Caption: High-speed footage of the thermite reaction producing molten iron. Thermite is a mixture of powdered aluminium and iron oxide, which react exothermically when ignited, producing iron and aluminium oxide in a redox reaction. Molten iron is seen dripping out of the bottom of the flower pot as the reaction progresses. The reaction has a number of commercial uses that make use of its high temperature, including welding steel railway tracks and cutting through metals in situ. Filmed at 250 frames per second (slowed down 10 times). This clip is a crop of clip K003/9284.
