to experience true CR2032 powered fnord, you have to have a bunch of them all up together in the same vessel experiencing short circuit+thermal runaway.
back when I worked on Hell Island I mean at the children's museum in Miami, one of our education staff who didn't know any better set out a bunch of CR2032's for an LED blinkies construction activity. they poured a large number of the batteries loose into a plastic bowl.
I came along a couple minutes later as criticality was just being achieved. I grabbed the now smouldering bowl and ran outside with it just as the bottom melted out and the batteries began to pop off like Satan's Tiddlywinks. At least three or four caught about 30 feet of air and pelted a bus that was departing the nearby bus stop, and I had to put out a very small resulting grass fire by stomping it out
