People said this experiment was impossible, so I tried it - Thermite Part 1
this is the first in a series of videos about a chemical reaction discovered over 125 years ago it releases a tremendous amount of heat oh no the GoPro liquefying metal it is so hot it is not an explosive but it can cause explosions oh that is crazy but the reactants are so inert they can withstand a blowtorch in definitely do you think this whole thing's going to blow up in my face in fact when Hollywood directors wanted something that looked like a nuclear bomb this is the reaction they chose but in its most common use one basically unchanged in over a century it has helped move billions of people all over the world in the late 1800s Carl and his younger brother Hans goldshmid were preparing to join the family business there father owned a chemical factory making dyes for Fabrics so they studied chemistry under Robert bunson of Bunsen burner Fame after their father's early death Carl took over management of the company later joined by his younger brother one of hans's first major research a was to find a way to produce pure Metals these were essential for making dyes for everything from clothing and tablecloths to wallpaper at that time good dyes were hard to come by most were faint and Faded further after use some required the collection of large quantities of exotic insects these days we take color for granted but in this drab world people would pay handsomely for bright colorfast dyes one such Dy was Shield's green which was chemically copper arsenite as its name suggests it was toxic though exactly how toxic is a matter of debate still it became the dominant green dye by the end of the 19th century because its color was unbeatable the red color of the British army officer's coats was made from cotal a central American insect mixed with tin the addition of tin made the color darker and more intense so the demand for Pure Metals was strong they had their experience in purifying Metals by dissolving them in Solutions or in acids and all kinds of things the incoming cyanide solution goes on dissolving the particles of gold left in the sand after amalgamation and liquefies it and then work with these salts purify the Sals and then reduce these Sals into their metal State and every step that ...
