‎ You'd be surprised to hear about it!‎

‎1. Cold wter differs from hot in sound‎

‎ It's true. It is really possible to determine what kind of water flows from the tap.

‎6. United Kingdom smaller than the US state of Michigan‎

‎9. Everest "added" a few feet‎

‎ It turns out that the first people who decided to conquer Everest, added a couple of feet to the height of the summit, so that the figure, in their opinion, seemed a little more plausible. The mountain was 29,000 feet (8,839 meters) high, but the researchers thought that because of such a flat figure, no one would believe it, so they added a couple more feet (8,840 meters). ‎

‎ By the way, thanks to the use of modern methods of measuring mountain peaks it was possible to find out that the exact height of the mountain is 8,848 meters! ‎

‎10. The fourth part of a person's bones are in the legs‎
