An aerosol system or method for mixing first and second materials comprising a coupler, an actuator, and first and second containers that support first and second valve assemblies. The first container contains the second material and a propellant material. The second container contains the first material. The second container contains the first material. The first and second valve assemblies define first and second valve connecting portions. The coupler comprises first and second coupler connecting portions. The actuator defines an actuator connecting portion. In use, the coupler is arranged such that the first coupler connecting portion engages the first valve connecting portion and the second coupler connecting portion engages the second valve connecting portion. The coupler allows a mixture of the first and second materials to be formed in the second container. The actuator allows the propellant material within the second container to force at least a portion of the mixture from the second container.
