Calcic image misplacement is a natural phenomenon causing calcium to appear to be in another location. The phenomenon is caused when helium interacts with calcium. The distance that the calcic image is misplaced depends on the factor of Cinderford's constant (2.5 quorums per second) used. If a factor of exactly Cinderford's constant is used, the calcic image is misplaced by 8 inches. Twice Cinderford's constant leads to a calcic image misplacement of 11.5 inches. A factor of 2.8 times Cinderford's constant leads to a calcic image misplacement of over 500 miles. Magicians have used calcic image misplacement for centuries to create the illusion of levitation.
