This is a video for an origami ball, or as it's sometimes called a water bomb and that's
because it uses the origami water bomb base.
The first step is we're going to start with the color side up and we're going to make
a book fold.
It's going to be with the white on the outside when we fold it up, and make sure that you
get all these edges to line up.
So we don't want to have it where there's extra color showing, get it where it's nice
and lined up, just white showing and then slide your fingers across the bottom.
That's a book fold, and then open it up and then do the other side for another book fold.
Next open the paper up, flip it over, so the white side is up and now we're going to do
diagonal folds.
So take the bottom point, bring it up to the top and again, make it as precise as you can.
Get it right on there, slide your finger down and then go out to the corners just like that.
Open it up and then do the other diagonal fold as well just like that.
Now go ahead and leave that last diagonal fold.
What we're going to do is put your fingers right here on the-- right underneath this
line right here up near the top of it.
And what we're going to do is we're going to rotate our hands up and you see how what
we're going to create is a base is this triangle base.
It's sort of, if you looked at it from the top what it makes is a bit of a pyramid, a
bit of a four-sided pyramid like that.
And once you have that shape go ahead and flatten it down, so that you have two flaps
on each side, and this is the water bomb base just like that.
Next we're going to take one flap.
There are two flaps down here, so don't take both of them, just one of them.I'm going to
take that corner and bring it all the way up to the top just like that.
Take this corner and bring it all the way up here on this side as well, so the left
and the right, and then flip it over and do the same thing on the back, on the left side
and the right side.
Next we're going to take this corner, right here and we're going to fold it straight over
into the middle, so it goes from this side directly into the middle line, and on the
other side, we're going to match it, so that it comes right up in the middle there as well.
And again we're doing the left and the right and then flip it over, and then do the same
thing on the back, and these should match up right along the same edge, as the ones
you did on the front side like that.
Now we're going to fold-- there should be two little extra flaps right here.
The points of the paper and we're going to fold both of those down, and fold them down
right into that same center spot, so all these flaps are coming in to reach together and
they're going to meet all in the exact same spot, right in the middle.
Flip it over and the same thing, and f you don't have those two little flaps they might
be on the bottom for you, so in case you can't quite find them.
There we go, so we've got all of that into the middle.
Now what we're going to do is we're going to use this as a little triangle.
There's this little panel right here.
So keep this, when this folds down keep that nice and flat on the back.
We're going to put our finger right underneath these two flaps, and you see these two little
triangle panels?
We're going to fold them over the top of these triangles.
Go ahead and fold them all the way over, and what we're going to do is we're going to take,
we're going to use this as a tab, this triangle panel and we're going to use this as a pocket.
And we're going to open this up a little bit, you see there's two flaps right in there.
What's going to happen is; and this takes a little bit of maneuvering; we're going to
take this panel right here and we're going to take it and we're going to put it right
inside that pocket, and push it all the way under there, so that locks it in real nice.
It's going to be all the way hidden inside.
So open up this panel again, pop it open so that you can find the two sheets in between
them and we're going to take that little triangle, and we're going to feed it inside there.
Locks it in real well.
And flip it over and I'm going to do the same thing here.
So go ahead and take this triangle, fold it down over the top first, so that gives us
the folds that we need to do this successfully.
And then open this back up, push that triangle inside and slide it under, so right here again,
we're going to open this up, feed that in and that's a really tight lock for each of
those.
It keeps it nice and flat.
Now next step we're going to take the top point and fold it down, and the bottom point
and fold it up, so that it makes a little square, and those are just preliminary creases.
Go ahead and open those back up, we're going to use those, but they don't have to stay
there.
Now here comes the fun part.
What we're going to do is we're going to open this up to a plus sign.
If you look at it from the top you can see how I've got all four panels, as far away
from each other as I can.
And this is important, because we don't want to do it-- you can't pinch or hold these down.
It won't quite work as well.
So open them up so that it makes a nice plus and one side has some holes on it, the other
side is sealed up.
We're going to use the side that has the holes on it.
And right there what we're going to try and do is we're going to put air inside the ball,
so go ahead and hold it up and blow into it, and make sure you put air directly into it
and it should pop up to make a nice little origami ball.
I'll show you one more time, as that's flattened down just like that.
