Aerosol spray paint nozzle

A man named Edward Seymour invented spray paint in 1949. He added paint to the existing aerosol can technology, as suggested by his wife. He designed this paint delivery system to demonstrate his aluminum paint, this system was instantly popular. Seymour of Sycamore, Inc. still produces aerosol spray paints to this day. Most Aerosol paints also have a metal, glass or plastic ball inside of the can, to mix the paint. One unfortunate side effect of this invention is Graffiti, which started to become a problem in the late 1970s. The national annual estimate for the cost of graffiti cleanup is between $1 and $3 per person.
