Today we had our first expert. She is a 75 year-old woman that we called "Nanny." She has Osteoarthritis in her thumbs. We brought her in, asked her some questions, and asked her to open some jars. the first time she attempted to open the vacuum sealed jar, it was impossible. The second time, after a hole was punched in the jar, she was able to open it, albeit with some effort. We also continued on our research, and started making a prototype for our project out of lego pneumatics.
