What are knotted strings?

Knotted strings are strings that twist around each other in special ways, like when you tie your shoes or braid your hair.

Imagine you have a piece of string, it’s just one long line, right? But if you twist it around another string, you make a knot. It's kind of like when you wrap a gift with ribbon: the ribbon goes around and around the box, and sometimes it crosses over itself or loops back.

How knots work

Let’s say you have two strings, one is red, and the other is blue. If you take the end of the red string and loop it around the blue string, then pull it tight, you’ve made a knot. It's like when you tie your shoelaces together: they go from one side of your shoe to the other, twist around each other, and then come back, making a secure knot.

Sometimes knots are simple, like the ones in your shoes. Other times, they can be more complicated, like when you braid three strings together, it's like having three shoelaces dancing together!

You might not even notice them, but knotted strings are all around you, in your hair, your clothes, and even your toys!
