Have you ever thought of getting in touch with your inner child from time to time? Obviously some people are willing to pay big money for the chance to do so in a proper environment．A Brooklyn-based adult preschool is charging customers between $333 and $999 for the chance to act like a kid again．

    At Preschool Mastermind in New York adults get to participate in show-and-tell，arts-and-crafts such as finger paint，games like musical chairs and even take naps．The month-long course also has class picture day where the adults are expected to have a field trip and a parent day．

    30-year-old Michelle Joni Lapidos，the brain behind the adult preschool，studied childhood education and has always wanted to be a preschool teacher．She's always on the lookout for new ways to get people in touch with the freedom of childhood．A friend encouraged her to start the mastermind course instead．

    According to Candice，her blogger friend，Preschool Mastermind gives adults a chance to relearn and master the things that they failed to understand as children．“I realized all the significances of what we learn in preschool，”said founder Michelle Joni，“People come here and get in touch with their inner child．It's magical．We are bringing ourselves back to another place，another time with ourselves when we are more believing in ourselves，more confident and ready to take on the world．”

    “One person's here because they want to learn not to be so serious．”Michelle said．“Another's here to learn to be more confident．”She explained that most of the classes were planned．However，Joni added that while the planned activities were fun，it was often the spontaneous(自发的)moments that attracted students．“It's the things you don't plan for，the sharing between friends and learning from each other．''

    Experience the newly opened Grand Canyon West Skywalk in Colorado.Departing from Grand Canyon's South Rim by Airplane to Grand Canyon's West Rim,you will land and take a ground tour to the Skywalk! Walk on air for 70 feet over the edge of Grand Canyon West.

    This Skywalk has been open since March 28,2007.Daily visitor-ship to the Skywalk has been over 4000 people. Please be patient to enjoy your moment on the Skywalk.

    After you have experienced the one and only Grand Canyon Skywalk Glass Bridge from where you can enjoy the scenery better,you will return to the Grand Canyon West airport and take your Airplane for a flight back to the South Rim of the Canyon.This is a tour never to be forgotten as you will have walked on air over the Grand Canyon.

    This is the incredible school where the headteacher's unique dedication to handwriting practice means EVERY pupil is ambidextrous.

Only ten percent of the population are left-handed, and only ONE percent can write with both hands. But all 300 students at Veena Vandini School in India can write with both their left and right hand, with some able to do both at the same time—in different languages.

    Every 45-minute lesson features 15 minutes devoted to handwriting practice, to make sure all students at the remote rural school have the skill.

    The school, which was founded in 1999, is located in a remote area, in Singrauli district, Madhya Pradesh. School founder and former solider Vp Sharma said he was inspired to demand the lessons by India's first president.

     “I read in a magazine that Dr Rajendra Prasad used to write with both hands. This inspired me to give it a try. Later, when I launched my school at my native village, I tried training the students.

     “We began training students from standard I and by the time they reach standard III, they were comfortable writing with both the hands. Students of standard VII and VIII can write with speed and accuracy. Further, they can write two scripts simultaneously, one with each hand.

     “Students also know several languages, including Urdu.”

    Mr Sharma said their unique dedication to handwriting led South Korean researchers to visit and study the pupils two years ago, to find out more about ambidexterity.

    Canada is a very large country. It is the second largest country in the world. By contrast it has a very small population. There are only about 29 million people there. Most Canadians are of British or French origin, and French is an official language of Canada as well as English. About 45% of the people are of British origin, that is, they or their parents or grandparents, etc., come from Britain. Nearly 30% are of French origin. Most of the French-Canadians live in the province of Quebec.

    Over the years, people have come to live in Canada from many countries in the world. They are from most European countries and also from China, besides other Asian countries.

    However, Canada was not an empty country when the Europeans began to arrive. Canadian Indians lived along the coast, by the rivers and lakes and in forests. Today there are only about 350, 000 Indians in the whole country, with their own languages. In the far north live the Inuit. There are only 27, 000 Canadian-Inuit. Their life is hard in such a difficult climate.

    There are two main things that make aircraft engineering difficult: the need to make every component as reliable as possible and the need to build everything as light as possible. The fact that an airplane is up in the air and can't stop if anything goes wrong, makes it perhaps a matter of life or death that its performance is completely dependable.

    Given a certain power of engine, and consequently a certain fuel consumption, there is a practical limit to the total weight of aircraft that can be made to fly. Out of that weight as much as possible is wanted for fuel, radio navigational instruments, passenger seats, or freight room, and of course, the passengers or freight themselves. So the structure of the aircraft has to be as small and light as safety and efficiency will allow. The designer must calculate the normal load that each part will bear. This specialist is called the "stress man." He takes notice of any unusual stress that may be put on the part as a precaution against errors in manufacture, accidental damage etc.

    The stress man's calculations go to the designer of the part, and he must make it as strong as the stress man says is necessary. One or two small parts are always tested to prove that they are as strong as the designer intended. Each separate part is tested, then a whole assembly—for example, a complete wing, and finally the whole aeroplane. When a new type of aeroplane is being made, normally only one of the first three made will be flown. Two will be destroyed on the ground in strict tests. The third one will be tested in the air.

    When a plane has passed all the tests it can get a government certificate of airworthiness, without which it is illegal to fly, except for test flying.

    Making the working parts reliable is as difficult as making the structure strong enough. The flying controls, the electronic equipment, the fire precautions, etc. must not only be light in weight, but must work both at high altitudes where the temperature may be below freezing point and in the hot air of an airfield in the tropics.

    To solve all these problems the aircraft industry has a large number of research workers, with elaborate laboratories and test houses, and new materials to give the best strength in relation to weight are constantly being tested.
