Yo-yo
A yo-yo (also spelled yoyo) is a toy which in its simplest form is an object consisting of an axle connected to two disks, and a length of string looped around the axle, similar to a slender spool. It is played by holding the free end of the string known as the handle (usually by inserting one finger in a slip knot) allowing gravity or the force of a throw to spin the yo-yo and unwind the string (similar to how a pullstring works), then allowing the yo-yo to wind itself back to one's hand, exploiting its spin (and the associated rotational energy). This is often called "yo-yoing". First made popular in the 1920s, yo-yoing remains a popular pastime of many generations and cultures. It was first invented in ancient Greece.
In the simplest play, the string is intended to be wound on the spool by hand; The yo-yo is thrown downwards, hits the end of the string, then winds up the string toward the hand, and finally the yo-yo is grabbed, ready to be thrown again. One of the most basic tricks is called the sleeper, where the yo-yo spins at the end of the string for a noticeable amount of time before returning to the hand.
YOYO-1
YOYO-1 is a green fluorescent dye used in DNA staining. It belongs to the family of monomethine cyanine dyes and is a tetracationic homodimer of Oxazole Yellow (abbreviated YO, hence the name YOYO), typically available as tetraiodide salt. In aqueous buffer, free YOYO-1 dye (absorption: λmax 458 nm, emission: λmax 564 nm) has very low fluorescence quantum yield, however the intensity of fluorescence increases 3200 times upon binding to double-stranded DNA (absorption: λmax 489 nm, emission: λmax 509 nm).
Synthesis
YOYO-1 is prepared by alkylation of N,N,N’,N’-tetramethyl-1,3-propanediamine with 2 equivalents of N-(3-iodopropyl) analogue of Oxazole Yellow, which is available in three steps from 2-mercaptobenzoxazole:

Martini (cocktail)
The Martini is a cocktail made with gin and vermouth, and garnished with an olive or a lemon twist. Over the years, the Martini has become one of the best-known mixed alcoholic beverages. H. L. Mencken called the Martini "the only American invention as perfect as the sonnet" and E. B. White called it "the elixir of quietude".
Preparation
By 1922 the Martini reached its most recognizable form in which London dry gin and dry vermouth are combined at a ratio of 2:1, stirred in a mixing glass with ice cubes, with the optional addition of orange or aromatic bitters, then strained into a chilled cocktail glass. Over time the generally expected garnish became the drinker's choice of a green olive or a twist of lemon peel.
A dry Martini is made with dry, white vermouth. By the Roaring Twenties, it became common to ask for them. Over the course of the century, the amount of vermouth steadily dropped. During the 1930s the ratio was 3:1, and during the 1940s the ratio was 4:1. During the latter part of the 20th century, 6:1, 8:1, 12:1, or even 50:1 or 100:1 Martinis became considered the norm.
Martini (quartet)
Martini is the barbershop quartet that won the Sweet Adelines International Quartet Championship for 2012 on October 21, 2011, in Houston, Texas. SAI, "one of the world's largest singing organizations for women", has members over five continents who belong to more than 1200 quartets.
History
Martini formed in July 2007 at Sandy Marron's home in Tacoma, Washington. Singers Sandy Marron (tenor), Lisa Myers (lead), Shannon Harris (bass) and DeAnne Haugen (bari) were the "original blend" of voices. In April 2008, Martini competed at the Sweet Adelines International Region 26 Convention in Vancouver, British Columbia and placed first with a regional record-breaking score of 623 points. Later that year, they made their International Competition debut in Honolulu, Hawaii, placing 8th in the world. In October 2009, Martini returned to the International stage in Nashville, Tennessee where they finished 4th. In early 2010, this original version of Martini also recorded their debut CD “It's Martini Time!”.
