This six and a half minute long video shows how to fold a square piece of paper into an hollow inflatable box or cube. Even simple origami projects like this one are just about impossible to instruct someone in using words alone, so a video like this one is the perfect way to find out how to do this project. Origami paper would make a nice box or cube, but any piece of paper will do. It is easy to square off a regular piece of typing paper and that works just fine. In just a few minutes you can have your own paper cube following these directions.
