    Pumpkin Optical Illusion

    October 21, 2020 By Emma Vanstone Leave a Comment

    We’ve had a lot of fun today making Halloween versions of our optical illusion. What do you think of our pumpkin? Just roll the pencil or straw between your hands to see the face appear in the pumpkin.

    The best thing about this activity is that you be as creative as you like. Make a hat appear on a witch, a face appear on a ghost or even a bat hang from a tree!

    What you need for an optical illusion craft

    • white cardboard
    • pencils and colouring pens
    • scissors
    • glue/sellotape
    • straw

    How to make a simple optical illusion

    • Cut out two shapes from a sheet of white cardboard.
    • Draw whatever you want, if you don’t fancy a pumpkin how about a haunted mansion on one piece and a ghost on the other? Half of the illusion should be on one piece of card and the other half on the other side.
    • Glue or sellotape a pencil in between the two pictures.
    • Hold the pencil between your palms and rub your hands to make the picture spin around.
    • You should find the face appears on the pumpkin.
