There was a question in one of the service wide exams I took when I was in active duty. It was a promotion exam to go from E6 to E7. The question was:

Which one of the following is considered "the universal solvent"?

It was multiple choice. I don't recall all the answers provided, but the correct answer was water. So, water could serve as both a lubricant and a solvent, I guess.

Ok.. enough straying from the subject of the thread. Let's get back to the original subject and help this guy out.
