Wrecking ball

A wrecking ball is a heavy steel ball, usually hung from a crane, that is used for demolishing large buildings. It was most commonly in use during the 1950s and 1960s. Several wrecking companies claim to have invented the wrecking ball. An early documented use was in the breaking up of the SS Great Eastern in 1888-1889, by Henry Bath and Co, at Rock Ferry on the River Mersey.

In 1999, the wrecking ball was described as "one of the most common forms of large-scale coarse demolition." Although the wrecking ball is still the most efficient way to raze a concrete frame structure, its use is decreasing. With the invention of hydraulic excavators and other machinery, the wrecking ball has become less common at demolition sites as its working efficiency is less than that of high reach excavators.

Construction and design

Modern wrecking balls have had a slight re-shaping, with the metal sphere changed into a pear shape with a portion of the top cut off. This shape allows the ball to be more easily pulled back through a roof or concrete slab after it has broken through.

Miley Cyrus

Miley Ray Cyrus (born Destiny Hope Cyrus; November 23, 1992) is an American singer, songwriter, and actress. Born and raised in Franklin, Tennessee, she held minor roles in the television series Doc and the film Big Fish in her childhood. Cyrus became a teen idol for her portrayal of the starring character Miley Stewart in the Disney Channel television series Hannah Montana in 2006; her father Billy Ray Cyrus additionally starred in the show. Cyrus subsequently signed a recording contract with Hollywood Records; her debut studio album Meet Miley Cyrus (2007) was certified quadruple-platinum by the Recording Industry Association of America (RIAA) for exceeding four million shipments. Cyrus released her second album Breakout and launched her film career as a voice actress in the animated film Bolt in 2008.

Cyrus starred in the feature film Hannah Montana: The Movie and began cultivating a maturing image with her EP The Time of Our Lives in 2009. In 2010, she released her third album Can't Be Tamed, which stands as the lowest-selling record of her career, and starred in the coming-of-age film The Last Song. During production of the movie, she began an on-again, off-again relationship with her co-star Liam Hemsworth. Cyrus focused on her acting career with several television and film appearances in 2011 and 2012. Her sexually explicit behavior generated widespread controversy while promoting her fourth album Bangerz (2013), her first under her recording contract with RCA Records. Cyrus' independently-released fifth studio album Miley Cyrus & Her Dead Petz (2015) deviated from her traditional pop style for more psychedelic experimentation.

Chief Keef

Keith Cozart (born August 15, 1995), better known by his stage name Chief Keef, is an American rapper and record producer from Chicago, Illinois. Growing up in Chicago's Englewood neighborhood, Keef began rapping at an early age, and used his mother's karaoke machine and blank tapes to record his music. During his teenage years and while under house arrest, Keef's music videos were met with acclaim from local high school students. His increasing popularity led to him being the subject of a brief bidding war among labels. Ultimately, Keef signed a major record deal with Interscope Records and later signed with 1017 Brick Squad. Keef also became the CEO of his own record label, Glory Boyz Entertainment, which later developed into Glo Gang. His debut album Finally Rich was released on December 18, 2012.

Since becoming famous, Keef has continued to experience ongoing legal issues. These legal issues, accompanied with Keef's notability within Chicago's drill music genre, have caused Keef to gain a gangster-like image, which has been compared with past gangsta rappers, such as 50 Cent. Despite being dropped from Interscope in late 2014, Keef continued self-releasing mixtapes through his Glo Gang label. Although Keef had originally planned Bang 3 to be released as his second album, a then-track from the album, "Nobody", developed into its own project. Keef released Nobody as a full-length album in December 2014, while continuing to delay the often-pushed back Bang 3.

Ball

A ball is a round, usually spherical but sometimes ovoid, object with various uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. In the context of sports, "ball" need not refer to a spherical object, as is the case in American football. Balls can also be used for simpler activities, such as catch, marbles and juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles.

Although many types of balls are today made from rubber, this form was unknown outside the Americas until after the voyages of Columbus. The Spanish were the first Europeans to see bouncing rubber balls (albeit solid and not inflated) which were employed most notably in the Mesoamerican ballgame. Balls used in various sports in other parts of the world prior to Columbus were made from other materials such as animal bladders or skins, stuffed with various materials.
