Draw a circle of any size without a compass!
Follow the directions from the video.
Tips:
Make sure it is the thumb's nail that is touching the paper, as it will be smoother and easier when rotating the paper.
To adjust the size of the circle, simply adjust where you are holding the pencil. The closer you are to the tip of the pencil. The smaller the circle will be.

NICE trick. Only one question: are you able with smaller circles too? I mean, that was a big circle, and I'm trying to do a perfect(sort of) Fibonacci Sequence.
