This video will teach you how to make a symmetrical 5 pointed star with only 1 straight cut. This is known as one cut origami. One cut origami (also known as one-cut, fold-and-cut, and magic cut) is a form of origami where you fold up a piece of paper, make one straight cut, then unfold the paper. Mathematical researchers have shown that any set of straight lines on a paper can be cut using this technique (with no extra cuts). Although technically every set of straight lines is possible, patterns exist for a butterfly, swan, turtle, and all 26 letters of the alphabet.
This technique was used in magic tricks by Houdini (and others). It is also rumored that Betsy Ross used this same fold pattern to create the stars on the first american flag.
