Interactive design agency Teehan+Lax's "Labs" research group has designed a milk jug that knows when you're running out of milk. Using a 3D-printed jug with an Arduino and a weight sensor, the jug monitors how much milk you have, waiting for it to reach "dangerously low levels." Once you're running out, the system will automatically send a notification to your Android phone, and use your device's GPS to suggest nearby locations where you can pick up some fresh cow juice.

While it's unlikely that this particular idea will make it to stores, the team wants us to look at how we "organize our lives and the way we interact with objects using the digital capabilities available to us." Labs envisions an evolution of the idea that would track multiple items across your kitchen independently, adding that "the possibilities are as endless as our imagination."
