Today we had a lot of fun making Halloween versions of our staple. optical illusion. What do you think of our pumpkin? Simply roll the pencil or straw between your hands to see the face appear on the pumpkin.
The best thing about this activity is that you can be as creative as you want. Make a hat appear on a witch, a face on a ghost, or a bat hanging from a tree!
New this year is a FREE optical illusion template!

How to make a simple optical illusion
- Cut out two shapes from a sheet of white cardstock.
- Draw what you want. If you don't fancy a pumpkin, how about a haunted mansion in one room and a ghost in the other? Half of the illusion should be on one piece of cardboard and the other half on the other side.
- Glue or tape a pencil between the two images.
- Hold the pencil between your palms and rub them together to make the image rotate.
- You should find the face that appears on the pumpkin.
If you design your own version, I'd love to see it.
