How do clothes get "staticky"? I mean, why do they stick and get static cling when you take them out of the dryer?
You have probably noticed that during the winter you can rub your feet on the carpet and then shock your friend (or sibling) by touching them, and that you can make your cat's fur stick up (and really annoy them) by rubbing your hand back and forth on their fur. What is common to these situations and the dryer situation? The act of rubbing and the dry climate are the common elements. When objects are rubbed together, charge may be transferred from one object to the other. Some objects like to give off negative charge and some like to receive negative charge, depending on the material of which they are made. The excess charge resides on the surface of the object (if it is an insulator) and causes the object to be attracted to or repelled by other objects, depending on their net charge. Thus, the object sticks to other objects. What does the dry climate have to do with anything? As you heard about in lecture, air is an insulator, but since water is a conductor, moist air is able to move charge from one place to another fairly easily. In dry climates, the excess charge residing on the surface of an object remains there until the object comes into direct contact with another object. In moist climates, the excess charge residing on the surface of the object is dissipated through contact with the moist air.
