WebbIn this movie, they speed up the atoms of a person so that time is moving extremely slow, but not frozen. Trouble with this is that molecular motion and heat are linked. WebbFreezing can be done in a freezer, a chilled bath (shell freezer) or on a shelf in the freeze dryer. Cooling the material below its triple point ensures that sublimation, rather than melting, will occur. This preserves its physical form. Freeze drying is easiest to accomplish using large ice crystals, which can be produced by slow freezing or ...
