This is a nice visual effect, which can stand by itself, or be incorporated with other magic effects. Use it in conjunction with some other trick, like the Metamorpho Spots or Polka Dot Silk. Or use the fan as a running gag. It is used as a magic fan for every trick to make the magic happen. After a couple of tricks the magic does not work. So you change the number of spots to increase the magic power! A few tricks later you repeat this again. With a little imagination you will be able to work this cute effect into any type of magic act.
