Today's word is "amphoteric" (Say "am-fuh-TER -ik"]. This describes things like iron, metals or other substances, which react with other chemicals as either an acid or a base, depending on reactive conditions. Wiki examples include some kinds of zinc and aluminum.
An acid simply is something "acidic," which often means anything -- when dissolved in water or some other liquid -- with a pH balance lower than 7, and a base is higher than a 7. This makes 7 the "neutral" pH descriptor.
Pure water is a 7. And slurpees are pretty close. This means the further (in either direction) you get from a 7, the less likely you are to want to drink it.
Coca-cola is unrated because, should it receive a rating, we would find out that it is amphoteric, and can rank as either a 1 (like battery acid), or about a 12 (like ammonia or bleach) on the pH scale -- meaning, given enough time, it could eat a hole through the earth half way to China.
Black holes are places where astronauts spilled their cokes into an unsuspecting galaxy. Bad things happened to their inhabitants. Scientists will tell you that there are no inhabitants in black holes. Gee, I wonder why.
