Underground garden: People living in London, England, during World War II were well aware of the city's need for underground bunkers where people could escape air raids. Today, one of these bunkers has found a new purpose. It has become a subterranean farm known as Growing Underground. Located 33 metres under Clapham High Street in the southwest part of London, the concept was the brainchild of co-founder Richard Ballard. The underground garden has no natural light, of course, so LED lights provide nourishment for the hydroponically grown plants, which include radishes, pea shoots, fennel, coriander, and more.
Hiding place: A car thief from the province of Alberta, Canada, didn't cover up his tracks very well, and that led to his capture. Police received word that a Jeep had been stolen from the town of Olds, about 89 kilometres north of Calgary. Someone also reported a vehicle in a ditch on a nearby rural road, which turned out to be the Jeep. Upon taking a closer look, police found a pretty clear clue about where the thief had gone footprints in the snow. The officers followed by foot, and soon discovered, under a pile of hay in a barn, a young man whom they charged with the offense.
The black violin: Violinists all over the world appreciate the sound of a Stradivarius violin, made by Antonio Stradivari in the 17th and 18th centuries. A replica of one of these instruments, made in 1992 and named Blackbird (after the common bird), was created by Swedish sculptor Lars Widenfalk. The artist made the creation out of a piece of diabase, a dark-colored, igneous rock. While using his chiseling tools, he had noticed the lovely sound the stone made, and decided to try making an instrument. Widenfalk used black ebony for a few pieces, such as the fingerboard and chin rest. Many musicians have played Blackbird over the years.
Keeping time: Budapest, Hungary, is home to a unique installment called the Timewheel, which was unveiled in 2004 to honor the country's entrance into the European Union. The Timewheel is an enormous hourglass in which small pieces of glass, rather than sand, trickle from the top v-shaped reservoir to the bottom one. A computerized system assists with the release of the glass, which takes an entire year to drop from top to bottom. Every year on December 31, the Timewheel must be manually rotated 180 degrees, with the help of a four-person team using steel cables. Then the glass begins keeping time for the next year.
