Klein bottles fabric climb balls fit on your head.

If you start taking this inside out, I notice.

So you pull it inside out and keep going.

Keep going.

Keep going.

Eventually you get a shape that remember, this is same same bottle where the fabric is going in one direction and the other direction it's There's a circular hole where my finger touching this part of the manifold is going left.

This finger is going to the right, so there's a round hole around here.

Okay, I looked at that and I said, I'll bet that that's related to what in topology is called across Cap.

I looked at and I said, OK, that's nice to know.

So one day I'm over here doing the laundry free.

Come here, check this out.

So I'm doing the laundry one day, and I were I reach in and pull out my genes.

Well, my jeans see a lot of service and I pull it out and I look a TTE the pants like and well, if there's a hole in the knee, I know that I'll keep wearing it.

But the pants leg has pulled through its hole so that it goes up along here and down long here.

No words.

If I had it the right way out, if I hadn't been pulled inside out, you'd be Justin ordinary pants leg with a hole in it, but popped out of the dryer looking like this when I looked at it and said, Wait a second.

This shape here where one side is going this way.

This side is going this way.

It's the same fabric shape.

There's a head with this.

Okay, so I said, Hey, I could probably make a clang bottle out of this pants leg.

All they have to do is cut it across here and bring it around so it together.

Okay, so I start with this cut off a leg right there.

So now we have a pant leg with a hole in the knee in this funny shape.

What?

I'm calling across, Captain.

I think it's a total logical cross kept I have to do is bring this around into a fell Seem to get this.

I know.

Have a This hole has gotta be the same if this whole this pathway up here is the same as this pathway up here.

This is a denim Klein bottle that you can make and the way to make it.

If you don't want to use Denham, is you say OK, find a shirt or a pair of pants so you have a shirt that's, you know, no your usual J random shirt and start by cutting the sleeve off.

Cut the sleeve along here.

No, I have the ingredients for a climb bottle.

There's the whole that was in the sleeve.

The cuff.

I'll bring this.

Bring the cuff through the hole.

I know have that interesting cross cap going up this way.

Going down this way.

Bring these around so that the shoulder part is sewn to the cuff and that'll make declined bottle.

So this is the way.
