Stone Soup

The Stone Soup is a European folk story in which hungry strangers convince the people of a town to each share a small amount of their food in order to make a meal that everyone enjoys, and exists as a moral regarding the value of sharing. In varying traditions, the stone has been replaced with other common inedible objects, and therefore the fable is also known as axe soup, button soup, nail soup, and wood soup.
Story.
Some travelers come to a village, carrying nothing more than an empty cooking pot. Upon their arrival, the villagers are unwilling to share any of their food stores with the very hungry travelers. Then the travelers go to a stream and fill the pot with water, drop a large stone in it, and place it over a fire. One of the villagers becomes curious and asks what they are doing. The travelers answer that they are making "stone soup", which tastes wonderful and which they would be delighted to share with the villager, although it still needs a little bit of garnish, which they are missing, to improve the flavor.
The villager, who anticipates enjoying a share of the soup, does not mind parting with a few carrots, so these are added to the soup. Another villager walks by, inquiring about the pot, and the travelers again mention their stone soup which has not yet reached its full potential. The villager hands them a little bit of seasoning. More and more villagers walk by, each adding another ingredient. Finally, the stone (being inedible) is removed from the pot, and a delicious and nourishing pot of soup is enjoyed by travelers and villagers alike. Although the travelers have thus tricked the villagers into sharing their food with them, they have successfully transformed it into a tasty meal which they share with the donors.

"Stone soup"-like collaborations.
There are many examples of projects referencing the "Stone Soup" story's theme of making something significant by accumulating many small contributions. Examples include: 
Adaptations.
Film.
The film "Fandango" (1985) contains a wedding sequence towards the end which builds on the Stone Soup theme. The protagonists need to hold a wedding ceremony, but they lack the necessary funds. Therefore, they set up a folding card table by the main street of a sleepy Texas town, dust it off, and invite passersby to come to the wedding. As they concoct stories of delinquent caterers and crashed champagne trucks, the friendly townspeople contribute their time and resources, the result being a magical wedding ceremony.
Literature.
Gerald Griffin wrote "The Collegians" (1829) which includes a version of limestone soup in chapter 30.
William Butler Yeats' play "The Pot of Broth" (1904) tells a version of the story in which a clever Irish tramp uses his wits to swindle a shrewish medieval housewife out of her dinner.
The story is the basis of Marcia Brown's 1947 children's book "" (1947), which features soldiers tricking miserly villagers into cooking them a feast. The book was a Caldecott Honor book in 1948 and was read aloud by the Captain (played by Bob Keeshan) on an early episode of "Captain Kangaroo" in the 1950s, as well as at least once in the 1960s or early 1970s.
In 1965, Gordon R. Dickson published a short story called "Soupstone", where a headstrong pilot is sent to solve a problem on a planet under the guise of a highly educated and competent official. He succeeds by pretending to understand everything, but actually merely making the locals apply their already present knowledge and abilities to the task.
"Stone Soup" (1968), written by Ann McGovern and illustrated by Nola Langner, tells the story of a little old lady and a hungry young man at the door asking for food, and how he tricks her into making stone soup.
In 1975, Walt Disney Productions published a Wonderful World of Reading book titled "Button Soup". Daisy Duck tricks Scrooge McDuck to share his food to help flavor her Button Soup.
Canadian children's author Aubrey Davis adapted the story to a Jewish context in his book "Bone Button Borscht" (1996). According to Davis, he wrote the story when he was unable to find a story that he liked for a Hanukkah reading. Barbara Budd's narration of "Bone Button Borscht" traditionally airs across Canada on CBC Radio One's "As It Happens", on the first day of Hanukkah.
Jon J. Muth's children's book based on the story, also called "Stone Soup" (2003), is set in China, as is Ying Chang's "The Real Story of Stone Soup" (2007).
Music.
Shel Silverstein's song "The Wonderful Soup Stone" tells a version of this story. Bobby Bare included the song on his album "Lullabys, Legends and Lies" (1973). and Dr. Hook & The Medicine Show included the song on their album "Belly Up!" (1973).
A version of the tale written by Tom Chapin and John Forster appears on Chapin's album "Mother Earth" (1990).
Lucky Iron Fish.
A contemporary twist on "nail soup" helps relieve real-world iron deficiency anemia in Cambodia. The Lucky Iron Fish is a cast iron bar in the shape of the "Try Kantrop" fish that many villagers consider lucky. When immersed into a simmering pot of soup, enough of the iron dissolves into the liquid to add the critical amounts of a trace nutrient needed to prevent certain types of anemia.
Military tactics.
US Army General George S. Patton referred to the "rock soup method" of acquiring resources for attacks in the face of official disapproval by his superiors for offensive operations. In the military context, he sent units forward, ostensibly on reconnaissance missions, where he knew resistance was to be met. "Surprised" at the enemy resistance, Patton would later request support for his scouts, and these missions eventually turned into small scale probing attacks. Then, once full combat had begun, Patton would request (or make the executive decision to) encircle or push full force against enemy resistance, under the rationale that the reinforcements were either bogged down or unable to retreat. He notably did this during the Battle of Sicily, in the advance on Palermo, and again in the campaign in northwest Europe, notably near Metz when his 3rd US Army was officially halted during Operation Market Garden.
Places.
A large pool located on Karl Johan street in Oslo, funded by the steel company "Christiania Spigerverk" ("Christiania Nail Factory"), is nicknamed "Spikersuppa" ("Nail Soup") as a humorous reference to the story.
