Take a close look at the image. To figure out which cup fills first, we need to follow the liquid’s path through the pipes. Spoiler alert: not all cups are in play!
Here’s what we find:
- Cup 1: Blocked. No liquid gets through.
- Cup 2: Same deal—blocked.
- Cup 4: Also blocked.
- Cups 5, 6, and 7: Located farther down the system with long or obstructed paths, meaning they’ll take much longer (if they fill at all).
That leaves Cup 3, the only one with a clear and open path. Liquid flows straight there, making it the first to fill.
Final Answer: Cup 3. Now, go impress your friends with your puzzle-solving skills!
