Hi this is Scott Thompson from expertvillage.com, and today we are going to demonstrate how you can show a group of students that water actually has skin. First step that you need to do is to take some water and the eyedropper and start dropping it around on the plastic. Then if you just want to spread some drops out here and there. This is probably something that every kid has seen but never hasn't stopped to think about it. That the water really loves itself and doesn't really want to spread around too much. Putting it on plastic really helps show this. It maintains kind of a little half ball shape, and this is because water has skin. You can show how water loves itself by moving some of these drops over and combining them with other drops; as soon as they touch, they gladly join up into a a bigger drop. Water loves itself.
