Origami Heart Cube by Francis Ow

How to fold Francis Ow’s modular Heart Cube from six 2X1 rectangles (three squares cut in half). Each module doubles as a heart card and when hit just right can do a back flip! Coincidentally, I happened to design this exact model a few weeks ago, but then I looked on the Internet and saw that it had already been designed a couple decades ago by heart origamist extraordinaire, Francis Ow. So, I contacted him and he kindly gave me his permission to teach it here on YouTube. Thanks, Francis, for this awesom
