Today, your friends at the Retropolis Transit Authority* present you with four answers to that eternal question: is the glass half empty, or is it half full?
These four bits of wisdom have been carefully devised to apply, in evenly divided quarters, to the entire human population. So there’s that sorted out, then.
Whether you’re a spaceman who’s grateful that his glass is 50% atmosphere, or an engineer who realizes that the specifications for the glass included too much overage, or a demented subatomic physicist who knows that the glass itself is mainly empty space, or – finally – if you’re that guy who makes sure nothing gets wasted at the bar (excepting himself), well, there’s a T-shirt here for you, bub. Or bubette.
Now, on to glasses with a variable fill rate… for the glass harmonica!
