eye illusions

This week Mr Johnson visited the class . he tolled us all about how are eyes can deserve us and how blinking can clean your eyes. And keeps it moused and if you wave a pen in front of your face it looks like its made from rubier. It is a trick that your eyes play on you we also made a toy with one picture on one side and the other one on the other side. sometimes your eyes see one thing but it needs time to imprint it in your memory.and we had to draw on on sides a fish bowl and a fish and when you spin it around you can see fish jumping into the fish bowl
