I wanted to have a look at the engineering behind a heat actuated sprinkler head. It's interesting that the forces acting on the tiny glass tube are so well balanced that a slight expansion in the fluid causes it to shatter, a the same time being strong enough to withstand 20 (ish) pounds of force applied axially by a wide margin.✪► www.etsy.com/ca/listing/464202928/one-rule-to-ruler-them-all-cheeky-jokes ◄✪
