Ever seen someone tear a piece of paper and within a few seconds witness it put back together? If you think about it, that is not possible. But if you know the secret of this magic trick, you can achieve the same results.
For this, you will need to prepare a few things. Lets say you are using a playing card and before you perform the trick, rip off already a piece of the card of the same color and suit you will be using to make people believe that is going to be the one you are going to tear.
When you are ready, place the card facing in front of you and fold it into four pieces. Crease it and then unravel it. While you are doing that, explain to those who are watching that you are doing this so the card can be torn evenly.
In essence you are holding two cards with the extra torn card piece pressed by your thumb onto the side of the card that is facing you. You rip down the upper middle piece of the card stopping at the center and then fold down the upper right corner and slide out the card which you ripped earlier making people believe that you just tore it in front of them.
To make the trick more believable, you rip it one more time by folding...
