A penny for your thoughts? If it's a 1943 copper penny, it could be worth as much as fifty thousand dollars. In 1943, most pennies were made out of steel since copper was needed for World War II, so the 1943 copper penny is ultra-rare. Another rarity is the 1955 double die penny. These pennies were mistakenly double stamped, so they have overlapping dates and letters. If it's uncirculated, it'd easily fetch $25,000 at an auction. Now that's a pretty penny.

Before you put on that skeleton costume and rove door-to-door pandering for candy, take a minute to reflect on this tradition. Halloween is believed to have come from an ancient Celtic festival dating back some 2,000 years. November 1st was the Celtic New Year and marked the end of summer to the Celts. They celebrated on its eve by wearing costumes made of animal skins and dancing around bon fires. Over the next two millennia, this primitive celebration grew to be the candy fueled costume ball that we know today.

When one hears the term "reality" applied to a show, one might expect that the events portrayed occurred naturally or, at the least, were not scripted. This is not always the case. Many reality shows occur in unreal environments, like rented mansions occupied by film crews. Such living environments do not reflect what most people understand to be "reality." Worse, there have been accusations that events not captured on film were later restaged by producers. Worse still, some involved in the production of "reality" television claim that the participants were urged to act out story lines premeditated by producers. With such accusations floating around, it's no wonder many people take reality TV to be about as real as the sitcom.

It is estimated that over twenty million pounds of candy corn are sold in the US each year. Brach's, the top manufacturer, sells enough candy corn to circle the earth 4.25 times if each piece were laid end to end. That's a lot of candy corn, but that's nothing compared to the production of Tootsie Rolls. Over 64 million Tootsie Rolls are produced every day! But even Tootsie Rolls have got nothing on the candy industry's staple product: chocolate. Confectioners manufacture over twenty billion pounds of chocolate in the United States each year. Now that's a mouthful!

Screech! When a driver pushes on the brake pedal, it initiates a process that causes the vehicle to stop in motion. We literally trust braking systems with our lives every time we get into a vehicle or cross at a busy intersection. How does this life-critical process work? It begins when the pedal is pushed. At this moment brake fluid is released into the braking mechanisms. As the fluid collects, this creates a leverage, which causes a friction to be applied. This friction will create a force that will cause the wheels to stop and allow you to reach your destination safely. Beep! Beep!

There are many types of lethal venom in the animal kingdom, but perhaps no stranger carrier than the platypus. The platypus is one of few venomous mammals. Male platypus carry a venom cocktail in their ankle spurs. This venom incapacitates victims with excruciating pain. Stranger still, the platypus is the only mammal that uses electroreception. That means that the platypus uses its bill to sense the electricity produced by the muscular movements of its prey. Electroreception is a sixth sense different from seeing, hearing, smelling, tasting, or feeling. Perhaps most odd, the platypus is the only mammal that lays eggs rather than giving birth to live young. What an odd creature indeed.

Yellowstone National Park is mainly located in Wyoming, although three percent is located in the state of Montana. The Continental Divide of North America runs diagonally through the southwestern part of the park. The park sits on the Yellowstone Plateau, which is an average elevation of 8,000 feet above sea level. This plateau is bounded on nearly all sides by mountain ranges. There are 290 waterfalls that are at least fifteen feet in the park, the highest being the Lower Falls of the Yellowstone River, which falls 308 feet.

The term "amnesia" refers to complete or partial memory loss. Almost all of us will experience some form of amnesia in our lives, even if it's just a simple case of verbal amnesia, like forgetting someone's name. Fortunately, there are things that you can do to prevent amnesia. Here is a list of foods that you can eat to improve your memory: almonds, walnuts, bananas, honey, apples, and black pepper. Though these foods may not reverse post-traumatic amnesia, they should improve your memory in daily life if you eat them regularly enough.

Today's economy is tough, but there are a lot of ways that you can cut back. Instead of paying big bucks to some fancy mechanic, you can change your own oil. First, put on some clothes and safety gear. Once you are properly dressed, crawl under your car and remove the oil plug. Drain the oil into an oil pan. Wait a few minutes to make sure that the old oil has drained completely, and then replace the oil plug. Remove the oil filter. Replace it with a new one and pour four or five fresh quarts of oil into your car's engine. Wasn't that easy?

Ansel Bourne was a preacher, carpenter, and most likely an inspiration for the name "Bourne" in the movie and novel series, "The Bourne Identity." Up until 1857, Bourne had been a carpenter, until he was called to religion. After 1858, he worked as a evangelical preacher, until 1887. He set up shop in Norristown, Pennsylvania, as a candy maker using the name A.J. Brown. Three months later, he woke up not knowing where he was, with no memory of the previous months. The case of Mr. Bourne has fascinated psychologists, and some film makers, for years.
