Nigel stopped a while ago bumping into people or not. He did not care enough to remember even a few seconds ago of work. He just walked around the circle. Glaring at people to make sure they would not bump him. It seemed to be working marvelously.

Getting Sidetracked as Nigel usually does. Flamsteed must have some lungs on him to shout, talk, and run around a room and not get tired until some Gryffindor runs into him. Which was a genius way of being a air molecule by the way.

So Nigel has to explain either Boyle's Law or Charles' Law.

Hmm...how about option C. None of the Above and just hmm the ABC 123 song. sounded good to Nigel. Since an example of Mariotte's law is basically just the death of deep sea creatures due to change in pressure. Or simply the popping of a balloon.

Simple Enough
