What is a good example of a membrane?

A good example of a membrane is plastic wrap stretched tightly over a frame. One can also stretch a cut out of a party balloon over a frame to get a similar situation. Another membrane is well known to children everywhere: a thin soap film stretched over a wire loop used for making soap bubbles.
