This looks great!  I tried to download and the iTunes store displayed a message that the app wasn't available in the US market.  Did you run into this problem?

I did not run into that probem.  I have it now in the cloud so that is where I get it from.  I will double check and get back to you.

It seems that this app is no longer available in the app store for the iPads.  So for those of you that were fortunate enough to have grabbed it then good for you, however if you were unable to get it then I am afraid it is no longer available.  I have looked for alternatives but haven't had any luck.  So book your time in the computer lab and try this out instead from PhET out of the University of Colorado Boulder . http://phet.colorado.edu/en/simulation/gas-properties
