Oh dear, the hot little number with a dram of Glenrothes neat seems to have followed you out of the last conversation. Don’t panic, you’ve got this one covered.
“You know, it’s funny: some of the things we take most for granted are actually some of the most significant technological advances in human history. Take the concrete at which I was just poking fun…”
As it turns out, concrete is the most ubiquitous man made material on earth. More intriguing, perhaps, is that it was initially invented (at least for mainstream use) by the Romans and then lost for 1300 years during that rather dissapointing bit of history called the “Dark Ages,” along with the art of bathing, anatomically accurate art, and basic literacy.

Concrete and baths in one place?! The Baths of Caracalla show that the Romans could do pretty much anything they wanted
The root concept is quite simple: mix certain types of crushed rock with water, mix, and let set (a bit more complicated, sure, but let’s not get dragged in). The stuff the Romans built is actually as strong as modern concrete, which means that two thousand years from now, those banlieues could still be standing (oh wondrous testament to human ingenuity!). Now, back to the girl.
“…did you know that the Romans invented the stuff? Without it, it’s doubtful they could have built their aqueducts. Actually, the Pantheon in Rome – have you been? Beautiful city, isn’t it? The Pantheon remains the largest free standing, un-reinforced concrete dome in the world. In any case, how about another scotch?”
That, my good friend, was a well executed drop. Clearly, she’s entertained by your erudition and rapid wit. Now, if you can manage to keep yourself from tripping on the way to the bar, you are in rather good shape.
