The Twirler

I made a Twirler for my science experiment. I made it out of paper, rubber bands and pictures. I cut the paper into a circle and put a picture of a fish on one side and a fish bowl on the other side. Then you twist the paper tightly.  When you let the paper go it spins so fast that it tricks your eyes to make it look like one picture, that the fish is in the bowl.  This is easy to make at home, sometime you should try it.
