I am always amazed at the ingenuity of the human mind. I've always been interested in and even fascinated by knots and tying. I've known several ways of tying shoelaces and did not give it much thought. I considered it so simple, once it was tied, the shoelace knot is one of the most basic knots. nothing to it.
Several years ago, when my son was in first grade I was awed by one of his classmates, a second grader, when I saw how she tied her shoelaces in a single, fluid motion. I asked her to repeat it and she did but her fingers always moved too fast for my eyes to catch the details of her action. The result, however, was the familiar knot. She told me that this is the only way she knew to tie her laces.
Then I came across this video and I learned how to tie my shoelaces in the same way.
It's not difficult and you can do it too and fascinate your friends.
