Sea Otters Hold Hands While Sleeping

Sea otters sleep floating on their backs in the water. To prevent drifting apart in currents, groups of otters — called 'rafts' — hold each other's paws while they sleep. Mothers are also known to wrap their pups in kelp to anchor them. Otters are one of the few non-human animals known to use tools.

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.
