Okay. So, this is our first stage.
Now, they are fixed but now the plan is to connect all the things with a rope.
And for that we need to make holes with a special device, and the candle.
We'll try to make holes.
Actually, I don't know whether it will work now,
because I never tried it seriously in this way, but let's hope.
So,
holes.
So,
it seems we
have all the holes are done.
And actually each vertex will be connected to four others.
So, there are two threads going.
So, we need four holes and we have made them, hopefully.
Okay. So, now we should balance things more or less to make
it symmetric as much as possible.
And then we'll try to make this with a thread.
So, let's see whether it goes through.
Okay. More or less.
Not completely.
Okay. We need a lot of thread.
So,our next stage is just connecting vertices
together, let me
try.
Actually there's a mathematical question.
So, each vertex is connected to four others,
and we need to make,
it is a kind of graph,
and we need to make a path in the graph which with it goes through all the edges.
It's called Eurelian path.
So, and we will know later why it exists,
but now it's enough that it exists.
So,
that's what we achieved,
and it seems more or less okay.
But the question is whether what is holding them
together is this potato side or the ropes.
So, to finally be sure,
we need to kind of cut the potato out.
Which is also a delicate
operation.
So, now we make clear all these things.
But then the question is how we can take the Potato out.
It should somehow get out but not destroying the entire thing.
Okay, like this. Oh, look!
Everything is perfect, you see that there are eight, this is an Octahedron,
there are eight triangle faces
and the big diagonals are made by these straws,
and you see that they don't touch each other,
and the entire thing is rather stable,
you see I can rotate it and move it and everything.
They don't each other anyway.
So, we have a Tensegrity,
and Buckminster Fuller should approve us now I guess. Thanks for watching.
Here's this ready thing.
So you see that there are three straws and they do not touch each other.
Now, it's not, in the video probably it was seen better,
but you see there's some space here, here,
and here, they really don't touch each other.
And if you want to see this cube,
you can look actually a bit different Tensegrity,
you can go to Wikipedia page and there is even animation.
So, compared to our example,
some things missing here.
There is one thread missing here and one missing here.
Topologically, now, if you add these to threads,
topologically the same construction.
But ours is more,
it's an Octahedron which is more regular.
But this is a narrow shape.
Okay. And here is the animation,
you can see how it rotates.
