Use this sign at qualifiers and touraments to remind the observing adults how to behave.


Many events allow one observer to be in the FLL judging rooms to record the session. However, too often these observers, having contributed 100's of hours, just cannot contain themselves. This sign gently reminds them to be invisible and unobtrusive.

  • This the "Observer Effect" in which "...simply observing a situation or phenomenon necessarily changes that phenomenon."  (See Article). I know this applies to Physics, but it's the same effect.
  • Gurning:  The sport of making funning faces (See article).
  • Harvey: An invisible rabbit.  "Harvey is a 1950 comedy-drama film based on Mary Chase's play of the same name, directed by Henry Koster, and starring James Stewart and Josephine Hull. The story is about a man whose best friend is a pooka named Harvey – in the form of a six-foot, three-and-a-half-inch tall invisible rabbit." (See article).
