Answer to Question 1

The volume is less than one would expect simply by adding the two individual volumes.

Answer to Question 2

I think we might not be able to smell the peppermint. The reason I think this is that Mylar balloons usually last longer than the regular balloons (i.e. the air stays in them longer) so we might assume that the sub-microscopic holes in the Mylar are smaller, maybe so small that the peppermint particles can't escape. Note: Try it out in class or encourage them to try it on their own and report back.
