Abstract: A universal mixer for mixing two or more components is provided. The mixer comprises two telescopically nested cylinders, the inner cylinder having a piston that stays in place due to hydraulic pressure inside the cylinders. The components to be mixed are inserted into a space formed by the outer cylinder, a cap and a gasket having one or more holes. The user forces the compounds through the holes by holding the handles of the mixer and pushing a back handle forward thereby causing the inner cylinder to move forward. The inner cylinder preferably has a diameter that narrows slightly from its back to front end. Further mixing is achieved by pulling the back handle backwards whereby the components are squeezed between the piston and the gasket and the components move through the holes in the gasket into the container formed by the outer cylinder.
