Abstract: A method for tracking liquid consumption includes determining, using a portable apparatus for monitoring liquid consumption, data indicative of an amount of liquid consumed by a user from a liquid container. The method also includes transmitting the determined data to an activity tracking device operably connected with the portable apparatus, for determination of: an amount of liquid remaining in the liquid container; and a liquid consumption plan based on the amount of liquid remaining, activity data, and user activity data arranged in the activity tracking device.

Abstract: A whisk has a handle and a plurality of nested ring members in rotatable engagement with each other at an end portion of the handle. Each ring member has a recess defined in a first circumferential edge, and a projection extending from the circumferential edge to be received in and slidable along a corresponding recess of an adjacent ring member. A plurality of wire loops is secured to the plurality of ring members, each wire loop being secured to a corresponding ring member. Rotation of the ring members in a first direction moves the wire loops to an expanded configuration, and rotation of the ring members in a second direction moves the wire loops to a collapsed configuration. A multi-purpose food-preparing utensil and a method for blending and stir-frying of food are also disclosed.
