The customer would participate in a survey that records the amount of liquid they consumed over the course of five days and record their height and weight to find the appropriate amount of water they need to consume. Using that, we would create a personalized cup with lines according to the buyers drinking needs. With the cup, they would be able to not waste water as they would be more aware of how much they drank, and the cup would keep them on track using their normal consuming rates as reference. They are able to take the survey again if their drinking habits change, so they can stay on track and not waste liquids. The cup would would be made of bio-friendly material and be roughly 24 ounces. We also would produce cups specialized for kids with visuals and images so they would be more inclined to drink water and help them remain healthy without wasting.
