Optical illusions and Light

In Room Four we are learning about light and optical illusions. When you put something like a pencil in a glass jar the pencil looks bigger . When you look at a picture of patterns which go big on the out-side and small in the in-side it makes your eyes go fuzzy.  Sometimes if light is too strong it an melt things such as plastic and crayons
I also learnt that if you get a piece of paper and cut out a circle and cut little triangles of coloured paper and glue them on, when you spin it around it turn out to be white. These are called colour spectrum spinning tops.
