Wood Frogs Can Freeze Solid And Then Thaw Back To Life

These remarkable amphibians can survive having up to 65% of their body water freeze into ice during winter. They produce a natural antifreeze (glucose) that protects their vital organs and cells from damage, allowing them to effectively "hibernate" in a frozen, non-beating state until warmer temperatures return.

Natural rubber degrades primarily through oxidation — a chemical reaction with oxygen in the air. Cold temperatures significantly slow this process. According to van't Hoff's rule, every 10°C drop in temperature roughly halves the reaction rate. Storing rubber bands in the refrigerator (not the freezer) can extend their lifespan by years.
