A very clever, yet easy to perform mental magic trick that gives the impression of real mind reading skills, but is very easy to perform. A small, multi coloured cube is placed inside a similar sized box by spectator (who secretly notes the top facing colour). This is done while the magician's back is turned - now the magician, under the pretense of reading the spectator's mind, names the chosen colour. The box is opened and the magician's revelation proved correct.
Nothing is added, nothing taken away. This is a very neat trick that can be fully examined both before and after the effect is performed.
