My daughter, the scientist

So my 4th grade daughter won first place in the school science fair. She gets to take it to the district. we ripped off Super size Me! We got a package of McD's fries and made some homemade with potatoes, salt and oil. Then we put them in jars and took pictures. The homemade ones, of course, looked foul after a few days. The McDs fries still look so nummy! I might eat them later tonight. They're weeks old.
