A zoetrope is an optical device that consists of a drum with an open top, supported on a central axis. A series of pictures on strips of paper are placed around the inner bottom of the drum. There are slots cut at equal distances around the drum, just above where the picture strips are to be positioned. The drum is spun to create the illusion of motion. A viewer can look through the wall of the zoetrope and see images change rapidly. Soon
Make paper strips the length of the inside circumference of the zoetrope and no wider than the space between the bottom of the zoetrope and the slots. Divide each strip into 12 equal frames.
Insert strip in zoetrope and gently spin
