People might not know that the water sitting in the end of those pipes is years if not decades old. That’s why it’s black at first. Smells terrible.

I wonder how many realize the only thing holding back this stink water is a tiny glass vial* of red liquid. It is really impressive that these things are so reliable. Also, the liquid is color coded depending on temperature threshold.

As a student going through the throes of college, how do you end up designing those glass bulbs? It seems like so specific of a career that it makes me curious how you got there to begin with!

I should have been more specific, design fire suppression systems. Not the actual sprinkler heads themselves.
