additions for clarity:
I have a glass of ice (low physical entropy). I make a movie of the ice melting so that
it takes one hour to melt completely. Then I keep the camera rolling for another hour at
the glass of water. I compress them as mpegs and boom, the warm water by itself has
higher averaged physical entropy over the duration of the movie, but very little
information entropy and I wind up with a small file output.
It has lots of information - just not in a form you can record with a camera.

The first movie of the melting ice, with all of its nooks and crannies gradually
shifting and reflecting as it melts, slides, and floats in the water = heavy mpeg file.
Or you could run the movie backwards and make it seem like Shannon entropy is directly
proportional to information energy…it doesn’t matter.
