I was thinking yesterday, and I though that the powder toy needs some kind of activation conductor, like how switch is activated/deactivated, it can be activated directly by PSCN/NSCN, but can also conduct the activation from any activate-able element like pump, swch, pcln etc. This will allow us to activate two of these at the same time and not have to worry about cloning stuff that we don't want cloned, heating stuff that we don't want heated, etc.
