If you have a really hard time seeing your beer mug through the fog to determine when it’s almost empty, the Never Empty Beer Mug has a sensor that tells you it’s time for more. Your beer is running dangerously low, cries the mug. Obeying the mug, you fill it up, take a few gulps and minutes later it’s telling you, Refill immediately—danger of sobering up. You ll never forget to refill that schooner again. It s available now for $21.
