Pringles Houdini

Look at these two cans of pringles. To the untrained eye, they look exactly the same. In fact, one of these cans of pringles is worth FOUR TIMES as much as the other can of pringles! One of these cans of pringles is the can that Angela and I ate yesterday out of the minibar in our hotel room because we were too hungry. The other can of pringles is one that we bought at a convenience store for a quarter of the price to replace the minibar pringles. Can you tell the difference? ...Exactly.
