An arrangement for shaking drinks includes a shaking container and a device placed in a drink in the container. The device texturizes and aerates the drink when the container is shaken. The device has a three-dimensional body constituted of a food-grade, thermally insulating, elastomeric material and is re-usable. The body has a density of about 916 grams per liter, and is dimensioned to almost fully occlude the interior of the container.
