There is one where you can get two strings tie a knot at the top and, twist, twist, twist until the whole thing is twisted and then fold it in half (still twisted) and let go, then make another knot at the bottom.
it sound pretty hard but it took me about 30 seconds to make (literally!) and once you are done making it it looked like it was really hard to make!
They are called the Peace Bracelet!
Hope I helped in the way you wanted!
