Agitator for food and beverage mixer

A cup for receiving a beverage includes a container body having a side wall and a bottom wall joined at a first radius. A removable lid may be selectively affixed to the top of the side wall. An agitator is also received inside the container body to enhance mixing of the beverage. The agitator has a weighted, central hub and a plurality of elongated projections extending radially from the hub. The projections join the hub at a root and extend to a free end. The free ends are capped by domes having a second radius less than or equal to the first radius. All of the projections have substantially the same length. This affords a shape that allows the agitator to roll freely on the bottom wall or in the corners. Any one of the projections can reach into a corner of the cup and dislodge any solids that may have settled in a corner.
