Diy fire suppression?

I used to design sprinkler systems...
If you were to take a large-ish bucket, attach a nipple to the bottom, and attach a sprinkler head to the bottom of that, you could drill a hole over the fire-prone area, and put the sprinkler head through, and it should work.

Sprinkler heads work because a cap is held in place by a piece of glass with alcohol in it (the little red part.) when that breaks, the cap is dislodged by the water pressure, and the water comes out. I guess you could even hook it up to a hose or something.

Interesting idea!!! You could probably find some sprinkler heads on ebay. I'd buy more than one so you can test it out first, but it should work.
