That’s a really interesting question! I’ve done thousands of experiments in my time as a scientist and I can’t decide which outcome I like the best – when something I expected happens, or when something unexpected happens! My favourite is maybe the time that I was doing an experiment that was a yellow solution, and over about 5 minutes the whole solution turned to crystals. That was really cool!
I share my experience here:
I was trying to make lithium carbide from lithium hydride and carbon (graphite). I was always getting very tiny amount of impurity in my product. This impurity made me crazy in the beginning. It took me a while to understand that this result is really interesting. I am making some compounds that can be found in Li-ion batteries.
