It is pretty cool to think about how people would use the things that they hade it is a lot different from today . I mean people hade problem solving thinking that thinking gave people the iron . The iron was this thing that people would use to make there close nice and not wrinkly and I don’t mean a iron that plugs into the wall you hade to put it on the fire place and heat it up . But know  you just plug it in to the wall and then there you go. They very  were smart and great problem solvers .
