too?? Even if it’s across the room?
@@derekmaestas8949 the head goes off in the area where the fire is(depends on the system) . So if the fire starts on the third floor ,the heads on the 1st floor won't go off. Hope this helps?
@@derekmaestas8949 only heads heated enough from the fire go off, so it’s localize. Number of heads that can trip without water pressure/volume dropping too low are dependent mostly on occupancy classification and the resulting design of the system.
Source, I’m a fire sprinkler fitter.
Thank you!! I really appreciated your explanation!
Adding a note to the lower temp sprk. at the top of a warehouse. Sometimes the temperature rating is higher to limit the number of sprinklers activating. If too many sprinklers open to soon, the water pressure drops below the design pressure for the anticipated number of operating sprinklers over the fire area, and then not suppressing the fire adequately. Otherwise, a good summary on fire sprinklers.

Fire Sprinkler fitter here 🖐️
Thanks for highlighting our industry. Fire Sprinklers save lives!
Fire alarms save lives, fire sprinklers save building foundations (and cause insurance claims).
Fire alarms provide initial warning, yes. But without sprinklers, the fire will spread and destroy entire buildings. Fire sprinklers cool the fire, if not completely extinguishing it, greatly extending the escape time for residents and the response time for firefighters, who often simply arrive at the site of an already extinguished fire and turn off the water. Furthermore, water damage to an isolated area is far less costly than vast fire damage and endangered lives, so insurance costs are much cheaper. That's why insuring a building with a fire sprinkler system is more affordable than one without.
Thanks for your contribution.
Having never seen one up close I was surprised to see the "fan blades" at the bottom were stationary. I had always thought each blade had a slight twist and they spun helping spread the water easier and possibly further. This was interesting to watch.
Word. Local 669
@@ajinsato9389 Same here bud.
The compilation of Dan’s flinches and “OH!”s at the end MAY or may not have been the best/funniest part of this video😂😂
I’ve also heard from building facility guys that the water that comes out of real sprinklers in building is usually gross old stale rusty water that’s been there stagnant for however long, and it’s not like in the movies where if you set one off, they all go off, each sprinkler is it’s own system
In really old buildings it gets to be black and sludgy and smells horrible.
@Ian Ostby actually it happens in every building no matter how old. That's why fire code requires that the sprinkler riser is flowed annually. I do this for a living😂
As a fire sprinkler inspector systems should be drained once to four times a year not to replace old water but to mainly check and make sure there is consistent pressure and no new restrictions in the underground piping. We also drain some water at what’s called an inspectors test to check alarms quarterly or annually as well.
i love how once again Dan takes the brunt of things and Gav is all "oh, bother me, a droplet has just hit my shoe. how outrageous!"
0:55 "155 American...things." Nailed it!
CHECKMATE! IMPERIAL SYSTEM!
I hate the American way
As an American I have been wounding with everything going on here are there country’s looking down on us now bc it pretty redundant
someone meme that
@@darkfire8615 cool
Being a sprinkler fitter myself, I can tell you that a sprinkler system usually has a normal pressure of roughly 60 psi, giving a much wider spread of water.
^ This is correct! 60psi or more!
I love that they called the possum cute. Possums are good, tick-eating friends.
We had one named Velcro. He was awesome.
His tail was like a snake that would wrap around your arm. 10/10 awesome critters
Not only do they eat ticks, also their body temperature is too cool to sustain ticks...so they do not carry or transmit them.
@@AricScooby Same with rabies.
The average shower head releases about 15 Liters per minute. A fire suppression sprinkler releases around 150 liters per minute. Hooking up a backyard garden hose to a fire sprinkler doesn't begin to do it justice.
Michael Bates shut up and enjoy the video Michael
I wonder how many litres of water a *Fire Hose* sprays out at its maximum pressure...
Ms. Nightshade normally run about 150 gallons a minute (568lpm) on our 1-3/4” fire attack hose lines.
Yeah I'd like to see the fire sprinkler spray water at full pressure
After witnessing a sprinkler go off, I can safely say that the water isn't quite that clean either 😧
1 millions dollars BUT you have to walk barefoot in Gavin’s backyard
I'd do it.
This comment belongs to RT. Wrong channel!
That's what I was thinking! Between this and the champagne bottles, there are a lot of of glass shards out there.
That all gets spent on "below the waist" replacement surgery.

I actually install these for a living and it's interesting seeing these actually go off in slow motion. And as far as the air that they are talking about, you're supposed to bleed the air before putting into service.
Also in real world applications that water is as black as oil for the first 50 gallons or more (and stinky).

I worked in a warehouse where someone hit a sprinkler head with his fork-lift. The first 983,645 gallons shot out in about 3 seconds and all of it was muddy brown with rusty water. The fire department had to come to turn it off, and the driver was sent out for a drug test XD

Yeah. I always thought the metal fans spun by the water pressure. But they don't. I'm satisfied.

water will forever be the greatest thing to film in slow mo, with fire being a super close second. i cant believe the same guy that is famous for bird noises and words like gubbins and munge, is here captivating me with these videos. good on ya Gav and Dan!
I would love to see lightbulbs getting destroyed by putting to much voltage trough them. We do have 20 to 2000W at our theater and I always wondered how it looks when they go in slowmo. In real-time it’s just a bright flash
Prolly would be hard to capture due to it being light, it is the fastest thing.
But the breaking of the wire does not necessarily happen in light speed. A bit like the lightning.
One time we had a lamp on without a shade on it and my brother threw a wet towel on the bulb( while it was still on) and the bulb exploded

After watching your video of you adding the SFX / Foley sounds you add in these videos. I can't help but start to tune in on it more. And I gotta say. Adding those DEFINITELY makes these more aesthetically pleasing.
i am actually a sprinkler fitter in Canada. judging by the size of that head, at proper system pressure, you would get roughly 10ft radius of water spray coverage. The air you see, even with the slow mo would be so fast that you wouldn't really notice it. You just go from dry to wet. Feel free to call the possum Yox.

Glad you didn't test with real sprinkler systems. No one ever tells you that the water is black when it first comes out...
In the older sections... yeah... but when you have coworkers left and right accidentally smashing the sprinklers setting off the system flushing the pipes it's not so bad.
That's only in older ones where the water has been sitting for a long while
Water is black in all of them. I'm a fire sprinkler inspector and have never come across one that when you first open the test valve the water isn't discolored.

theres something about slow mo water with that ambient noise in the background that is just so calming
i think filming a lasercutter would also give some nice footage.
"Hello guys, we're the slo mo guys and today...we're not actually dead"
I never owned one and I always thought they worked with electrical fire/smoke sensors.
We're alike
Sprinkler systems are tied in with the fire alarms by a flow meter. The flow meter will detect when the water starts to flow after the sprinkler head has activated then sending an alert to the fire alarm control board setting off the bells and whistles of the fire alarm alerting the occupents of the building. The fire alarm going off before the sprinkler will not activate the sprinkler heads.
Some systems are tied to electrical fire and smoke sensors. Most are just like this though.
Red Eagle they literally just invented heads specifically for warehouse storage that can be triggered electronically before the heating element melts/breaks. But they aren’t in use yet. There are literally NO heads right now or ever before that will go off without direct heat on the operating element.
@@redeagle2793 Some have a sensor-activated valve that opens to arm the system, but the sprinkler head is still heat-activated.
