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

Dan from The Slow Mo Guys explores how sprinklers work, often seen in movies or public places. The video explains the mechanism where heat causes a liquid-filled ampoule to break, releasing water to douse fires. Using slow-motion cameras, they demonstrate the sprinkler's operation, highlighting the force and water pattern. Observations include the ampoule's role in holding a metal disk that releases water when broken. The video provides a detailed analysis of the sprinkler's function at various frame rates, offering insights into its design and effectiveness.

What differences were noted between the sprinkler that has been fired and one that hasn't?

How does the water flow from the sprinkler once the ampoule breaks?

What observations were made about the water's movement when the sprinkler activates?
