Facts 1201-1500

1201) Snails move at a steady pace with a maximum speed of about 50 yards per hour or 0.028 mph.

1202) The longest English words with no repeating letters are two 15-letter words: uncopyrightable and dermatoglyphics, the study of skin markings.

1203) When poured, hot water has a higher pitch than cold water. Water changes viscosity with temperature which affects the sound when poured.

1204) The vinculum is the line between two numbers in a fraction.

1205) The king rat can go longer without drinking than any other land animal; they can go their entire life of 3-5 years without drinking.

1206) The surface area of Pluto is only about 3% larger than Russia.

1207) Parts of Canada have less gravity than they should. Since gravity is a result of mass, varying densities of the Earth at different locations can affect it. However, the Hudson Bay region of Canada has a larger variation; the average resident weighs about a tenth of an ounce less than they would weigh elsewhere. The explanation appears to be the melting of the two-mile-thick Laurentide Ice Sheet which started melting about 21,000 years ago and is almost gone. The ice sheet left an indent in the Earth which means less mass and less gravity.

1208) On January 23, 1916, Browning, Montana experienced the greatest temperature variation ever recorded in a 24-hour period going from a high of 44 degrees to a low of -56 degrees Fahrenheit for a 100-degree change.

1209) Owyhee is the original English spelling of Hawaii.

1210) About 1 in every 200 people is born with an extra rib called a cervical rib which forms above the first rib at the base of the neck just above the collarbone. You can have a cervical rib on either or both sides, and it can be a fully formed bony rib or a thin strand of tissue fibers.

1211) When a flea jumps, its acceleration is so intense that they must withstand 100 times the force of gravity. Humans pass out at about five times the force of gravity.

1212) Between 1853 and 1859, New York spent $7.4 million buying the 843 acres for Central Park; while, the United States spent $7.2 million in 1867 to buy Alaska which is 663,268 square miles or 424 million acres.

1213) There is enough stone in the Great Pyramid of Giza to build a two-foot-tall by four-inch-wide wall around the entire Earth.

1214) According to research, zebras likely evolved to have stripes to avoid biting flies. In an experiment, horses wearing a striped pattern coat had far fewer flies land on the them than horses wearing a solid color coat. The flies spent the same amount of time circling regardless of color, but far fewer land with stripes.

1215) Less than 1% of bacteria cause disease in humans.

1216) The human body is bioluminescent; it is just too faint for our eyes to see. A 2009 study found that human bioluminescence in visible light exists; the human body glimmers, but the intensity of the light emitted is 1,000 times lower than the sensitivity of our eyes.
