Perhaps, optical illusion and magic are no different from each other for both share the same effects: they amaze and fascinate and deceive the human eye.

A suspecting audience will lose the chance of catching the trick if you are perfectly endowed with sleight of hand skill and interest.

Your eyes can be deceived both by magicians hand dexterity and apparent psychological persuasion (patter). The apparent patter of a magician combined with quicksilver hand skill is a perfect match to a dubious crowd.

Practical Optical Illusions

Optical illusions can be carried out in front of a large or medium size audience or can be performed using pictures especially if you have no immediate contact with the person you are trying to communicate with.

Pictures that visibly change their color or physically modifies along the way to keeping a long stare at them or by following simple rules or instruction helps you baffle your friends and amaze them of your ingenuity.
