In this week’s exercise, I tried adding flexinol into a felt fox’s tail. When the flexinol is heated, the tail will be slightly folded as if the felt fox is moving the tail. In the beginning, the flexinol is inserted into the felt. However, as wool is easily flammable, I moved the flexinol out and only connect it with both ends of the tail. Since I am using 9v battery directly, I also used a 10ohm resistor and a 4.7ohm resistor to control the heat and the folding time.
