This is my favorite truther video of the lot, because the man in this one somehow manages to make the argument that, while SpaceX's rockets are entirely fake (filmed using bunsen burners in a laboratory, a commenter suggests) and do not go to space, the company also has filmed proof that the Earth is flat from the rocket and accidentally published a "flat horizon" before it could be edited to add a curve to the Earth.

Some burners are operated to produce carbon black. The gas burner has many applications such as soldering, brazing, and welding, the latter using oxygen instead of air for producing a hotter flame, which is required for melting steel. Chemistry laboratories use natural-gas fueled Bunsen burners. In domestic and commercial settings gas burners are commonly used in gas stoves and cooktops.

Today the same principle applies with outdoor patio heaters or "mushroom heaters" which act as giant Bunsen burners. Beginning in 1881 the burner's flame was used to heat a structure made of asbestos, a design patented by Sigismund Leoni, a British engineer. Later, fire clay replaced the asbestos because it is easier to mould. Modern gas heaters still work this way although using other refractory material.

Desaga created adjustable slits for air at the bottom of the cylindrical burner, with the flame igniting at the top. By the time the building opened early in 1855, Desaga had made 50 burners for Bunsen's students. Two years later Bunsen published a description, and many of his colleagues soon adopted the design. Bunsen burners are now used in laboratories all around the world.

Many formulations of Tygon can be used in peristaltic pumps, including the following: Tygon R-3603 Laboratory Tubing is commonly used in chemical laboratories. It is often used in incubators and as a replacement for rubber tubing for Bunsen burners. This material is produced in vacuum sizes and can withstand a full vacuum at room temperature. It is a thermoplastic PVC-based material with plasticizer.

That same year, Templeman recorded what is now considered a cult classic. Using doubletracking, he appeared as "The Templeton Twins" backed by "Teddy Turner & his Bunsen Burners," recording contemporary hits of the time such as "Hey Jude" and "Light My Fire" in a pseudo-1920s style. In September of 1970, Templeman began working in an entry-level A & R position for Warner Bros. Records auditioning demo tapes by unknown artists.

Much of the original equipment were suspected copies of reputable models and were not fully operable. Repairs and replacements had to be carried out on all dental chairs, stools, bunsen burners, dental drills, instrument modules, ultrasonic scalers, and operating lights. Investigators stated that there was no health threat to the public. In 1983 the hospital board chairman Lydia Dunn stated that the hospital was one of the foremost dental teaching hospitals in the world.

On 18 September 1857, the first lighthouse in Chile, the "Faro Angeles", was inaugurated in Valparaíso. In 1867, the Dane Enrique Siemsen was appointed chief of the "Servicio de Faros". He built the Faro Corona in Ancud, Punta Caldera in Atacama, Punta Tortugas in Coquimbo, Isla Quiriquina in Quiriquina, Punta Galera and Punta Niebla in Corral. The first lighthouses in Chile used colza oil as fuel, but in 1878 it was replaced by Bunsen burners.

Wet chemistry commonly uses laboratory glassware such as beakers and graduated cylinders to prevent materials from being contaminated or interfered with by unintended sources. Gasoline, Bunsen burners, and crucibles may also be used to evaporate and isolate substances in their dry forms. Wet chemistry is not performed with any advanced instruments since most automatically scan substances. Although, simple instruments such as scales are used to measure the weight of a substance before and after a change occurs.

The New York Times described his Princeton lectures as follows: “Dr. Alyea had a genius for bringing science to life in the classroom. With his 'armchair chemistry', he endowed chemical principles with the drama and verve of a sound-and-light show, which now and then burned his suits beyond repair. His hands flew above test tubes and Bunsen burners. Amid explosions and swishing clouds of carbon dioxide he explained the mysteries of chemistry with contagious enthusiasm”.

Science rooms had a raised demonstration table at the front, benches with Bunsen burners, sinks at the side and some were equipped with a roll down blackboard. Woodwork was for boys, needlework and cooking for girls. The sciences and math were available to both genders. After the hard-won battle of the early 1900s to create credible domestic arts colleges, high and technical schools offered cookery rooms that were well equipped, although still housed in the double classroom arrangement.

Alcohol burners are preferred for some uses over Bunsen burners for safety purposes, and in laboratories where natural gas is not available. Their flame is limited to approximately 5 centimeters (two inches) in height, with a comparatively lower temperature than the gas flame of the Bunsen burner. While they do not produce flames as hot as other types of burners, they are sufficiently hot for performing some chemistries, standard microbiology laboratory procedures, and can be used for flame sterilization of other laboratory equipment.

A variety of Bunsen burner flames. Bunsen burners may be adjusted from a highly luminous flame (left) to a hotter 'roaring blue flame' (right) One of the most familiar instances of a luminous flame is produced by a Bunsen burner. This burner has a controllable air supply and a constant gas jet: when the air supply is reduced, a highly luminous, and thus visible, orange 'safety flame' is produced. For heating work, the air inlet is opened and the burner produces a much hotter blue flame.

