Pin money became an English phrase to describe extra cash set aside by wives to run the household at the turn of the twentieth century, When pins were rare enough to be sold on just two days of the year, January 1 and 2.

Although through time pins became more commonplace and far less expensive, the British courts still enforce any prenuptial agreement or property lien demanded by the wife as the “pin money charge.”

When did the first flowers bloom?

Mosses and fungi probably appeared about 400 million years ago. By about 200 million years ago, the earth sprouted sweeping forests of giant cycads, conifer trees, huge horsetails, and ferns. But the first flowering plants did not appear until the dinosaurs, sometime in the middle of the Cretaceous period, about 100 million years ago.

Before this, most of the trees had been gymnosperms, or plants with cones. Magnolias are among the oldest of all flowering plants, appearing about this time, along with orchids. With flowers came many insects, including butterflies, ants, termites, and bees. The flowering plants provided food for these insects, who spread the pollen from flower to flower to produce the seeds that would keep the flowers reproducing.

What is the Bill of Rights?

The Bill of Rights is made up of the first 10 amendments to the U.S. Constitution. The Bill of Rights guarantees rights and liberties to the American people. These amendments were proposed by Congress in 1789, and ratified (approved) by threefourths of the states on December 15, 1791, thereby officially becoming part of the Constitution.

The first eight amendments outline many individual rights guaranteed to all people of this nation, while the Ninth and Tenth Amendments are general rules of interpretation of the relationship among the people, the state governments, and the federal government.

Are soap, booger, and earwax really jellybean flavors?

Yes! And so are dirt, earthworm, vomit, and grass. It’s not really clear how the folks at the jelly belly company figured out the flavor recipe for each bean, but those that have tried them say they are authentic tasting! Jellybeans, a type of candy made from sugar, corn syrup, and food starch, have traditionally been made with fruit flavoring.

One company, called Jelly Belly, made flavors like butter popcorn, cotton candy, and watermelon in the 1980s. These jellybeans were endorsed by U.S. President Ronald Reagan, who kept a jar of them on his desk in the White House, and who also made them the first jelly beans in outer space, sending them on the 1983 Challenger shuttle as a surprise for the astronauts.

What’s a charley horse?

A charley horse a muscle cramp, or sudden, uncontrolled contraction of a muscle. This type of pain is generally felt in the legs, sometimes after heavy exercise, and usually lasts just a few minutes.

The expression probably came from the word “charley,” which is used to describe a horse that is lame.

What is head lice?

The head louse is a tiny, wingless insect that lives in human hairs and feeds on very small amounts of blood drawn from the scalp. Although they may sound kind of disgusting, lice appear often on young children in common settings, such as school. Lice aren’t dangerous and they don’t spread disease, but they are contagious and can be very annoying. Their bites may cause the scalp to become itchy and inflamed, and scratching may lead to skin irritation. They can be hard to get rid of, and take lots of work to make them go away and stay away.

Usually, using special medicated shampoos and thoroughly cleaning sheets, carpets, clothing, and personal products, like combs and brushes, gets rid of the pesky insects. Kids should try to avoid head-to-head contact at school (both in classrooms and on the playground) and while playing at home with other children. They also shouldn’t share combs, brushes, hats, scarves, bandanas, ribbons, barrettes, towels, helmets, or other personal care items with anyone else, whether they may have lice or not.

What are fossils?

A fossil is the hardened remains or an imprint of a plant or animal that lived a very long time ago. Some fossils are thousands of years old, others are several hundred million years old. Most plants and animals died and then decayed without ever leaving a trace. But some were buried under mud, rocks, ice, or other heavy coverings before decaying. The pressure of these layers over thousands of years turned animal and plant remains into rock.

Usually fossils preserve the organism’s hard parts: the bones or shells of an animal and the seeds, stems, and leaf veins of plants. Sometimes the fossil is the actual animal part, like a bone or tooth, that has hardened into rock. Some fossils, called trace fossils, show the imprint of parts of the animal or plant. Occasionally these imprints act as a mold, and the sediment that fills the imprint hardens and becomes a cast of, for example, a dinosaur footprint. Sometimes bones or trees are preserved by minerals that seep into the part’s pores and then harden, or petrify, that part. Arizona’s Petrified Forest contains numerous examples of giant trees that were petrified millions of years ago.

Why do we put candles on a birthday cake?

The Greeks borrowed celebrating birthdays from the Egyptian pharaohs and the cake idea from the Persians. Then early Christians did away with birthday parties for a while until the custom re-emerged with candles in Germany in the twelfth century.

Awakened with the arrival of a birthday cake topped with lighted candles, which were changed and kept lit until after the family meal, the honoured child would make a wish that, it was said, would come true only if the candles were blown out in a single breath.

How do robots like ASIMO and Mahru work?

Robots like ASIMO and Mahru are sophisticated, expensive, highly technologically advanced machines that are built upon major components found in humans. Robot technicians use the inner workings of the human body as the model for the robots that they make. This modeling ensures that their robots are as lifelike as possible. First, the robot technician designs the five major components he or she will put into the robot: a body structure, a muscle system, a sensory environment, a power source, and a brain system.

Next, they build an intricate machine made up of electrical circuits, electrical valves, piston cylinders, electric motors, solenoids, hydraulic systems, and more—each plays a specific role in getting the robot to work. Every robot has a computer that controls everything else within its body. Many robots can talk and some can even smell, taste, and hear. To get the body of a robot moving, the computer must “tell” the specific part to move. If the technician wants the robot to do something new once it has been made, he or she writes a new computer program. In some cases, if the task is too big for the robot’s wiring system, new parts need to be installed. NUMBERS AND COUNTING

What is school like in other countries?

Schools are different in every country in the world. A school may have lots of classrooms, books, play equipment, and a playground, or lessons may take place under trees or in an open outdoor space. A temple, a tent, or a building on stilts may serve as a classroom for some children. In poor places that have no money to build schools, children may learn their lessons outdoors. In isolated places—such as the Australian outback or the Alaskan wilderness—where families live hundreds of miles apart and far from cities or towns, children may get their lessons from teachers over two-way radios or the Internet. All around the world, schools are a reflection of the culture in which they are formed.

In Japan, as students enter school, they remove their shoes and put on slippers, a Japanese custom. They do not write with pencils; instead, each child has his or her own ink well, brush, and ink for writing the kanji (Japanese characters). Children often clean their classrooms (including dusting cubbies and mopping floors), and at the end of each class the students thank their teacher and bow. In schools in Brazil and other South American countries, children often go to school barefoot. In India, children practice yoga in school. And many children that go to public schools in European countries, such as Germany and France, ride their bikes to school or take public transportation, rather than school buses.
