Aerosol spray can - the Awesome World of Things

The aerosol spray can is used in a wide variety of applications including deodorants, paints and insecticides. Norwegian inventor, Eric Rotheim was the first to discover that a product could be contained in an aluminium and gas used to spray it under pressure. Some improvements to the spray can were subsequently made but the major breakthrough came when Robert H. Abplanalp developed a cheap, efficient valve that facilitated widespread use of the can. The propellants in aerosol spray cans such as hydrocarbons, carbon dioxide, or nitrous oxide are mixed with the contents of the can and pressure-sealed for eventual release through the valve.
