Rusting of Steel

My science project was about two nails one was put in water and the other without water. My hypothesis was that the nail without water was going to rust faster, but my hypothesis was wrong. The one in water rusted faster. I thought it would take 10 to 15 days for it to start rusting. It only takes 96hrs or 4 days to start to rust. My conclusion is that the nails are made up of 96.75% of iron and when that combines with water and air it forms rust.
