Magic Tricks

I use it as a little hypnosis gag, where they read the text on the first page and after hypnosis they are not able to read. The text they just saw now looks like nonsens to them. I snap my fingers and they are now able to read the text again.

For that purpose it' great. You do need some misdirection but it's easy done by talking at the same time you give them the pad. They don't see the switch and they think that you just closed the pad and gave it to them so you can do the hypnosis. They open it again after holding it, so they don't suspect anything.
