Brian: "Hey, Nilda, I was reading an article in Scientific American about self-cleaning clothing."
Nilda (facing the computer): "Self-cleaning clothing?"
Brian: "It said that lotus flowers have tiny bumps covered with wax that trap air. When rain falls on the that surface, the water and dirt are more attracted to each other than to the flower, and they both fall together. They're trying to use this concept to create clothing with small, synthetic bumps that will repel dirt in a similar way."
Nilda (turning around): "You need to buy stock in that company."
Brian (pause): "I'm going to write a blog about this."
