Camera Obscura Day

Leo and I made the most of a rainy day today and built a camera obscura in his room. We blacked out his window using cardboard & tape, and tried various hole sizes (.5 inch to project on a wall 12 feet away worked best) and ended up with an upside-down image of the view across the street. It was pretty dim, but we could make out a couple of trees. If you have no idea what I’m talking about, check here and here.
