How a Fire Sprinkler Works at 100,000fps - The Slow Mo Guys

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!

  • 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.

  • I accidentally set one of these off at one point. I was 10 meters up in the air on a lift doing some cleaning inside a factory when I bumped the mop head into the ampoule and it broke. It was an industrial grade sprinkler and I was at eye-level with the sprinkler head. It felt like, I would imagine, having a waterfall pelt you in the face. Needless to say, it took only a few seconds before I looked like I had been in a swimming pool as was fumbling to find the controls to lower the lift. Good times.

  • Could you guys video the Spotted Touch-Me-Not flower, they have seed pods that explode.

  • Gav is looking more like Flint Lockwood from Cloudy with a Chance of Meatballs with every new video.

  • Why is there a gap between the two streams of water after the ampule Bursts? and it looks like the first stream has a greater pressure when compared to the second! Is it because the water is pushed backwards during the explosion causing the force to multiplied! You should probably try using a glass or a clear tube! Amazing videos as usual

  • The metal where the water flows is specially designed to spray the water in a pre-defined pattern. Each model of sprinkler head has a different shape for differing spray patterns and water flow. It is also possible to have heads allowing dry powder extinguishant to flow - particularly useful where water in the pipes could freeze, or in restaurant cooker hoods where water could be severely dangerous. The red glass ampoule is a called a frangible bulb. Really good to see how it works - so thanks for the vid.
