Air Space

There are only two more days before we head for New Zealand. I am looking forward to the farm, the beach, seeing friends, and the food. It will be a LONG flight, but I am even looking forward to that. Most of my packing is done, and I am down to the "what did I forget" stage.

During our shopping, we bought some of the storage bags that you fill with clothes and then squeeze the air out of so that your clothes take up much less room in your luggage. They really do work, and since we take LOTS off stuff, we need all the help we can get. This got me thinking about how much air space there is in other common substances.
