The fact that this chick's daddy is a Dr. further indicates this story is a joke....
The story may be a joke but let's not denigrate a 14 year old girl for her science fair project. Science fairs exist to give students a chance to experience how science is done, not to make paradigm changing discoveries on the cutting edge of human enquiry. Of course her doctor father new what the results would be. In all the science fairs I've been part of I've never seen a science fair project where I couldn't have told the student what the results were going to be before they started. It's not the results that are important for the student. it's the experience.
