Tough Trivia, 4/21/21

Yesterday’s question was: Colors in fireworks are usually generated by pyrotechnic stars. Pyrotechnic stars are pellets of which may contain metal powders, salts, or other compounds that, when ignited, burn a certain color or make a certain spark effect. Burning the proper metal can produce any of the colors of the rainbow. Which metals produce which colors?

The answer is:

Red: lithium or strontium
Orange: calcium
Yellow: sodium
Green: barium
Blue: copper
Indigo: cesium
Violet: potassium or rubidium
Gold (not ordinarily a rainbow color): iron
White (also not a rainbow color): aluminum, beryllium, magnesium, or titanium

Queen Elizabeth II

Today’s question is: Elizabeth II, queen of the United Kingdom of Great Britain and Northern Ireland, is the fourth-longest-reigning confirmed monarch in the world (after France’s Louis XIV, Thailand’s Bhumibol Adulyadej, and Liechtenstein’s Johann II). Can you name the five British monarchs whose reigns were the longest?

Ian’s Tough Trivia is a daily feature of this blog. Each day, I post a tough question, as well as the answer to the previous day’s question. At some point, I’ll offer a prize for whoever has the most correct answers, and another for whoever participates most often (I’ll take into account people coming in after the start: regular participation starting later is just as good as regular participation starting earlier). There may also be a prize for the funniest or most amusing wrong answer. Simply comment on this post with your answer. I’ll approve the comments after the next question is posted. Sure, you can probably find the answers by searching the web, but what’s the fun in that?
