    Is it made from real astronauts?

    When my dad was a kid in the 60′s, freeze-drying was all the rage for preserving biological specimens.  With the help of Grandpa, he hooked a vacuum to a canning jar via freezer and attempted to freeze-dry a bird for the science fair.

    The way he tells it, the school cafeteria cleared out pretty fast when one of the other kids opened up the project for a closer look.  He stressed the need to create a strong vacuum and have low enough temperatures to complete evacuate the water.
