7 up can read your mind

Here's a bit of a mind game for you to end the week.

1) Go to the link below.  After reading each window, click on the boy in the lower right corner of the picture.

2)  In the last window type in your answer in the white box using the keyboard (there is NO cursor).

3)  Watch the paper in the boy's hand.  You will be amazed...and no, I don't know how it's done.

Here's your link.
