Which coffee cup is bigger?

Once you think you know the answer, move the left coffee cup to check!

This is called the Jastrow Illusion. This illusion happens when shapes that are the same size look different because of how they are arranged.

People think that the reason why the coffee cups of the same size look different when placed one above the other is because we judge their size based on the long and short sides of the shapes next to them.
