Just went to a lecture at work on bubble science. Been looking at bubbles since childhood and never watched a single bubble long enough to see its whole life cycle as the soap weighs down and collects at the bottom. The top of the bubble gets thinner and thinner, changes color predictably, and then turns black before popping. Really cool physics on something I've just always taken for granted. I enjoyed the lecture. It also included lighting gas filled bubbles on fire so there was excitement too!
p.s. Tesla was awesome.
