Accidental Discovery

If all else fails, conveniently happen upon the answer, most preferably by resting your hand on it.

When somebody finds a helpful or dangerous tool, activator, or passageway without putting any conscious effort into their finding. In most cases of an Accidental Discovery being made, the one searching for this item or place either wouldn't be able to find it any other way or it'd take too much time for the creator to show them actively looking for it. The most common way to play Accidental Discovery is by having the seeker place their hand on the sought (and lean on it) while looking away, often talking to someone else that they're with.
