Now we're ready to fold the image into its accordion shape, and then glue it to the white
paper. The first part, the end, should be face down, and then just go one to the other
as a fan shape, alternating the folds in and out, in and out. And then it all comes together,
and the last piece should also fold down, and now we have our accordion shape using
all the different strips. And what we're going to do is just size it up so that it fits directly
onto the white piece of paper. Now the white piece of paper is about half the size of the
entire image, because the--each sheet, each image is one sheet of paper, so we have to
basically take up half the space of the entire size. So we put the accordion shape on top
of the white image, now we see why it's important to have the two ends going down because they
have to attach to the end of the white paper. So if they were being folded up, it would
be a little bit more difficult to do that. So each side is facing down, and we get it
so that it's at the end of the paper. Each one should be at the end of the paper. And
then we can go ahead and glue each side. So, once it's folded up and has approximate shape,
I'm going to take the white paper. I'm going to apply some glue towards--to the end. Once
I have a nice line of glue going down the ends of the paper, I'm going to also make
some lines going across, and some going up and down. I want the folds, I want that to
hit the glue and have it stick to the paper, so I have to have the entire paper covered
with glue at some point because I don't know exactly where the folds are going to hit.
So I put it together, I--and I start by placing the first fold that's facing down, and I put
it onto the white paper, and I slowly open it up so that the accordion shape of my picture
has somewhat of an even space going across the white page. And then I end up with the
second end of the image, which is also being folded down--that should be hitting the edge
of the paper where I put my strip of glue. These spaces in between the folds, the little
triangles sticking up, should have a--should be pretty much the same size, and then you
know that it's sitting properly onto the white paper. That's why it's important also to put
glue at all different areas onto the paper, so that it sticks properly--that the part
that does touch the paper will have some strip of glue that will enable it to stay in place.
Looking at it from an angle, we see that once we see only one side of the strips, we can
actually make out one of the images. And now you can start to see the effect that we're
looking for as we put the folds back and forth, and we change the angle, we'll be looking
at it from an opposite side, and we'll see the second image. Now that the image is glued
onto the paper, and we see that it's nice and evenly spaced, we can now see how it's
going to look as we turn it from side to side, and we see that the image is interchangeable.
As it's going from one side, we see the turtle, and as we flip it back we see the folds showing
us the snail. So this completes the reversible image project. I've shown you how to do the
last step of taking the image that has been attached, the strips that have been attached
with tape, and we make them into an evenly spaced accordion and we glue it right onto
the white paper. And now, as we flip it back and forth, we can see each image coming out,
depending on which side you're looking from.
