Showing that their material has a breadth of applications, and can be worked into different shapes and contexts?

To be clear, they used their invention to make a shoe.

Shoes get literally kicked around a lot. It’s a good form factor for demonstrating durable, flexible strength. Just show it kicking something that would shred a lesser material.

The silk is also hard for bacteria to break down. So maybe as a shoe it would be less smelly than other fabrics over time?

It's probably extremely expensive, so you need to use it in very high value products.

I have no idea what we should make with it, but we currently make clothes out of it:

Leather was a pretty great invention too.

Maybe a really fast slingshot?

It's just a concept shoe made from spider silk. There can be many more application.

It's biodegradable (I guess) so probably we can use it to replace plastics.

Instead of plastic or metal or wood, we might end up using proteins.
