hey guys what's up Jeremy Shafer here
check out my new favorite model that I
designed recently this I call a
knick-knack it's a imperfect polyhedron
because well that's together but this
isn't so we're gonna close this up and
uh oh that opened up so we'll close
these and oh no that opened up and it
just goes back and forth like that it
makes a cool sound and it's a little
doodad toy I call a knick-knack want to
learn how to fold it
Ready Set here goes all right so for
this knick-knack I'm going to use a ten
inch square of Kami you could use a six
inch square or you can even use a
sheet of printer paper cut square but I
like having two colors on it because I
think it looks better so let's begin
white side up first step is to divide
the paper into thirds so let's first
form an S so bring the left side behind
and the right side in front and now it's
all about just fiddling with the folds
until they line up so they have to line
up here and here I noticed that I'm a
little bit short here so I'm going to
push this front edge to the left and
then slide the back edge up and that's a
little better now I'm going to slide the
back edge and just fiddle with the folds
until you have it perfect here and
here and when it's perfect make those
two pinches and unfold now fold this
corner to this pinch mark make sure that
these edges align perfectly and flatten
all the way across now turn over top to
bottom and fold the bottom edge to the
top
okay so we divided it into thirds and
now unfold and notice we have a mountain
and a valley let's fold the mountain
onto the valley so pinch the mountain up
and fold it onto here make sure it
aligns perfectly and when it does
flatten and when you flatten you see you
make this fold right here
okay now let's turn over top to bottom
and fold in half so the right side is
the thicker side when you pull it in
half make sure that you hold the layers
together so that nothing slides just try
to make it as perfect as you can alright
now we're going to make a paper airplane
fold so let's fold this flap up so that
this edge aligns with this edge and
flatten and repeat on this side it
should be easier because it's thinner
and now unfold those two flaps and now
we're going to open this thick side
right here just lift up the front layer
and we're just going to fold this
interior flap like this on the existing
crease okay and close it
now we're going to open here this is
kind of a tricky step not really though
we're just going to turn this page right
here turn it over like that and flatten
so it should look like this okay
now rotate and fold this flap how far?
We want the fold to align with this edge
and on the sides you can align this
point to this corner and this point to
this point and now turn over right to
left and fold this flap up make sure it
aligns perfectly - okay now comes the
fun step
let's open here and now grab on to this
central flap and you're going to pull
the two edges apart so it's just like
this
carefully slide them apart and flatten
and here believe it or not we have an iso-area twist fold isn't that a cool way
to make it so now we're going to fold
let's see first rotate and here we have
a central line let's fold this edge to
that line make sure you hold the layers
down so they don't slide
and rotate and repeat on this side and
unfold now this model is is't area
meaning it's the same thing on both
sides so let's turn over and here we
have the central line so rotate so it's
horizontal and now fold this edge to the
center line and rotate and do the same
thing on this side and unfold okay so
here we have a 1 by 2 rectangle let's
fold the corner of this rectangle up
like this and do the same thing on the
opposite corner here's the 1 by 2
rectangle and fold it up and since its
ISO area we're going to do the same
thing on the other side so turnover and
here is the 2 by 1 rectangle fold the
corner up and same thing on the opposite
side
all right now we're going to fold not
this corner but we're going to jump two
units one two and fold this flap up so
that it points in the same direction as
this flap and rotate and do the same
thing here's this flap one two and fold
this flap up and here we go let's do it
on the other side turn it over and
there's the corner one two fold this
flap up and rotate and one two and fold
this flap up alright now it comes a kind
of tricky step let's fold this flap
fold this flap under behind like this so it's
like that and now that exposes this flap
and fold it up like this so it's like
that and now we're going to do the same
thing here so holding here just take
this flap and fold it down and now that
exposes this flap and fold this flap
down
and now turn over and we're going to do
the same thing so let's start here fold
this flap under like that and fold this
flap up and now do the same thing here
so you have to hold it down like this
inside and fold this back down so here
we have a ninja star let's turn it over
a couple times
voila and voila I don't think will fly very well cause it has flaps all
over the place
alright now we are going to make a
reverse fold on these two flaps so let's
open right here and just push this flap
inside on the existing creases and
flatten
okay and let's do the same thing on this
one so open here and push it down and
flatten okay before we do the other
side we're going to do a series of folds
on this side so let's take this flap and
fold it over and that exposes this flap
this flap has to go underneath this flap
so lift this big flap up and that goes
there and refold the big flap and now
take this corner and bring it down and
that exposes this flap this flap has to
go underneath this big flat like that
and close it again and this side is done
so we have flap on this side and now
well you can pull that up either
direction is fine let's turn over and
we're going to do the same thing on this
side but it's a tiny bit trickier so
let's first do the reverse fold so open
here and reverse fold it close and
rotate and reverse fold the side and
close okay here we go
let's fold this flap over and now this
flap needs to go into a pocket which
pocket? not that pocket we want to do the
top pocket so open that just like that
and just hold it in you can first fold
this edge inside and then just kind of
nudge the whole flap inside like that
and now bring this flap over to the
other side and now that exposes this
flap and it has to go into a pocket
which pocket
this topmost pocket not there but there
and fold it in just curl it in and close
and we are actually done well not quite
but we're done with the spinneroo so
hold these flaps out like this and try
to make them go perfectly at 90-degree
angles like that and you can hold it
like this
loosely. this works better with 6-inch
paper but it'll fit your hand better too
and then just blow on this part right
here that's pretty good so there's the
spinneroo all right now for the
knick-knack all you have to do is... this is
kind of tricky... is holding right here
you're going to pull this flap out while
pushing on these two points so pull it
out and push and that opens it up into
this pyramid like thing and now rotate
it and hold here and pull on this point
as you push these together just kind of
pull it out
come on it might be a little bit tricky
but eventually it'll click into place
and there it is and that is the Knick
knack so it's also called the imperfect
polyhedron and what's cool about this
model is that it can also be a perfect
polyhedron
if you push these two and these two at
the same time and let go you see it's
the perfect polyhedron but then once you
push these together like that and those
two open up and now push on these two
and that opens up so it's like this and
I like that it makes that really nice sound
sometimes the sound is a little bit
sharper that sounds like a frog or
something and that looks like a fish
like that "Crooooak" alright well I hope
you guys enjoyed folding this I just
love this I could do this for hours I
probably have and I like how it looks
like it's made from modular origami and
it's a toy it's just fun and then when you
want to put it away you can just
collapse it back like this and stick it
in your pocket
and then when you want to play with it
again push here and here and and there you have it alright I hope you guys liked
that and you guys later bye bye
