Logic puzzles are always a great way to test our problem-solving skills and attention to detail. The image above presents a deceptively simple challenge: out of the seven cups shown, which one will fill up first? At first glance, it might seem like an easy question, but if you’re not careful, you might end up with the wrong answer. Ready to take on the challenge?

Why This Puzzle Tricks So Many People
At first, most people glance at the image and rush to answer. They might choose the cup closest to the teapot or the one that appears to have the shortest path. However, this puzzle isn’t as straightforward as it seems.
One of the most common mistakes people make is ignoring the blocked paths. The diagram cleverly includes sections where pipes are blocked or sealed, preventing water from flowing to certain cups. If you don’t pay close attention to these details, you’re likely to pick the wrong cup.
Another mistake is assuming that all paths are open and functional. Our brains are wired to think in terms of simplicity and efficiency, which often leads to us overlooking small barriers or obstructions in a puzzle like this.
The takeaway? Details matter. To solve puzzles like this, slowing down and carefully analyzing each component is crucial.
Step-by-Step Guide to Solving the Puzzle
Let’s solve this puzzle together. Grab a cup of tea (or coffee) and focus on the diagram. We’ll analyze the flow of water step by step.
- Start from the Source
The teapot is pouring water into the topmost pipe. From here, the water will naturally follow gravity, flowing down into the first available path. But not all paths are open. - Follow the Flow
The water flows down the central pipe and begins to branch out toward different cups. However, not all cups will receive water because some pathways are blocked. - Analyze the First Branch
As the water moves downward, it reaches the first branching point. This branch splits into two directions:- To the left, it leads toward cup 5.
- To the right, it leads toward cups 4 and 6.
- Check the Right Branch
Moving to the right, the water encounters two more pathways:- One path leads to cup 4, but it is also blocked at the base, preventing water from reaching the cup.
- The second path leads directly to cup 6.
- Confirm the Flow
Once the water reaches cup 6, it will fill up. No other cup can intercept the water because all other paths are blocked.
The Final Answer: Cup 6

So, the correct answer to this puzzle is cup 6. It’s the only cup with an unobstructed path for the water to flow into. Cups 4 and 5, despite being closer in appearance, are blocked and cannot fill up first.
Why Puzzles Like This Are Great for Your Brain
Puzzles like this aren’t just fun—they’re also an excellent way to sharpen your problem-solving skills and boost your logical thinking. Here are a few benefits of tackling logic puzzles:
- Improved attention to detail: Small details often make the biggest difference, as seen in this puzzle.

What those numbers on fruit stickers really mean
When it comes to groceries, we usually pay attention to the brand and the expiry date, but when it comes to fruits and vegetables most of us pick the ripe ones that look appealing to the eye. The truth is that fruits and vegetables are also labeled, but not many pay attention to those numbers mostly because they don’t even know what they stand for.
Numbers on fruit stickers like 9
Numbers on fruits serve more than the single purpose of identify how much the item should ring up. In fact, they provide valuable information about the product. If you notice fruit stickers starting with the numbers 9, out of five digits, it indicates that the fruit has been grown organically.

Number 8
If the five-digit number the fruit is labeled with starts with the number 8, it means the product has been genetically modified. GMO foods are controversial as many believe they cause and trigger allergies. This technology is often used in agriculture to enhance the resistance of crops to pests and diseases, improve tolerance to herbicides, or increase nutritional content.
Currently, researchers still investigate the long-term effects, if any, on humans. Some of the most notable GMO fruits are papayas, apples, plums, strawberries, and grapes, among the rest.

4-digit code
A 4-digit code starting with either number 3 or 4 signifies the food isn’t organically grown. Instead, it has likely been “conventionally grown.” The meaning of conventionally grown food refers to the way they are fertilized. While organic produce uses organic matter like compost and is mechanically or biologically treated for weeds, conventional methods use synthetic fertilizers and pesticides.

The debate about the environmental impacts and possible future health complications involving conventional food-growth methods is ongoing.
Dr. Tamika D. Sims, the senior director of food technology communications in Atlanta Georgia, says both organic and synthetic fertilizers have been “federally regulated.”

According to him, people shouldn’t worry about the numbers on fruits and vegetables they consume but rather focus on reaching a well-balanced diet with a variety of foods needed for good health.
When it comes to picking the right fruits and vegetables, the number of digits also matters. A 4 or 5-digit number indicates where and how the food was grown, in addition to the size and type of food purchased, but when the product is labeled with a sticker consisting of more than five digits, it means it’s not included in the “internationally standardized system.”

For most, going grocery shopping is a dull task they tend to complete as swiftly as possible.
However, knowing that the food we consume is crucial for our survival and maintaining our health and fitness, we should all pay more attention when choosing the food we purchase. The International Federation for Produce Standards is dedicated to “improving supply chain efficiency” which involves, among other responsibilities, ensuring the provision of high-quality ingredients and “establishing and unifying international standards.”

This system was first implemented during the 90’s, when stickers on fruits and vegetables were added. Categorizing these items with numerical codes was to guarantee high quality. The IFPS has issued more than 1,400 such codes. However, since the system is optional, not all fruits and vegetables in stores have been inspected or approved by the IFPS or meet global standards.
Those people who care of the choice of food they consume can find the knowledge behind the meaning of numbers on fruits and vegetables useful. This knowledge can also expedite the self-checkout process by simply entering the PLU code instead of searching for the item by name. The PLU code system is an excellent method to track the delicious and nutritious foods that travel worldwide.
