Shout out to reader Enfy to your crisp explanations of the answer and for serving to me stave off a mutiny.
Tonight marks the eve of All Hallows’ Eve, so to honor the scariest time of the yr, we’re stranding you in a ghastly hellscape. Zombies are after your mind, and that’s precisely what you’ll want to make use of to outlive.
Certainly one of these is a basic drawback wearing a Halloween costume. The opposite is a devilish variant.
Puzzle #17: Poisoning Zombies
Zombies have taken over the world, and also you preside over a stronghold with a gaggle of people attempting to construct a traditional life. You’ve gotten 1,000 barrels of water to hydrate your folks, however your chief scientist involves you one morning with some disturbing information: there’s been a contamination of the water provide, and one of many 1,000 barrels is now toxic, however he misplaced observe of which one.
The poisoned water seems and tastes like the entire others, but when anybody drinks even a drop, then they may all of the sudden fall useless that midnight.

Puzzle #17b
Right here’s a bonus puzzle: What’s the fewest variety of zombies you would want when you had 2,000 barrels and two days to run exams?
Neither drawback is simple, however the second is way more durable to conceptualize, and I don’t suggest attempting it till you’ve solved the primary one.

As a result of figuring out the variety of zombies you’ll want isn’t actually the puzzle, however relatively how you’ll use them.
So if it helps, for 1,000 barrels in someday you’ll want this many zombies. For two,000 barrels in two days, you’ll want this many zombies.
As a reminder, we encourage open dialogue and collaboration within the feedback, however this implies you would possibly encounter undesirable spoilers there. We are going to put up the answer and a brand new puzzle subsequent Monday. Good luck and blissful Halloween.
