You can watch the following animation to learn more about the basics of sound. Click the arrow to move on to the next slide. Acoustic levitation uses sound traveling through a fluid -- usually a gas -- to balance the force of gravity. On Earth, this can cause objects and materials to hover unsupported in the air. In space, it can hold objects steady so they don't move or drift. The process relies on of the properties of sound waves, especially intense sound waves. We'll look at how sound waves become capable of lifting objects in the next section. A basic acoustic levitator has two main parts -- a transducer, which is a vibrating surface that makes sound, and a reflector. Often, the transducer and reflector have concave surfaces to help focus the sound. A sound wave travels away from the transducer. Bounces off the reflector. Three basic properties of this traveling, reflecting wave help it to suspend objects in midair.|This material may not be published, broadcast, rewritten, or redistributed. 2022 FOX News Network, LLC.

Fox News contributor Karl Rove joins 'Hannity' to discuss the state of the runoffs. Warnock, a Senate candidate in Georgia's Jan. 5 runoffs, said in what appears to be a roundtable discussion. Those comments came as part of a broader talk on Black theology in the U.S. Warnock's campaign did not immediately respond to Fox News' request for comment. The video clip, which was posted to YouTube by The Black Church Center for Justice and Equality in 2014, touched on a longstanding issue that continued to hang over Warnock's campaign. Electronic cigarettes closely resemble the real thing. You're at your favorite restaurant, enjoying a meal. A diner at the next table is puffing on a cigarette, letting out a cloud of smoke. Because smoking isn't allowed in the restaurant, you're thinking about asking the smoker to put the cigarette out. But before you protest, consider this: Your neighbor may not be smoking at all. Electronic cigarettes, also known as smokeless cigarettes, e-cigarettes, or e-cigs, are an alternative method of consuming nicotine, the addictive chemical found in tobacco. Manufacturers often design e-cigarettes to look like regular cigarettes, but they contain no tobacco and don't require a match -- or any flame at all. There's no fire, no ash and no smoky smell. E-cigarettes do not contain all of the harmful chemicals associated with smoking tobacco cigarettes, such as carbon monoxide and tar. Manufacturers and satisfied customers say the e-cigarette is a healthier alternative to tobacco cigarettes, which cause millions of deaths every year.|Kyiv shines out as a historic town, which has witnessed many periods throughout the history.
