Acoustic levitation allows small objects, like droplets of liquid, to float. Unless you travel into the vacuum of space, sound is all around you every day. But most of the time, you probably don't think of it as a physical presence. You hear sounds; you don't touch them. The only exceptions may be loud nightclubs, cars with window-rattling speakers and ultrasound machines that pulverize kidney stones. But even then, you most likely don't think of what you feel as sound itself, but as the vibrations that sound creates in other objects. The idea that something so intangible can lift objects can seem unbelievable, but it's a real phenomenon. Acoustic levitation takes advantage of the properties of sound to cause solids, liquids and heavy gases to float. The process can take place in normal or reduced gravity. In other words, sound can levitate objects on Earth or in gas-filled enclosures in space.
Kids can dream up some pretty awesome jobs, but can they keep the dream alive when they grow up? If you've ever asked a 5-year-old what she wants to be when she grows up, you'll probably recognize a theme. Astronaut, dancer, poet, princess, unicorn trainer - whatever the answer, it usually sounds like a lot of fun. Fifteen or 20 years later, that sense of fun will likely be trumped by a sense of financial responsibility. It's almost a rite of passage to give up the idea that a grown-up job can be fun. But fun and money aren't necessarily mutually exclusive. To be sure, even in the entertainment industry, Fallon is an anomaly. The jobs in which workers claim to be happiest are far less glamorous, but most pay a decent wage. There are also plenty of jobs that pay next to nothing and are a real drag. And even jobs that once seemed like a lot of fun, once you're in them long enough, can start to feel like work.
In 1763, a British army general ordered that blankets used on smallpox patients be sent to American Indian tribes. British Revolutionary War troops would also infect themselves with traces of smallpox, rendering themselves immune, in hopes of passing the disease along to the enemy. During World War I, Germans infected livestock headed for the Allies with anthrax. Even though the attack proved to be unsuccessful, it led to the creation of the Geneva Protocol in 1925. This prohibited the use of biological and chemical agents during wartime, while allowing research and development of these agents to continue. The British and German armies may have dabbled in biological warfare, but the Japanese went full steam ahead in the years that preceded World War II. Hundreds of thousands of Chinese civilians were killed by biological means at the hands of the Japanese army. One of these attacks included dropping paper bags containing plague-infested fleas from low-flying airplanes.
Enthusiasts hold annual PEZ conventions, avidly read publications like PEZ Collectors News, and eagerly bid for prized and/or rare PEZ figurines in Web auctions. In this article, we'll look at the nuances and allure of PEZ collecting, and tell you more about the PEZ museum. But first, let's take a look at the history and development of PEZ. He first became successful in the family grocery business by peddling a new brand of baking powder that made cakes lighter. But in the mid-1920s, young Haas had an inspiration of his own. He bought peppermint oil from a chemist and used it to create tiny, sugar-based candies that he shaped like bricks to make them easier for a machine to wrap. The candy's name, PEZ, was an abbreviation of "Ppferrerminze," the German word for peppermint. Haas' new candy caught on in Vienna, and after World War II, the inventor looked for ways to broaden his market.
