Balance a broom any day

Meteorologist Alan Seals discusses the myth that a broom can only stand upright on the equinox. He explains that this is not true and demonstrates that with patience and balance, a broom can stand upright any time of the year. The myth persists because people don't try it at other times. Seals defines a myth as something often said but not always true.
