How to Fold a Secret Letter

Video Transcript

"Do you want to pass secret notes? My name is Robert Segundo and I'm going to teach you how to fold a secret note that nobody can get into, ever. So if we'll look down, you can see we've got our piece of paper here. We're going to fold it over in half, like so, and fold it down, like so. Now we're going to fold it in half again. Now what we're going to is we're going to take and we're going to fold one corner down into a triangle, like so. The same thing over here, like so. Now we're going to fold it over to where this meets up, like this. Actually no. We're going to fold it to where it meets up like that... there we go. We're going to do the same thing over here, the opposite side, fold it over like so. Now what we're going to do is we're just going to fold it in half this way, do the same thing over here, fold it in half this way. Now what we're going to do is we're going to take this triangle and fold it up, place it underneath that one, and then fold this triangle down, and actually wedge it into this side right here. There we go. And there you go, that's as good as a padlock. Nobody will ever be able to open this except the person you intend it for. My name is Robert Segundo, and that's a secret note."
