look up any word, like blumpkin:
 
1.
to show something true without yielding any knowledge of the cause, or without a logical basis or underlying tangible equation.

eymology: english "demonstrate", from latin "demonstrare," "to show completely", from de- (of, concerning) + monstrare (show)
A lot of people monstrate innate psychic abilities and even other psychics have no idea what's going on.

Monstrations are the exception to the norm, as science can explain nearly everything.

2.
the ability to turn into an inhuman creature (i.e. the incredible hulk or Lil' Kim)