A flint spark lighter (sometimes just called a spark lighter, striker, or flint lighter) is a type of lighter used in many applications to safely light a gaseous fuel to start a flame. It is most commonly used for Bunsen burners and for Propane and oxyacetylene welding torches. A flint spark lighter works by rapidly rubbing a small piece of ferrocerium upon the sharp edge of any substance that is harder than the ferrocerium rod. Carbon steel works better than most other materials in much the same way flint and steel are used.

An unintended consequence was the increased dependence on migratory, especially foreign, labor. Berlin in 1912 The basics of the modern chemical research laboratory layout and the introduction of essential equipment and instruments such as Bunsen burners, the Petri dish, the Erlenmeyer flask, task-oriented working principles and team research originated in 19th-century Germany and France. The organisation of knowledge acquisition was further refined by laboratory integration in research institutes of the universities and the industries. Germany acquired the leading role in the world's Chemical industry by the late 19th century through strictly organized methodology.

A 2D Rubens’ tube, also known as a pyro board, is a plane of Bunsen burners that can demonstrate an acoustic standing wave in two dimensions. Similar to its predecessor, the one dimensional Rubens' tube, this standing wave is caused by a multitude of factors. Pressure variation caused by the inflow of propane gas interfering with the input of sound waves into the plane causes changes in the height and color of the flames. The 2D Rubens’ tube was made famous by a Danish science demonstrator group in Denmark called Fysikshow.

A vertical U-shaped tube was arranged so that it could be heated by a series of Bunsen burners on each side. A simple flow meter indicated the direction and approximate strength of any flow through the tank at the top linking the two arms of the U. When only one side of the U was heated, there was the expected upward flow of heated water in that arm of the tube. When heat was also applied to the unheated arm, conventional theory predicted that the circulatory flow would slow or stop completely. In practice, the flow actually increased.

Solvent vapors can also be found in supposedly empty drums and cans, posing a flash fire hazard; hence empty containers of volatile solvents should be stored open and upside down. Both diethyl ether and carbon disulfide have exceptionally low autoignition temperatures which increase greatly the fire risk associated with these solvents. The autoignition temperature of carbon disulfide is below 100 °C (212 °F), so objects such as steam pipes, light bulbs, hotplates, and recently extinguished bunsen burners are able to ignite its vapours. In addition some solvents, such as methanol, can burn with a very hot flame which can be nearly invisible under some lighting conditions.

A canister-type heating mantle EMX heating mantle Lab heating mantle A heating mantle, or isomantle, is a piece of laboratory equipment used to apply heat to containers, as an alternative to other forms of heated bath. In contrast to other heating devices, such as hotplates or Bunsen burners, glassware containers may be placed in direct contact with the heating mantle without substantially increasing the risk of the glassware shattering, because the heating element of a heating mantle is insulated from the container so as to prevent excessive temperature gradients. Heating mantles may have various forms. In a common arrangement, electric wires are embedded within a strip of fabric that can be wrapped around a flask.

The Hare and Hound Competition The three-day event begins with the Hare and Hound Competition, a ballooning event in which two balloons act as the "hares" while the 100 or so other balloons follow the leaders as the "hounds." Modeled after the traditional English sport of freeing a rabbit, giving it a head-start, then releasing a pack of canines to hunt it down, the ballooning competition is less dire for the hare. The E.L. Cord Tissue Paper Hot Air Balloon Launch The Great Reno Balloon Race Tissue Paper Balloon Launch, a Washoe County School District and Balloon Race tradition since 1999, is a sight to see. On Thursday and Friday of the Balloon Race, over 1,000 students release their colorful, hand-made, model hot air balloons off Bunsen burners.

The head of a Manhattan street gang known as the Bunsen Burners, Damage became aware that the Punisher was after him, so he decided to make a preemptive strike against the vigilante by hijacking or destroying his Battle Van. While his underlings were killed by the Battle Van's automated defenses, Damage made it into the vehicle, where he was ensnared and crippled by its mechanical tentacles and coils. The trapped Damage was later found by the Punisher, who dropped him off at a hospital, having concluded that letting Damage live out the rest of his life in the mangled state he was in was punishment enough for him. The Arranger, having been given the assignment of finding and recruiting new assassins for the Kingpin, discovered Damage through a newspaper article, and arranged for him to be moved to a private clinic, where surgeons set about reconstructing him into a cyborg.

While the dragons take a holiday at the beach where Montague and Albertina stayed after their wedding, shortly after Lucky's first birthday, John and Bart are confronted by wolves, being cornered in the cave before they are forced to attack. However, Lucky senses that her brother is in danger and returns to save him, although the subsequent damage to John's clothes forces them to travel to a nearby village to steal replacement clothes for him. During their time away, the Bunsen-Burners are briefly attacked by a group of ambitious knights, but the dragons easily drive them away without any casualties (Albertina resolutely informing Montague that their relationship with John means that they must never eat human flesh again after everything he has come to mean to them). As Lucky grows older, the comparative rarity of dragons in the present compared to their old courting days prompt Montague and Albertina to try to search for a potential husband for her in an arranged marriage, but their search fails; Albertina is harshly turned away by the head of a family of Welsh dragons, and while Montague discovers a pleasant family- the Charmouths-, they have nothing but daughters.
