I remember this one.
Pretty cool.
But some people say that some trickery is done in the computer.

I tried this out, and when I typed "What is it?" in the images search, I just got redirected to the real Google images website. What did I do wrong?

You didn't do anything wrong. The idea is that you secretly tell it a card (ex: /7s/) and then it searches google images for 'seven of spades'.

You can type anything in to the search engine not just a card as long as you have / /. You can also change the web adress when performing if you can set up the window without people watching.

THis is awesome! I found this a while ago and I perform it at work all the time. Over and Over again. People are completely fooled by it. Everyone sees that google screen and assume that hey google wouldn't help by doing some trickery!

Amazing!

Thanks so much for this link. I just performed it with them thinking of a famous person they admire + Center Tear = Best reactions I've experienced in some time. Awesome stuff.
