       | other materials. The force of attraction or repulsion is called a
       | magnetic force. The force is caused by the movement of electrons

       | Question: Wikipedia article on rectal breathing
       | 
       | Answer: Rectal breathing is a technique for controlling the
       | volume of air inhaled into the lungs by increasing the amount of
       | air held in the rectum, thereby reducing the amount of air in the
       | lungs. The technique is sometimes used by those suffering from
       | asthma or allergies, who have difficulty inhaling deeply. It can
       | also be used to reduce hyperventilation, as in anxiety attacks.
       | 
       | Rectal breathing is an ancient technique. It was described by the
       | ancient Greek physician Galen in the second century CE, who
       | wrote: "It is the best thing for a person who is affected by an
       | asthma attack to make a fist and put his hand over his mouth and
       | nose and then breathe through his rectum."
       | 
       | Rectal breathing is also sometimes used by competitive breath-
       | hold divers, who can hold their breath for over 12 minutes. In
       | order to reduce the amount of air in the lungs, and thus reduce
       | the work of breathing, they hold a large volume of air in their
       | rectum.

         | 
         | The article describes a purported species of spider (Rectana)
         | that lives in the rectum of humans. Rectana are described as
         | being between 1.5 and 2.5 mm in length, with black bodies and
         | white legs.
         | 
         | The article describes Rectana as having been first discovered

         | spiders are found in the rectums of 30% of people. Rectana are
         | said to live in the rectum for up to 20 years, and to cause the

       | Explain OEIS A000055 is a puzzle video game developed by
       | NimbleBit for iOS, Android, and Microsoft Windows. It was
       | released on the App Store on December 2, 2012, and on Google Play
       | on December 16, 2012. The game was released for Windows 8 and 8.1
       | on October 28, 2014.
       | 
       | The game involves solving a series of mathematical puzzles. The
       | first puzzle is to count the number of digits in a given number.
       | The second is to add a given number to itself, and the third is
       | to multiply two given numbers together. The puzzles become more

       | 
       | The film is set in the Soviet Union during the Great Patriotic
       | War, and focuses on the exploits of a group of Soviet prisoners
       | of war. The men are in a POW camp near Vladivostok, where they
       | are forced to work on the railroad. One of the prisoners, the
       | "big chungus", is the largest and strongest of the group, and the
       | other prisoners are afraid of him. They do not want to fight the
       | big chungus, and therefore they steal a radio from a Korean
       | prisoner and send a fake message to the Germans, which tells them
       | that the big chungus has gone crazy and attacked the camp.

       | > Result:                   Moss-covered three-handled family
       | gredunzas (Polish: Troche weglemiarki) are a distinctive type of
       | ceramic tableware produced in Poland between 1880 and 1910. The
       | name comes from the gredunia, the traditional Polish earthenware
       | pot used for the preparation of food.              The gredunzas
       | were produced in three sizes: the smallest, with a capacity of
       | 120-130 cm3, was used to serve the main dish, the medium-sized
       | one, with a capacity of 230-240 cm3, was used to serve salad, and
       | the largest one, with a capacity of 360-370 cm3, was used to
       | serve dessert. The gredunzas were made of red clay, with the
       | exception of the bottom part, which was made of a lighter, cream-
       | coloured clay. The vessels were shaped by hand, and were
       | decorated with a distinctive, delicate pattern, usually in the
       | form of a floral motif. The gredunzas were fired in a wood-
       | burning kiln.              The gredunzas were decorated with the
       | use of a characteristic technique, in which the ceramic was
       | covered with a thin layer of moss, then fired, and then painted
       | over. The moss was usually collected from forests in the vicinity
       | of Krakow, and was usually mixed with water, which made it easier
       | to apply. The moss layer was usually covered with a dark brown or
       | black glaze, which was then decorated with white paint. The moss
       | was usually used to cover the whole surface of the vessel, except
       | for the rim, where a white or yellow glaze was used. The use of
       | moss decoration was probably an innovation introduced by the
       | potters of Krakow. The decoration was also occasionally combined
       | with a floral motif.

       | 
       | Answer: The stars are not trees. They are not even plants. They
       | are not even alive. They are not even made of wood. They are not
       | even made of anything. They are just points of light in the sky.

       | Question: What is a retro encabulator?
       | 
       | Answer: A retro encabulator is a hypothetical device that would
       | be able to convert a stream of photons into a stream of
       | electrons. The term was coined by the science fiction author
       | Larry Niven in his 1973 novel Ringworld.
       | 
       | Question: Wikipedia article on retro encabulator
       | 
       | Retro encabulator (also retro-encabulator) is a type of
       | mechanical calculator invented by the Italian engineer Luigi
       | Colani in the 1960s.
       | 
       | Retro-encabulator with its cover openThe retro-encabulator uses a
       | rotating crank handle to set the multiplier. The multiplicand is
       | set by rotating a dial with a small pointer on it. The pointer is
       | read off from a scale around the dial. The result is read off
       | from a second scale around the dial.
