MIRAGE? Or Not?

There are pictures of different hamburgers on the menu.

Magi clearly shows both hands empty, then rubs his hands on a favorite hamburger picture.

And pulls a REAL hamburger from the board, the picture is now GONE!

Or is this just a Fast Food Mirage??? !!!

You can now show both sides of the menu board, it has to be a Fast Food Mirage

Except the mirage did happen and you take a bite of the REAL hamburger.

 Does not require an assistant.
