Im sure you all have seen the card trick on ebaums world. If not, heres the link:http://www.ebaumsworld.com/trick1.html
I was extremly bored, and nothing to do. So I went to ebaums and looked threw some stuff. I never went to the Magic section before. So I check it out. I take the card test, followed the instructions, and walla! My card disappered.
Heres how they did it. They take a random amount of cards. Like this picture
Now they say that they are predicting the card.
Now after that. It looks like this.
If you look at the 2 pictures closely. None of the cards are matched. And you desperatly look for your card. Ignoring the others.
Once again, I found this out by boredom.
