Okay, thank you. Water is quite beautiful to look at, and I guess you probably all know that you're two-thirds water. However, you may not know that two-thirds translates into ninety-nine percent of your molecules. Think of it, 99 percent of your molecules are water. So, do those water molecules actually do something or are they essentially jobless? And for that matter, are we even sure that water is H2O? We read about that in textbooks, but is it possible that some water is not H2O? These are questions whose answers are not as simple as you might think. In fact, we're really in the dark about water. We know so little. Why do we know so little? You probably think that water is so pervasive and such a simple molecule that everything ought to be known about it, right? Well, many scientists think the same. They believe that water is so simple that everything must be known. But in fact, that's not the case at all. Let me show you a few examples of things about water that we ought to know but really haven't a clue about. For example, have you ever wondered how the water gets into a cloud? Why does the water go to that particular cloud? And have you ever seen droplets floating on water? You would expect those droplets to instantly coalesce with the water, but they persist for a long time. And what about a lizard walking on water? The common idea of surface tension doesn't fully explain it. Here's another example: two beakers of water with electrodes in them. When a high voltage is applied, a bridge made of water forms between the two beakers. This bridge can be sustained as the beakers are moved four centimeters apart. How do we not understand this phenomenon? So,...
