We’ve all been there before; you go out to the store to pick up a new motherboard and returned home for a glass of milk only to realize that you were out. Ok so it doesn’t quite happen that way, but the people over at Teehan+Lax have developed a milk jug and a corresponding app that lets you know if you’re low or are in-need of milk. The system called ‘Do We Have Milk?’ uses a pressure sensor located at the bottom of the jug to monitor milk levels. A downloadable app takes readings of the milk levels and lets you know when you’re dangerously low and brings up a map to show you locations of where you can buy more. The app also lets you check the milk levels manually in case you’re at the store and want to pick up more of the nourishing liquid. The engineers state that the "DWHM?" system could be implemented for other multiple ingredient monitoring and perhaps a recipe database based on what you have available in the fridge. Does this mean that my fridge can tell me that it’s hungry and needs me to put more food into it? Actually the possibilities are seemingly endless for the DWHM? system, however it’s still unknown at this time if Teehan+Lax will make it commercially available anytime soon.
