“Camera Obscura”

A Camera Obscura is a dark room, with no light in it. The only light able to come through is through a small hole.i made my camera obscura using 2 cups.  i painted the inside of each cut black.  Then put wax paper covering the top of one cup  After that i taped the cups on top of each other.  Then painted the outside of the cups, and pocked a small hole on the top of one up and a bigger hole on top of the other cup.The first time i looked through my camera obscura, i seen upside down trees. I think that the camera obscura is a cool instrument.
