Drawing the perfect Circle

Is it really possible to draw a perfect circle, with no guidelines?… Is the question I received from one of the students at Towey. I decided to show them that it was quite possible as it is super fun. We started with our blank sheets of paper, I instructed the students to make a circle motion in the air. They were to then move closer and closer the their paper while still make the motion; as they reached the paper the perfect circle was formed. They all laughed because they saw how simple it was; afterwards, I thought the students shading and balancing light and darkness to create a ball on a tabletop.
