An early experiment
One early experiment, reported by the Chinese book Ten Thousand Infallible Arts of the Prince of Huai-Nan, was to blow out an egg and then push burning weeds inside it, so that the egg would fill with hot air. People said that the egg would then rise into the air, but this is probably not true. In any case, this project is a model showing the experiment.
How did eggs evolve?
