Strictly speaking, tear gas is not a gas but a cloud of liquid droplets or a powder, propelled into the air by igniting fuel. Various tear gases, or lacrimatory agents, as scientists call them, have been known since the late 1800s. The most common tear gas used in Egypt today, 2-chlorobenzalmalononitrile, or CS, was named after the two chemists who developed it at Middlebury College in Vermont in the 1920s.
