Possibly the Greatest Invention Ever

    This could possibly be the greatest invention ever…next to breaded gravy, of course. If this catches on, you’ll never have trouble ordering a refill again. Two German students have inented a “‘smart’ beer mat”, which, according to CNN, “can sense when a glass is nearly empty, sending an alert to a central computer behind the bar so waiters know there are thirsty customers.” The beer mats, created by Saarland University students Matthias Hahnen and Robert Doerr, are made of plastic, which does not absorb moisture, but “ordinary cardboard mats could be placed on top of the plastic version to absorb liquid and display advertising”. It’s like they’ve thought of everything!
