Later we went around to the exhibition stands and there were lots of good stands with projects. We saw a project with a lie detector and one about the play station that could make you more aggressive the more you play it. I thought they were good projects. My favourite was the lie detector because if you lie to someone it can pick up the lie, and the lie detector will tell you if what the person says it is true or false. It might be good to have in my class!
