One Cut "Y"

This video teaches you how to make a block "Y" 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. A "Y" was chosen for BYU, or Brigham Young University. This pattern was created by the Compliant Mechanisms Research Group at BYU. For more detailed instructions, see this Instructable: https://www.instructables.com/id/One-...
