I am in my 40s and almost every day it still pops back into my head how freaking amazing it was in high school chemistry watching water in the beaker above the bunsen burner stay the same temperature while all that damn energy went into the phase change.

I also have a pond in my back yard as a hobby. The ice has pretty much all melted now, after a lot built up during the very cold weather we had a while back. But holy hell, I started up the waterfall pump while there was still ice in places but water could flow. I had big slabs of ice that were in MOVING water and did not melt for DAYS because the water was almost the same temperature. It looked wrong, but the energy just wasn't there to do otherwise.
