Tardigrades Can Survive Extreme Cold And The Vacuum Of Space

Also known as "water bears," these microscopic invertebrates can enter a state of suspended animation, enduring temperatures from near absolute zero to over 150°C, intense radiation, and even the vacuum of space. They achieve this by dehydrating and forming a protective "tun" state, effectively pausing their life processes.

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.
