Cameron Jibril Thomaz (born September 8, 1987), better known by the stage name Wiz Khalifa, is an American rapper. He released his debut album, Show and Prove, in 2006, and signed to Warner Bros. Records in 2007. His Eurodance-influenced single, "Say Yeah", received urban radio airplay, charting on the Rhythmic Top 40 and Hot Rap Tracks charts in 2008. Khalifa parted with Warner Bros. and released his second album, Deal or No Deal, in November 2009. He released the mixtape Kush and Orange Juice as a free download in April 2010; he then signed with Atlantic Records. He is also well known for his debut single for Atlantic, "Black and Yellow", which peaked at number 1 on the Billboard Hot 100. His debut album for the label, Rolling Papers, was released on March 29, 2011.

Khalifa was born on September 8, 1987 to a mother and a father serving in the military. His parents divorced when Khalifa was about three years old. His parents' military service caused him to move regularly: Khalifa lived in Germany, the United Kingdom, and Japan before settling in Pittsburgh where he attended Taylor Allderdice High School.

Antoine Carraby (born December 11, 1967), better known by his stage name DJ Yella, is an American DJ, music producer, film director and pornographer from Compton, California. He was a member of the World Class Wreckin' Cru along with Dr. Dre. He later became a founding member of the pioneering gangsta rap group N.W.A (composed of Yella, Dr. Dre, Ice Cube, MC Ren, and Eazy-E). Along with Dre, he produced Eazy-E's debut album Eazy-Duz-It and all three N.W.A albums, translating into millions of sales. He co-produced the platinum-selling debut albums of J.J. Fad and Michel'le with Dre and contributed to The D.O.C.'s 1989 album No One Can Do It Better (also produced by Dre). Jerry Heller witnessed Dre and Yella's work together and wrote in 2006 of an almost eerie understanding between the pair, as they crafted high quality beats and productions with almost no words or full sentences needing to be spoken.^{[citation needed]}

Yella remained close to Eazy and stayed on production duties at Ruthless Records after the acrimonious break up of N.W.A. He produced J.J. Fad's second album Not Just a Fad (1990), Yomo & Maulkie's album Are U Xperienced? (1991), two tracks from Eazy-E's It's On (Dr. Dre) 187^um Killa (1993), the gold-selling hit single Foe tha Love of $ from Bone Thugs-N-Harmony's Creepin on ah Come Up E.P., Menajahtwa's album Cha-licious, and tracks from H.W.A.'s Az Much Ass Azz U Want E.P. (all three from 1994), and oversaw Eazy's final album in 1995 after his sudden AIDS-related death.

Ice cubes are small, roughly cube-shaped pieces of ice, conventionally used to cool beverages. Ice cubes are sometimes preferred over crushed ice because they melt more slowly; they are standard in mixed drinks that call for ice, in which case the drink is said to be "on the rocks."

Ice cubes that are crushed or sheared into irregularly-shaped flakes may add an interesting aesthetic effect to some cocktails. Crushed ice is also used when faster cooling is desired, since the rate of cooling is governed by the number and average radius of the ice particles.

Melting ice cubes sometimes precipitate white flakes, commonly known as "floaties". This is calcium carbonate which is present in many water supplies and is completely harmless.^{[citation needed]}

American physician and humanitarian John Gorrie built a refrigerator in 1844 with the purpose of cooling air. His refrigerator produced ice which he hung from the ceiling in a basin. Gorrie can be considered the creator of ice cubes, but his aim was not to cool drinks: he used the ice to lower the ambient room temperature. During his time, a dominant idea was that bad air quality caused disease. Therefore, in order to help treat sickness, he pushed for the draining of swamps and the cooling of sickrooms.
