Occasional Puzzles - 🐟 Fishy Fish
As much as we love elaborate puzzles involving poorly equipped kitchens and puzzle-obsessed friends, sometimes you just have to keep it simple.
Today's puzzle came about when our friend David decided to ask Gemini, Google's AI chatbot, to write us a riddle. After a few false starts, we were all excited when it gave us this pretty clever one! However, a quick search revealed that it was not actually written by Gemini and is, in fact, a well-known riddle.
That said, we enjoyed it and hope you do too!

I have cities, but no houses.
I have mountains, but no trees.
I have water, but no fish.
What am I?

Previous Puzzle - 🍪 Cookie Conundrum
Puzzle
You've recently discovered a new cookie recipe that you're dying to try. The author of the recipe is quite adamant that the cookies must bake for exactly nine minutes. Unfortunately, all you've got to measure time is two hourglasses: one that measures four minutes and one that measures seven minutes. (Is this the same kitchen that only has an old-fashioned balance? Maybe it's time to upgrade some kitchen equipment...)
With these two hourglasses, how do you measure precisely nine minutes?
Solution [SPOILER]
- Start both hourglasses simultaneously.
- When the four-minute hourglass is empty, flip it again. At this point, the seven-minute hourglass has three minutes left.
- When the seven-minute hourglass is empty, the four-minute hourglass has one minute left. Put the cookies in the oven. Your nine-minute timer begins now!
- When the four-minute hourglass is empty, one minute of your timer has elapsed. Flip the four-minute hourglass again.
- When the four-minute hourglass is empty again, the cookies have been in for five minutes total. Flip the four-minute hourglass one final time.
- When the four-minute hourglass is empty once again, it's been exactly nine minutes! Take the cookies out of the oven.
- Enjoy your perfectly baked cookies!
