This is the conversation from the BBC World Service where we bring two women together who share an expertise and see what happens.
Today we're talking innovative textiles.
And when I say innovative, I am not kidding.
Think seaweed, nettle, orange peel, and clothes that are made in a single size but react to heat to fit the wearer or that change from warm to cool depending on the temperature.
Regina Polanco is the founder and CEO of Pyrotechs, a textile company making fabrics for some of the big biggest brands in fashion.
She was born in Vienna and grew up in Spain.
Sacha McKinlay grew up in Thailand and moved to the United States to study architecture.
Now a design researcher at Massachusetts Institute of Technology or mit, she's developing so called active textiles.
And I'm Elal Shamahi.
Ladies, welcome to the conversation.
Thanks for having us.
It's a pleasure to be here.
Thank you.
Very excited.
So let's just jump straight in.
Some of your textiles seem like they are straight out of a science fiction film.
I do feel like I'm in some ways hanging out with two inspector gadgets, but for materials.
So first up, do just each of you tell me the weirdest or the most wonderful item of clothing or material you have been involved in making.
Regina, shall we start with you?
Okay.
