A clever video puzzle to keep your brain active on a Friday. You’re a wizard and you’re making a potion. It needs to be stirred after exactly 45 minutes, no earlier and no later, or else it will be ruined. You have no clock or timer, but you do have two fuses of irregular consistency, each of which takes one hour to burn from one end to the other. How do you know when to stir your potion? Pause the video at the 4:30 mark if you don’t want to hear the answer.
I have to admit that a lifetime of listening to National Public Radio’s Car Talk program, with its weekly “Puzzler” segment, had me well prepared to figure this out. How did you do?
5 Thoughts on "Friday Potion Puzzler"
mark the fuse into quarters and stir the potion when 3/4 have burned. My guess.
I hate to admit it, but I don’t quite get the explanation. (But I won’t go into it here because spoilers.)
Nailed it! Or, well, burned it!
You can’t rely on the fuses, but if I’m a wizard I’d be used to mixing potions and would rely on my intuition for knowing when to stir? 🙂
