Kept it cool as well as "safe"
Just a tad bit OT --hope the Super Mod doesn't mind-
When I was in High School, a smart guy drained one of the water tanks, and hid a booklet with info for the exam there.
During the exam that lasted for several hours he sneaked out to check his booklet.
In the meantime, someone had used the toilet, noticed the closed water plug and had opened it.
