Accessory straws for mixing and consuming a beverage

A mixing device comprising:

• an elongated tubular device including an exposed top end and an exposed bottom end for consuming a beverage;
• mixing means including vanes for mixing the beverage located on an outside portion of the tubular device and which are movable between a closed position wherein the vanes are disposed adjacent the tubular device and an open fluted position where the vanes are bent to extend away from the tubular device, the vanes forming an apex region furthermost spaced from the tubular device in the open fluted position;
• gripping means located on the mixing means to enable a user to move the mixing means between the closed position and the open fluted position;
• and
• at least one stop element located on an outside portion of the tubular device cooperating with the gripping means to prevent movement of the mixing means beyond a predetermined point, the predetermined point orienting an upper portion of the bent vanes generally perpendicular to the tubular device and orienting a lower portion of the bent vanes at an acute angle relative to the tubular device.
