In 1996, a unicorn that no one can see was adapted as a teaching device at [[Camp Quest]], the first free-thought summer camp for children established in the [[United States]], by Edwin F Kagin and the Free Inquiry Group of Cincinnati. As reported years later in the July 21, 2006 ''Cincinnati Enquirer'', "Campers must try to prove that imaginary unicorns—as a metaphor for God—don't exist."<ref name="Clark2006" /> [[Richard Dawkins]] alluded to unicorns in this connection in his 2006 book ''[[The God Delusion]]'', writing that "[[Russell's teapot]], of course, stands for an infinite number of things whose existence is conceivable and cannot be disproved.
