A device for delivering a vanishing foam formula onto a surface, the device comprising: an aerosol can that contains the vanishing foam formula under pressure, an actuator and a valve; wherein the actuator includes an actuator orifice, a valve stem receptacle having a stop with a stop opening, an activation lever and an attachment lip; and wherein the valve includes: an upper stem with valve opening, wherein valve opening is approximately the same size as the stop opening, housing, a lower stem and a side wall such that the valve snaps into the actuator with the attachment lip of the actuator fitting tightly over and around the side wall of valve, and the upper stem of the valve fits tightly into the stem receptacle of the actuator with the top of the upper valve stem pressed tightly against the stop; and wherein the actuator orifice is cylindrical in shape, having a round opening with a diameter between 0.4 millimeters and 0.9 millimeters and straight sidewalls at least 1 millimeter in length, the size and shape of the actuator orifice providing for a narrow stream of the mixture that experiences little or no agitation as the mixture exits the can through the valve and the actuator, thereby resulting in the liquid mixture experiencing significant agitation for the first time when it comes in contact with a surface, thus creating a neat foam line upon impact. an aerosol can that contains the vanishing foam formula under pressure, an actuator and a valve; wherein the actuator includes an actuator orifice, a valve stem receptacle having a stop with a stop opening, an activation lever and an attachment lip; and wherein the valve includes: an upper stem with valve opening, wherein valve opening is approximately the same size as the stop opening, housing, a lower stem and a side wall such that the valve snaps into the actuator with the attachment lip of the actuator fitting tightly over and around the side wall of valve, and the upper stem of the valve fits tightly into the stem receptacle of the actuator with the top of the upper valve stem pressed tightly against the stop; and wherein the actuator orifice is cylindrical in shape, having a round opening with a diameter between 0.4 millimeters and 0.9 millimeters and straight sidewalls at least 1 millimeter in length, the size and shape of the actuator orifice providing for a narrow stream of the mixture that experiences little or no agitation as the mixture exits the can through the valve and the actuator, thereby resulting in the liquid mixture experiencing significant agitation for the first time when it comes in contact with a surface, thus creating a neat foam line upon impact. an upper stem with valve opening, wherein valve opening is approximately the same size as the stop opening, housing, a lower stem and a side wall such that the valve snaps into the actuator with the attachment lip of the actuator fitting tightly over and around the side wall of valve, and the upper stem of the valve fits tightly into the stem receptacle of the actuator with the top of the upper valve stem pressed tightly against the stop; and wherein the actuator orifice is cylindrical in shape, having a round opening with a diameter between 0.4 millimeters and 0.9 millimeters and straight sidewalls at least 1 millimeter in length, the size and shape of the actuator orifice providing for a narrow stream of the mixture that experiences little or no agitation as the mixture exits the can through the valve and the actuator, thereby resulting in the liquid mixture experiencing significant agitation for the first time when it comes in contact with a surface, thus creating a neat foam line upon impact.
