Guinness World Records has long been recording some of the most amazing and astonishing travel and tourism facts. Here we are sharing some of the most unbelievable record-breaking accounts, all fully fact-checked and Guinness-approved.

Largest Ice Structure—The Ice Hotel in Sweden

    Each year, the ice hotel in Jukkasjarvi, Sweden, is rebuilt from blocks of frozen ice from the nearby River Torne. Covering an area of 5,500 square metres, the hotel is unsurprisingly open seasonally, from December to March, when it melts away. In 2015, the hotel celebrated its 25^th anniversary, complete with an ice bar, an ice church and ice bedrooms—one even featured a London Tube carriage made entirely of ice.

Tallest Waterfall—Angel Falls, Venezuela

    The largest waterfall by vertical(垂直的) area may be Victoria Falls, which sit on the border between Zimbabwe and Zambia, but it's South America that's home to the world's tallest.

    Angel Falls, located in Bolivar, Venezuela, has an impressive, uninterrupted drop of 807 metres.

    It was actually named after the American pilot, Jimmie Angel, who first recorded it in his logbook on November 16, 1933.

Largest Area of Glowing Sea—Indian Ocean, near Somalia

    Bioluminescence(生物体发光) is the production and emission of light by a living thing and can be used to explain the surprising phenomenon(现象)of “glowing oceans.”

    It was in 1995 that scientists detected glowing sea in the Indian Ocean—just off the coast of Somalia-via satellite, The water was more than 250 kilometres long, and it was all thanks to the bacteria called phytoplankton.

Most Expensive Hotel Room—The Royal Penthouse Suite at Geneva's Hotel President Wilsom

    This particular suite is just the ticket, costing as much as US$83,000(£53,760)per night.

    But the high price will gain you access to 12 bedrooms and 12 marble bathrooms across 18,000 square feet.

    Mark felt that it was time for him to take part in his community, so he went to the neighborhood meeting after work. The area city council (委员会) woman was leading a discussion about how the quality of life was decreasing. The neighborhood faced many problems. Mark looked at the charts taped to the walls. There were charts for parking problems, crime, and for problems in vacant buildings. Mark read from the charts, “Police patrols(巡逻) cut back, illegal parking up 20%”. People were supposed to suggest solutions to the councilwoman. It was too much for Mark. "The problems are too big," he thought. He turned to the man next to him and said, "I think this is a waste of my time. Nothing I could do would make a difference here."

    As he neared the bus stop on his way home, Mark saw a woman carrying a grocery bag and a baby. As Mark got closer, her other child, a little boy, suddenly dashed into the street. The woman tried to reach for him, but as she moved, her bag shifted (滑落), and groceries started to fall out. Mark ran to take the boy's arm and led him back to his mother. Then he picked up the groceries while the woman smiled in relief. "Thanks!" she said. "You've got great timing!" "Just being neighborly," Mark said. As he rode home, he glanced at the walls of the bus. On one of them was “Small acts of kindness add up.”, Mark smiled and thought, "Maybe that's a good place to start."

    Danielle Steel, America's sweetheart, is one of the hardest working women in the book business. Unlike other productive authors who write one book at a time, she can work on up to five. Her research before writing takes at least three years. Once she has fully studied her subjects, ready to dive into the book, she can spend twenty hours nonstop at her desk.

    Danielle Steel comes from New York and was sent to France for her education. After graduation, she worked in the public relations and advertising industries. Later she started a job as a writer which she was best fit for. Her achievements are unbelievable: 390 million copies of books in print, nearly fifty New York Times best-selling novels, and a series of "Max and Martha" picture books for children to help them deal with the real-life problems of death, new babies and new schools. Her 1998 book about the death of her work shot to the top of the New York Times best-selling list as soon as it came out. Twenty-eight of her books had been made into films. She is listed in the Guinness Book of World Records for one of her books being the Times best-seller for 381 weeks straight.

    Not satisfied with a big house, a loving family, and a view of the Golden GateBridge, Danielle Steel considers her readers to be the most important resource and has kept in touch with them by e-mail. While she is often compared to the heroines of her own invention, her life is undoubtedly much quieter. But, if she does have anything in common with them, it is her strength of will and her inimitable (独特的) style. There is only one Danielle Steel.

