For Zara’s party, I am going to be doing a few experiments with the guests. One of the categories we are going to touch on are Optical Illusions. First I am going to ask the girls to take a look at a few of these and then we are going to make the last one.

Can you see the old woman, the man and the young lady?

How many legs does this elephant have?

Can you see that the centre circles are the same size?

Can you see that all of the lines are the same size?

We’re going to make this one: when you spin the card, the bird appears to be inside the cage!
