Theory #2

Have you ever wondered why Doritos chip bags have so much air in them?  Well, one day while out with Jenn, we came up with this theory.

First of all it is so that when you open the bag you can get a fresh burst of air.  Then second and most important is this:
If there ever was a tragic accident and all the air in the world was to go bad, all we would have to do is grab a bag of chips and open it to save the human raise.  See, it is all just a way of making sure that there is an ample supply of air in case of an emergency.
