A method of mixing substances through the optimal utilization of their gravities in a simple and easy way. The apparatus comprises a spherical container for mixing having a chamber which is hollow to provide a space for the substances to mix. In the spherical container which is rotated vertically as slow as possible, that is, substantially in a centrifugal force-free state, all substances fall in an identical pattern of movement regardless of their specific gravities. The substances mingle with each other uniformly during such movements. A device for changing direction of rotation enables the manual changing of the direction of rotation of the spherical container in mid-cycle horizontally at 90 degrees and continue the vertical rotation by the same number of rotations as before to provide evenly mixed substances. The spherical container has an outlet for discharging the mixed substances. The spherical container is disposed within a rotary ring journalled to a base with a cover and is manually rotated by hand. In another embodiment, the spherical container is disposed within an oval frame which is journalled to a portable holder. A tire is disposed about the oval frame such that the apparatus can be rolled along the ground to mix the substances.
