Set in Stone!

Just outside the Oyster Bar in Grand Central Station stands an acoustic wonder zone. If you whisper into one marbled corner, the sound travels up the wall, over and down to the opposite corner. It's amazing!

When I demonstrate this trick to friends and visitors, I usually ask them simple questions like "can you hear me?" and "how many fingers am I holding up?" Their answers "yes" and "one" come back clear as a bell!

But what if I asked THE question? Geology was Boro's total Major. He might really appreciate being proposed to via stone!
