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.
