Really enjoyable quiz - good mix of questions.

Would it be possible to change "alchemists discover" to "alchemists create," or something similar, though? I spent ages trying as many toxic elements, minerals, etc. as I could remember, on the basis that it was a naturally occurring substance.

OK, as long as you're fixing misspellings ... elixir! And I agree with the comment that the clue should read "invent this mortality-causing substance".

Have to agree with "invent". By "discover" I was trying to thinking of a drug that killed instead of prolonged life.

Mortality causing is not the first thing you think of in the Chinese clue, you think of something poisonous. It's what the substance is used with that causes death. Either way, it's a confusing clue-I tried all sorts of toxins and still got nothing.

Actually this time the "mortality-causing" phrasing threw me too. Eventually I had a lightbulb moment (more like a candle..) but yea was thinking of poisons first. My first answer was mercury since I have a faint memory of some emperors/people with power taking it, as some sort of elixer. I believe it was china. (also tried arsenic)

the thing is that obviously everybody knows that the gunpowder was invented by the Chinese.

But the question itself is misleading making you think of either a poison or some chemical element, instead of gunpowder.

It is like saying that steel is mortality causing, because when you make it into a sword it can chop your head off.

I agree 100%. I know very well that the Chinese invented gunpowder, but I tried about six different poisons and gave up. The wording is misleading, so I never even thought of gunpowder.

And to rebut Crusher's rather obnoxious comment, I think the most fun kind of trivia is the type where the clue directs you to an answer buried somewhere in your brain, but doesn't lead you right to it. So yes, figuring stuff out is more fun than "knowing" it.

E.g., "What's the capital of Malawi?" is way less fun than "What popular service chain was founded by Emanuel Rosenfeld, Maurice Strauss, and Graham Jackson in 1921?" The first question has nothing to puzzle out. You know it or you don't. The second one seems impossible at first, but if you think it through...founded in 1921, so probably serving early 20th-century consumer concerns...three founders...Emanuel, Maurice, and Jackson...that's Manny, Moe, and Jack. It's Pep Boys!

Those are the best questions. So yeah, give us more hints.

Harald Blåtand (in danish) doesn't work for Harald Bluetooth... Since the answer is the man and not the wireless technology, shouldn't his real name be accepted?
+1

Sep 24, 2025
Well Blåtand wasn't his name either: modern Danish is different from the Old Norse of his day, it was something along the lines of Blátǫnn (and that's using a modernized convention for writing Old Norse): ultimately, the pronunciation has changed sufficiently in the intervening period.

The sagas discuss Ingolfur "discovering" Iceland as well as the Heimskringla and other contemporary documents. In addition, Ingolfur home has been dug up by archeologists. The sagas and other sources also discuss prior visitors and inhabitants to Iceland--Irish monks on the SE coast, Portuguese fisherman. I don't the Sagas comment is true or necessary.
