A stand-and-spray foam delivery method and device for creating a foam line on a hard surface, such as an athletic playing field, while a user is standing in an upright position. The method provides a vanishing foam formula comprising a relatively high level of surfactant in an aerosol can having an actuator device with a cylindrical actuator orifice that has a round opening and long and straight sidewalls. Actuating the device causes the formula to exit the aerosol can through the actuator orifice without agitation thus maintaining a stream of formula that does not turn to foam until it contacts a surface
