One is to make the powder so that you can't mix it with dirty water. Two is that we find a way to give clean water to everyone who uses the powder. Sam: Can we do both and still not make the price too high? We want to market it to the people who need it the most - the poor. And most of those people in those places are very, very poor. Vincent: A valid point.Well then, let's toss the first problem around a little.We can't make the powder so that you can't mix it with dirty water. The price will be too high, and people could get sick if they still try to drink it. But I think we can add something that would make the color change. Grace: Good idea. Like black or something. Nobody would let their kids drink something that didn't look like milk. Sam: I'm sorry, but I have to disagree. These people wash, drink, and even swim every day in the water that LOOKS dirty. But they do it anyway, because they're so poor there's no way they can get clean water. Vincent: That's true. Maybe we could add something that would make it smell bad too. If it smells bad and looks bad, that might make sure they don't drink it. But I don't know how much more it will add to the cost. |
