The method is very simple and you don't even have to do much to carry out the trick!!

So heres how to do it:
First , tell your spectator to put his fingers of both hands into one another.  don't let any space between the two hands. Tell him to hold like this while you count 150 (in ur heart)slowly.
Look in your spectators eyes meanwhile.
After this, tell ur spectator to hold out the the index fingers of each hand.
Then tell that no matter what his fingers will touch. And the fingers actually will.
It has a great effect. and can really fool people so try it out..
