How to Create a Mind-Boggling Optical Illusion
Sci-Tech Discovery Center at Home Experiments for Kids
Our brains are trained to look at patterns from a very early age. It’s how we are able to distinguish our parents from other people as well as being able to spot dangerous situations. When you see the long edge compared to the short edge of another piece, our brains quickly try to analyze the situation and conclude that the pieces are different sizes. In the following video, you can see how we transform paper into a mind-boggling, brain-fooling optical illusion!
To recreate this experiment at home, you’ll need:
• (optional) color
1. Start drawing out your design on paper first. Follow the shape that we have on video first and then experiment from there. You’ll want to make sure that you make a curved shape so that one side is longer than the other.
EXTENSION: How can you change the design for a new optical illusion?
2. Cut out the design you made.
3. Use the piece you cut out to make an exact copy on another sheet of paper. Trace along the edges with your pencil.
4. Cut out the second design.
5. You should have two identical curved pieces like the ones on the video. (Optional) Color your paper pieces in any color you want.
EXTENSION: See if you can affect the illusion more by drawing.
6. Fool your friends.
Using a little bit of science, we can understand how our brains and eyes work together…THEN trick them into false observations!
