Fingers-coupling hypnosis

It is not hypnosis but a trick a lot of "hypnotizers" use in order to assure people in their supernatural abilities. As a rule this trick is performed during the sessions of mass hypnosis. If you have ever seen some hypnosis shows, you should have noticed that it is a common trick that is performed at the beginning of the show. The aim of this trick is to make people believe in hypnotic abilities of hypnotizer.
So, that is how it is performed: a hypnotizer says that right here and right now he will prove everyone that he is a real hypnotizer. The words he says is also a part of a trick. Those words are pronounced in a special tone of voice and certain phrases are used. Actually, it is the psychological trick and it is always successful.
After the necessary words are pronounced the trick starts. In the same mysterious voice hypnotizer asks people to couple their fingers together and up their hands above their heads with their palms up. Once the hands are upped the hypnotizer starts its counting. He counts to thirty in a very slow manner. The slow manner is used as another trick.
The thing is that while you sitting with your coupled fingers above your head, you hands swell. And so, by the time he will get to thirty it will be a tough task for you to uncouple your fingers. Though, it is not the power of hypnotizer, but the powers of human's organism. It is rather hard to uncouple the swelled hands, and it has nothing to do with a hypnotizer.
