Optical Illusion Lunch Box Notes

They have wings to fold back with answers written on one side. You can write your note on the back and fold up to hide the answer.

Set 1 has questions like 'which line is longer?', 'which dot is bigger?' with simple graphics. Once kids find out the unexpected answers, they can measure the sizes or distances to confirm it. For the shades of grey question, you can cover up the surrounding area to see how they fool your eyes.

Set 2 has distorted and moving dots and patterns illusions. Print these on the finest quality paper and color setting for best effect.

We've also created some printable papers with optical illusion patterns you can use to make cookie wraps or treat bags — a whole lunch box full of visual entertainment!
