7-UP Mind Reading !

[mackeye]

Hope this drives you as crazy as it did me.  I still haven't figured out how it does it!!
 
THIS ONE WILL BLOW YOUR MIND!
Can you figure out how this works? (I can't)

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. If you figure it out, let me know?

4) Preferably don't use zeros,  They don't always give an accurate Answer!
