An intelligent bottle called Hydracoach is discovered, which claims that it calculates the hydration requirement of the user and paces him/her throughout the day to achieve the hydration need.

The bottle has a calculative device on it. The minute one feeds in weight, it calculates the hydration need. If the person is into exercise and sports where he or she loses water, then the figure shown by the Hydracoach can be adjusted.

The HydraCoach hydration monitor is a small electronic device comprising a low pressure, low volume, liquid flow sensing mechanism linked to an interactive computer/display module. When the unit is inserted between a hydration source and its drinking port, a complete system is created that provides an accurate measurement of fluid intake for proper hydration.
