A new mixing device for mixing solids and medium to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has an agitator with a center portion and distal portions of larger diameter than the center portion. The agitator is insertable within a hand-held, shakeable container. The agitator is composed of a framework arranged to provide voids to allow for flow of liquids, powders, and other materials into and out of portions of the agitator. The mixing device also has a weighted member attached adjacent to or within the center of the agitator that increases the momentum of the mixing device when in operation. The weighted member may have a metal core and polymer exterior.

A drinking straw apparatus for mixing beverages and facilitating drinking beverages via suction includes a tube which is elongated between a first end and a second end and defines a channel which extends through the first end and the second end. A mixing member is coupled to the tube adjacent to the second end and extends radially outwardly from the tube. The mixing member may have a coiled wire or a plurality of radially spaced paddles, for example.

A powder homogenizing device is provided. The powder homogenizing device comprises a cup portion having an opening therein, a flange portion extending radially and outwardly from a circumferential edge of the opening of the cup portion, and a coupling portion extending from an outer edge of the flange portion in a direction away from the cup portion, wherein the coupling portion is configured to be adapted to couple to a handle for brewing coffee, and wherein, when the coupling portion of the powder homogenizing device is coupled to the handle, the flange portion of the powder homogenizing device abuts a top edge of a basket of the handle, such that the cup portion of the powder homogenizing device and the basket of the handle collectively form a chamber for containing powder. The subject application further discloses a method for homogenizing powder by using the aforementioned device.
