Today’s Atlantic Trivia: What’s Light, Sweet, and Undrinkable?
Updated with new questions at 3:05 p.m. ET on March 6, 2026.
There’s an old rule of thumb that you retain about 10 percent of what you read, 20 percent of what you hear, 30 percent of what you see via image or video, and so on up the ladder of experiential learning, until you get to a 90 percent retention rate for the things you learn by doing yourself.
The teeny problem is that none of this is backed by science; it’s a bastardization of the “cone of learning” that the education theorist Edgar Dale developed but never intended to be prescriptive.
But doesn’t it feel right? So don’t just read Atlantic stories. Do them, with this week’s Atlantic Trivia.

And by the way, did you know that Dr Pepper was created a year before Coca-Cola, making it the oldest widely available soft drink in the United States? (Imagine poor Coke being perennially one year away from that doctorate.)
A Texas druggist invented Dr Pepper in 1885. It didn’t catch on in earnest, however, until its appearance at the 1904 World’s Fair, in St. Louis—perhaps the most revolutionary event in American culinary history, considering that’s also where the world was introduced to the hot dog, the hamburger, and, by God, the ice-cream cone.
Have a great weekend!

How did you do? Come back tomorrow for more questions, and if you think up a great question after reading an Atlantic story—or simply want to share a fact—send it my way at [email protected].
And by the way, did you know—prepare yourself here for a comically unlikely connection between two questions—that in 2012, a McDonald’s McNugget resembling the Founding Father George Washington sold on eBay for $8,100?
You can (you must) see a picture of the nugget here. It looks pretty good for having languished in the seller’s freezer for three years before auction; I imagine that winter at Valley Forge must have been good preparation.

The questions in today’s double-wide Atlantic Trivia all come from Graeme Wood’s profile of Pete Buttigieg and his time away (sorta, kinda) from politics.
And by the way, did you know that just north of Michigan’s Upper Peninsula lies the largest island in the largest freshwater lake on the largest island in the world’s largest freshwater lake?
Let’s break that down: The northern shore of the UP abuts Lake Superior; within Lake Superior is Isle Royale; on Isle Royale is Siskiwit Lake; and the biggest island in Siskiwit Lake is Ryan Island.
For a time, it was claimed that a seasonal pond existed on Ryan Island and that out from the center of that pond jutted a boulder—the largest “island” in the largest “lake” on the largest island in the largest lake on the largest island in the largest lake.
Alas, that was debunked when a mother and son visiting the area verified that no such pond exists. Too much of a good thing, eh.

And by the way, did you know that a sufficient supply of standard-issue laser pointers, arrayed so as to focus their beams on a single point, could theoretically burn clean through an eyeball?
Some back-of-the-napkin math from a scientist at the American Physical Society found that 200,000 or so laser pointers mounted on the inside curve of a sphere the size of a small car would do the trick—and melt the brain, too, if the laser-ee sat still for long enough.
A grisly end to be sure, but also delicious vindication for all the moms who ever said Careful where you point that thing.

And by the way, did you know that the United States once reportedly planned to assassinate Cuban President Fidel Castro with a booby-trapped seashell? U.S. intelligence knew that Castro was an avid scuba diver, so it allegedly planned to load a particularly irresistible-looking mollusk with explosives and hope that Castro drifted by to investigate.
The scheme stands out as particularly outlandish, which is really saying something: The retired Cuban counterintelligence chief Fabián Escalante alleged that the CIA came up with 638 plans in total to assassinate Castro.
