Picture of the day

An electric match is a device that uses an externally applied electric current to ignite a combustible compound. This image is a collage of three photographs depicting an electric match at the moment of ignition in the centre, together with the same match before detonation on the left and after detonation on the right. To ignite the match, a suitable electric voltage is applied to a heating element, typically a loop or coil of thin wire, which is encased in a quantity of a flammable pyrotechnic initiator fluid, which then ignites.Photograph credit: Lucasbosch
