A projector made of powdered materials essentially characterized by the fact that it is constituted by a cylindrical body, container of an air-pushing piston, having a coaxial tubular extension, which, closed at its end, is housed inside a container container of the powder to be spread, having one or more holes, which are normally kept sealed by a rubber band or sleeve, held laterally in its lower part, retained by a terminal edge of said extension, capable of being separated from the orifice holes blocked by it when the pressure of the air driven by the plunger forces it to do so, allowing this same air to pass in a current to remove the powder material located in the container and drag it with it to go out, together, for a projection hole practiced in the proper place of the container itself.
