They provided a hosted callback in the clues. Just change foo to alert.

  The callback in the hints didn't work for me in the game, but the other suggestions here are working and quite eye opening ... That this works is really scary if not fully surprising: data:text/javascript;base64,YWxlcnQoMTMzNyk= Thanks jehna1 , sebslomski , all!
