Try it.  It's puzzling and I've wondered what the answer is for many years...

The air inside your mouth is at body temp. close to 100 degress.  When you blow it out with your mouth wide open it comes out at that temperature.  But when you close your mouth down small, the air is compressed and then expands as it passes throug.  A gas that rapidly expands always cools (air conditioners and fridges use this principle).  There is a constant relationship between pressure, volume and temperature:  PV=nrT.

Actually, this has been something they've been testing for years.  It makes sense to me.  I think they need more research on it though.

To be honest I'm really not sure.  I'll have to pay attention next time.  \n\nI would be interested in hearing about your theory!

How do people come up with that?  Yes it really is amazing.  It boggles my mind to try to think of how someone figured all that out.  I dont think it proves anything about the book though.

Good luck with that. The odds of figuring out an answer with the information provided is a big fat ZERO. \n.
