Planet Money is a fantastic podcast that covers a huge variety of interesting topics, and only takes about 20 minutes. I highly recommend it as one of the most informative fun podcasts I've ever heard. 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.
