Title: Drying Dishes
In this Science Update, from Science NetLinks, you'll hear how a quirk of dish drying shows off a fundamental idea behind the chemistry of water. Because of their different compositions, plastic takes a lot longer to dry than glass. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.
