The experiment is regarding Jupiter's gravity, not Jupiter's environment. Everyone knows the lava lamp wouldn't work on Jupiter -- there's no electricity there.
I think this is fantastic -- it's encouraging to see someone taking the initiative to learn something for themselves, as opposed to just Googling/Wiki-ing it. I'm sure this all boils down to Mythbusters science, but even so, all I did in my hey-day was read comic books and play video games.
Well done, Mr. Fraser.
