After having once seen it inside a house just before a thunderstorm, I've idly ruminated on whether or not I could create ball lightning. It was the only time in my life I encountered it (this was forty years ago). Let's figure out how to do that! Be a big hit at parties, I bet. It's got to be possible somehow. I guess you'd start with a #10 can of static electricity, and then I don't know exactly.
