I like that you sat and watched the girls in your house for an entire hour and tallied what they did. Your chart made it really easy to understand that hand washing is a huge problem! Your pictures of the kitchen are also really nice and give the reader a better idea of the set up of a typical sorority kitchenette.
I wish that for your interviews there would have been more quotes or question-answer formatted responses for easier reading. I do, however, like that you did dissect your interviews and gave some really in depth summaries.
What if instead of developing new gloves, there was a way to make a product that could be used to just rinse hands prior to cooking. I know a lot of cooks complain about how gloves actually hinder their cooking ability so maybe completely eliminating them would be a better option.
