What makes apples "rust"?
Apples and other produce (e.g., pears, bananas, peaches, potatoes) contain an enzyme called polyphenol oxidase or tyrosinase that reacts with oxygen in the air and iron-containing phenols that are also found in the apple. The oxidation reaction basically forms a sort of rust on the surface of the fruit. Rusty apple! Yuck!
Why does a "head" of foam form on beer?"
The 'head' on a freshly-pulled pint is due to the gas that is released from the beer as it is drawn from the barrel. This gas is carbon dioxide, which forms tiny bubbles in the beer. These bubbles float to the top of the glass and make a froth. But as the bubbles gradually burst, the froth collapses.
The "foam" lattice itself consists of dissolved barley protein, and is easily destabilized by fats and oils, such as those found in potato chips, peanuts, and even lipstick, making the beer go "flat". The lesson? Refrain from kissing and beer drinking, or beer drinking and kissing, whichever applies.
Who invented toilet paper?
The first factory-made paper marketed exclusively for toilet use was produced by Joseph Cayetty in the United States in 1857. Cayetty's name was printed on every sheet.
Before this invention, wealthy people used wool, lace or hemp for their ablutions, while less wealthy people used their hand, defecated into rivers, or cleaned themselves with various materials such as rags, wood shavings, leaves, grass, hay, stone, sand, moss, water, snow, maize husks, or seashells, depending upon the country and weather conditions or social customs.
In some parts of the world, the use of newspaper, or telephone directory pages were common. Old Farmer's Almanac was sold with a hole punched in the corner so it could be hung on a nail in the outhouse. The widely-distributed Sears catalog was also a popular choice until it began to be printed on glossy paper (at which point some people wrote to the company to complain). Sears catalog? Who would have thunk it?!
Why do dogs chase their own tails?
Chasing moving objects is a sure way of fine-tuning predatory skills. Ball chasing, stick chasing, and leaf chasing, are all ways in which this play form is expressed. If deprived of play predatory opportunities, dogs may resort to vacuum chasing of imaginary creatures, may pace, circle, or chase their own tails. So tail chasing in just another repressed manifestation of your pets predatory nature. No wonder cropped tailed dog breeds like Bulldogs and Rottweilers are so angry all the time.
How long does the money in your pocket last before it is replaced?
That depends on the denomination of the note. A $1 bill lasts 18 months; $5 bill, two years; $10 bill, three years; $20 bill, four years; and $50 and $100 bills, nine years. Bills that get worn out from everyday use are taken out of circulation and replaced.
The Bureau of Engraving and Printing produces 38 million notes a day with a face value of approximately $541 million. That doesn't mean there is $541 million more money circulating today than there was yesterday, though, because 95% of the notes printed each year are used to replace notes already in circulation. In other words, longevity of any piece of<
