[hgohmzih] Replication of the volcano

Responding to criticism (e.g., xkcd 1611) that the classic baking soda and vinegar volcano experiment is not really science: one the fundamental tenets of science is that it can be replicated.  The result does not depend on, say, the whims of a god or the character of the experimenter, which is how people believed the world worked before science.  Replicating the reaction of baking soda and vinegar, showing it behaves the same was as it did in previous experiments, the way predicted by theory, is very much science.