    We all love bank holidays. In the UK, we only get eight bank holidays in one year, and at least five of those occur around Christmas time and Easter time! A bank holiday is a British English term. This is an official day that is decided by the government, when banks, shops and offices close for the day even though it's a weekday—usually a Monday, and a lot of people have a day off work.

    Bank holidays are different in Colombia—firstly, they are called “festivos”. There are twenty festivos for the whole country in one year! In Britain ，people get more holiday allowance(津贴)than Colombians but fewer bank holidays. There can be even more festivos in Colombia, depending on which region of Colombia you live in. This is because different regions have their own holidays. For example, some regions have a patron saint(守护神) in their region, so they have an extra festivo to celebrate that saint.

    However, there are some days that are national holidays for historical reasons. There is an Independence Day celebration on July 20 every year. This is just like Bastille Day in France on July 14, or Independence Day in the United States on July 4. Other important festivos in Colombia are :Labour Day, on May 1, and Columbus Day on October 12. Columbus Day is a historical bank holiday that almost every county on the continent of America celebrates. This includes Colombia, Chile, Peru, Argentina, Mexico and the United States. It is a memorialization of the day that the Italian sailor, Christopher Columbus, first reached land on the continent in the year 1492. Many people criticize this day and say it is not something to celebrate because of the way Columbus and his teams treated the people that were already living there.

    Mirroring China's Past: Emperors and Their Bronzes

    Chinese bronzes (青铜) of the second and first millennia BC are some of the most distinctive achievements in the history of art. These vessels (容器) were made to carry sacrificial offerings, to use in burial or to honor noble families in public ceremonies. When they were found by emperors centuries later, these spiritually significant objects were seen as signs of heavenly messages about a ruler or a dynasty and became prized items in royal collections. This exhibition —the first to explore these ancient objects throughout Chinese history — presents a rare opportunity to experience a large number of these works together in the United States.

    Unlike Greek and Roman bronze sculptures of human and animal forms, most objects from Bronze Age China (about 2000 - 221 BC) were vessels for ceremonial use. Beginning with the Song dynasty (960 - 1279), emperors unearthed these symbolic works and began collecting them, considering them to be evidence of their own authority as rulers. In addition to impressive collections, the royal fascination with bronzes led to the creation of numerous reproductions and the comprehensive cataloguing of palace holdings. These catalogues are works of art themselves, featuring beautiful drawings and detailed descriptions of each object.

    From the 12th century onward, scholars and artists also engaged in collecting and understanding ancient bronzes. Unlike emperors, scholars regarded bronzes as material evidence of their efforts to recover and reconstruct the past, and they occasionally exchanged them as tokens (象征) of friendship. Today ancient bronzes still occupy a primary position in Chinese culture — as historical objects and as signifiers of an important cultural heritage that inspires new generations, as seen in the works of contemporary artists on view in this presentation.

    Mirroring China's Past brings together approximately 180 works from the An Institute of Chicago's strong holdings and from the Palace Museum in Beijing, the Shanghai Museum, and important museums and private collections in the United States. By providing viewers with a new understanding of ancient bronzes and their significance through time, the exhibition demonstrates China's fascinating history and its developing present.

    Does stress cause gray hair? Many people believe that tension and stress can cause your hair to lose its color. In fact, it is an old-wives' tale that being upset all the time can result in premature graying. Here is a closer look at this situation and why some believe that this old wives' tale could be true.

    As one ages, the hairs on the head also age. In fact, just about everything on the human body begins to show signs of wear and tear (磨损) after a while. The joints wear and become stiff and skin wears and becomes wrinkled. Hairs on the head grow and eventually die. They are replaced, but in the process something else happens.

    When new hairs are replacing the old ones, the color or pigment (色素) is also added to them. However, as one ages, this pigment becomes less and less available. At first, hairs will have a limited amount of pigment and they will appear to be grayish in color. In time, they will lose all of their pigment and will be white. Many things are known to cause graying, and genetics is a very powerful factor. If one of your parents turns gray at an early age, there is a good chance that you will too. Some people begin the graying process in high school, while others may be over the age of forty.

    Constant worry and tension can have many harmful effects on the human body. It is a known fact that stressful times can cause one to suffer hair loss. It would make sense that if it can cause these problems, perhaps it also may contribute to graying. However, there is no sound evidence to support this.

    On the other hand, many medical professionals believe that there may be a link between graying and a constant state of anxiety or tension. Does stress cause gray hair? There is no scientific evidence to support the theory, but it is best to avoid stressful situations.
