A wrecking ball is a heavy steel ball, usually hung from a crane, that is used for demolishing large buildings. It was most common 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.

With the invention of hydraulic excavators and other machinery, the wrecking ball has become less common at demolition sites because its working efficiency is smaller compared to that of long reach excavators. Although the wrecking ball is still the most efficient way to raze a concrete frame structure, it is decreasing in use.

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.

Wrecking balls range from about 1,000 lb to around 12,000 lb (450 kg to 5400 kg). The ball is made from forged steel, which means the steel is not cast into a mold in a molten state. It is formed under very high pressure while the steel is red hot (soft but not molten) to compress and to strengthen it.

Bruce Frederick Joseph Springsteen (born September 23, 1949), nicknamed "The Boss," is an American singer-songwriter-performer who records and tours with the E Street Band. Springsteen is widely known for his brand of heartland rock, poetic lyrics, and Americana sentiments centered on his native New Jersey.

Springsteen's recordings have included both commercially accessible rock albums and more somber folk-oriented works. His most successful studio albums, Born in the U.S.A. and Born to Run, showcase a talent for finding grandeur in the struggles of daily American life; he has sold more than 65 million albums in the United States and more than 120 million worldwide and he has earned numerous awards for his work, including 21 Grammy Awards, two Golden Globes and an Academy Award. He is widely regarded by many as one of the most influential songwriters of the 20th century, and in 2004, Rolling Stone ranked him as the 23rd Greatest Artist of all time.

Springsteen was born in Long Branch, New Jersey, and spent his childhood and high school years in Freehold Borough. He lived on South Street in Freehold Borough and attended Freehold Borough High School. His father, Douglas Frederick Springsteen, was of Dutch and Irish ancestry and worked, among other vocations, as a bus driver, although he was frequently unemployed; his surname is Dutch for jump stone. His mother, Adele Ann (née Zerilli), was a legal secretary and was of Italian ancestry. His maternal grandfather was born in Vico Equense, a city near Naples. He has two younger sisters, Virginia and Pamela. Pamela had a brief film career, but left acting to pursue still photography full time; she took photos for the Human Touch and Lucky Town albums.
