Only a few people manage to spot all the faces hidden in this tree — are you one of them?
It’s been circulating online for years and continues to fascinate. Why? Because it forces us to slow down, to observe differently, and to question what we think we see. A bit like looking for your glasses when they’re already on your head.
Why do we all see a different number of faces?
Some people immediately spot several faces, while others struggle to distinguish more than two or three. And that’s perfectly normal. Our brains love to recognize familiar shapes, especially faces, but they do so differently in each person.
Our experience, our current level of attention, and even our mood influence what we perceive. One day, you might see seven. The next day, maybe ten. It’s not a test, simply an observation game that shows just how malleable our perception is.
How many faces did you find? To make the challenge even more fun, some internet users have come up with a playful interpretation of the results. Take this with a grain of salt, of course, like a horoscope for your eyes.
2 to 4 faces spotted
You’ve grasped the essentials, but your eye can still be trained. This type of game is ideal for gradually sharpening your attention, like a warm-up before sports.

5 to 6 faces spotted
Your sense of observation is already quite sharp. You know how to look beyond the obvious, even if there are still a few hidden details to uncover.
7 to 8 faces spotted
Well done! You observe with patience and precision. You like to explore details and not stop at first impressions.
9 or more faces spotted
Hats off! Your eye is particularly sharp. You spot subtleties where others miss them: a real talent for this type of visual challenge.

How to improve your observation skills every day
Good news: observation skills can be trained, a bit like a muscle. Optical illusions, visual puzzles, word searches, or simply moments of screen-free contemplation are excellent allies. Even carefully observing a familiar street can reveal unexpected details.
The goal isn’t to perform, but to have fun while stimulating your curiosity. A few minutes a day is enough to train your eye, like whipping egg whites: slowly but surely. A perfect game to share
This type of challenge also has a unifying power. With friends, family, or even colleagues, everyone compares their score, discusses, and defends what they saw. And often, someone ends up saying, “Yes, look there!”, revealing a face that no one had noticed.
So, ready to launch the challenge and see who has the sharpest eye?
Sometimes, all it takes is a simple tree and a little curiosity to transform a few ordinary minutes into a real moment of play and sharing.
If You Open a Watermelon and See This
If You Open a Watermelon and See This …Throw It Out
Cutting into a watermelon is usually a refreshing moment — bright red flesh, sweet aroma, and plenty of juice. But if you slice one open and notice foam bubbling or oozing from the inside, stop immediately and throw it away. This isn’t a harmless oddity. It’s a clear warning sign that the watermelon has begun to ferment and spoil, and eating it could be dangerous.
Why Foaming Watermelon Is a Red Flag
Watermelon is naturally high in sugar, which makes it especially vulnerable to bacteria and yeast. When these microorganisms infiltrate the fruit, they feed on the sugars and begin a fermentation process. As this happens, gases like carbon dioxide build up inside the melon.
Eventually, that pressure needs to escape. When it does, the gas mixes with liquid inside the fruit and pushes out as foam or bubbling liquid through cracks in the flesh or rind. Essentially, the watermelon has turned into a small fermentation chamber.
Food safety experts warn that consuming fermented watermelon may expose you to harmful pathogens such as E. coli, Salmonella, or, in rare but severe cases, toxins associated with botulism. The most dangerous part is that the spoilage often starts internally, meaning the rind can look perfectly normal while the inside is already unsafe.
Other Signs Your Watermelon Has Gone Bad
Foam is one of the most obvious indicators, but it’s not the only one. Watch for these warning signs:
Sour or unpleasant smell: Fresh watermelon should smell lightly sweet, never sharp or acidic.
Slimy or mushy texture: Flesh that feels slippery or overly soft is breaking down.
Fizzy or tingling taste: A carbonated sensation points to active fermentation.
Dark or sunken spots: Discoloration or depressions inside the fruit often signal decay.
Cracks in the rind: These openings allow bacteria and air to enter, speeding spoilage.
If you notice any of these, it’s best to play it safe and discard the melon.
How Heat Makes Things Worse
Hot weather dramatically increases the risk of watermelon fermentation. Heat accelerates bacterial growth and metabolic activity, meaning spoilage can happen quickly — sometimes before there’s any visible external damage. In extreme cases, pressure buildup inside the melon can even cause it to crack or burst when you try to cut it.
To slow this process:
Store whole watermelons in a cool place or refrigerate when possible
Refrigerate cut watermelon immediately
Consume cut pieces within a few days
How to Protect Yourself
A few simple precautions can reduce your risk of spoiled fruit:
Inspect before cutting: Avoid melons with soft spots, cracks, or damp areas.
Wash the rind: Rinse thoroughly under running water before slicing to prevent contamination.
Use clean tools: Always cut with a clean knife on a clean surface.
Check after cutting: Look, smell, and sample a small piece before eating.
Refrigerate promptly: Store leftovers wrapped and chilled below 4°C (39°F).
Dispose safely: Seal spoiled melons in a bag before throwing them away to prevent leaks.
The Bottom Line
Foaming inside a watermelon is not something to ignore. It’s a sign that the fruit is actively breaking down and may contain harmful microbes. Even if some sections appear normal, once fermentation begins, the entire watermelon is unsafe. When it comes to food safety, it’s always better to throw it out than risk getting sick.
