Tardigrades Can Survive the Vacuum of Space and Extreme Radiation

Also known as water bears, these microscopic invertebrates can enter a state of cryptobiosis, shedding nearly all their water and forming a "tun." This allows them to endure temperatures from near absolute zero to over 150°C, making them virtually indestructible.

Normally hidden in healthy, alert cats, it becomes visible when a cat is drowsy, ill, or under stress. Humans lost this structure through evolution.

Rubber Bands Last Longer When Stored in the Refrigerator

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.

The First Item Sold on eBay Was a Broken Laser Pointer

In 1995, Pierre Omidyar created 'AuctionWeb' (later renamed eBay) and listed a broken laser pointer as a test. It sold for $14.83.
