An optical illusion is a visual trick that deceives the brain into perceiving something different from what is there. They are a great way to learn about how brains work.
We had a lot of fun creating a Christmas version of a classic optical illusion.
What do you think of our Christmas Tree? Just roll the straw between your hands to see the decorations appear on the tree.
If you don't want to draw your own, my optical illusion template is free! Watch the decorations appear on the Christmas tree, and the snowman get a face, buttons, and arms.
You'll need:
- white cardboard or thick paper
- pencils and colouring pens
- scissors
- glue/sellotape
How to Make a Christmas Optical Illusion
Cut out two shapes from a sheet of white cardboard, or use my festive optical illusion template.
Draw whatever you want. If you don’t fancy a Christmas tree, how about a fireplace on one side and presents on the other, or Santa on one side and a chimney on the other?
Glue or sellotape a pencil between the two pictures.
Hold the pencil between your palms and rub your hands to make the picture spin around.
How optical illusions work
This is the same concept used for making cartoons. Still pictures are moved very quickly to create an illusion of movement.
If you design your own optical illusion, I would love to see it.
