Hello, I really hope you can help me. I work as a resercher on a Tv-
program for children in Sweden. A child has asked this question, and 
what she means is that; if you fill a balloon with air (from your 
lungs) when you are inside your house and then takes the balloon 
outside the house (where it probably is a bit colder) it shrinks. Why 
is that?

THANK YOU VERY MUCH!
