But here goes...

Fries don't stay delicious very long. You get a couple minutes then they're blech. They don't work great out of drive-throughs, where you might take them home before eating, and now we have food delivery services where fries might sit 40 minutes before being eaten! Double blech.

This company made a coating for fries that makes them stay fresh for drive through service. That is old news. If you've had fries from fast food you've probably had these coated fries. People like them and don't know they're coated.

But that just covers a couple minutes... Could that company make a coating that keeps fries good for 40 minutes?

Awesome lady scientist says yes! Other people say no. Awesome lady scientist says, let's do it anyway!

They succeed. NPR Journalist does the Pepsi challenge on them - the fries are good. They're in the process of selling them to companies now.

Planet Money used to be a great source for learning about the economy but has recently become unlistenable. For example, I tried listening to their Halloween episode about recessions but gave up after ten minutes of bad jokes and audio "fluff".
