- Sound travels 15 times faster through steel than through the air.
- On average, half of all false teeth have some form of radioactivity.
- Only one satellite has been ever been destroyed by a meteor: the European Space Agency's Olympus in 1993.
- Starch is used as a binder in the production of paper. It is the use of a starch coating that controls ink penetration when printing. Cheaper papers do not use as much starch, and this is why your elbows get black when you are leaning over your morning paper.
- Sterling silver is not pure silver. Because pure silver is too soft to be used in most tableware it is mixed with copper in the proportion of 92.5 percent silver to 7.5 percent copper.
- A ball of glass will bounce higher than a ball of rubber. A ball of solid steel will bounce higher than one made entirely of glass.
- A chip of silicon a quarter-inch square has the capacity of the original 1949 ENIAC computer, which occupied a city block.
- An ordinary TNT bomb involves atomic reaction, and could be called an atomic bomb. What we call an A-bomb involves nuclear reactions and should be called a nuclear bomb.
- At a glance, the Celsius scale makes more sense than the Fahrenheit scale for temperature measuring. But its creator, Anders Celsius, was an oddball scientist. When he first developed his scale, he made freezing 100 degrees and boiling 0 degrees, or upside down. No one dared point this out to him, so fellow scientists waited until Celsius died to change the scale.
- At a jet plane's speed of 1,000 km (620mi) per hour, the length of the plane becomes one atom shorter than its original length.
- The first full moon to occur on the winter solstice, Dec. 22, commonly called the first day of winter, happened in 1999. Since a full moon on the winter solstice occurred in conjunction with a lunar perigee (point in the moon's orbit that is closest to Earth), the moon appeared about 14% larger than it does at apogee (the point in it's elliptical orbit that is farthest from the Earth).
- Since the Earth is also several million miles closer to the sun at that time of the year than in the summer, sunlight striking the moon was about 7% stronger making it brighter. Also, this was the closest perigee of the Moon of the year since the moon's orbit is constantly deforming. In places where the weather was clear and there was a snow cover, even car headlights were superfluous.
- According to security equipment specialists, security systems that utilize motion detectors won't function properly if walls and floors are too hot. When an infrared beam is used in a motion detector, it will pick up a person's body temperature of 98.6 degrees compared to the cooler walls and floor.
- If the room is too hot, the motion detector won't register a change in the radiated heat of that person's body when it enters the room and breaks the infrared beam. Your home's safety might be compromised if you turn your air conditioning off or set the thermostat too high while on summer vacation.
- Western Electric successfully brought sound to motion pictures and introduced systems of mobile communications which culminated in the cellular telephone.
- On December 23, 1947, Bell Telephone Laboratories in Murray Hill, N.J., held a secret demonstration of the transistor which marked the foundation of modern electronics.
- The wick of a trick candle has small amounts of magnesium in them. When you light the candle, you are also lighting the magnesium. When someone tries to blow out the flame, the magnesium inside the wick continues to burn and, in just a split second (or two or three), relights the wick.

- Gorillas sleep as much as fourteen hours per day.
- A biological reserve has been made for golden toads because they are so rare.
- There are more than fifty different kinds of kangaroos.

Many think that when cats inhale nepetalactone, it affects hormones that arouse sexual feelings, or at least alter their brain functioning to make them feel "high."
