Lots of science comes from amusing circumstances. Penicillin, for example, was discovered from someone saying, "You gonna eat that" to Alexander Fleming. Marie Curie was really just looking for a cool glow in the dark paint to make the ceiling in her bedroom have "stars!" And aerogel was created in 1931 due to a bet between two scientists. Ok, the first two were just jokes, but that last one is true. A bet led to the discovery of aerogel - considered by some to be the substance that will help humans reach Mars - and now you can get some for your very own!
