The allure of old buildings lies not only in their physical structures but also in the historical tales they hold. While the phrase “If these walls could talk” may be a bit cliché, it sparks the imagination to envision the lives and stories embedded within those timeworn walls. As a child, I was captivated by the charm of my grandparents’ 18th-century mansion, a dwelling that had exchanged hands multiple times over the centuries.
Contemplating the lives of those who inhabited the house in the 1800s and visualizing the landscape before its construction fueled my curiosity. It’s intriguing how many individuals remain oblivious to the secrets concealed within their own homes. A similar sense of astonishment struck Simon Marks from Luton, England, when he unwittingly stumbled upon a hidden piece of history in his front yard.

Several years ago, Simon Marks discovered an unexpected feature beneath his property: a two-roomed World War II air raid shelter. The incident unfolded as Simon drove into what he initially believed to be a flowerbed, only to realize that his vehicle had descended into the concealed structure. “A large hole developed. I thought it was a sinkhole or a badly constructed garden”, recounted Simon, 37, to The Sun.
Fearful that his entire house might disappear into the unexpected void, Simon investigated further. To his surprise, he uncovered a ladder and, upon using a selfie stick to peer into the depths, identified the underground relic as a World War II air raid shelter. His father, upon seeing the images, immediately recognized the structure and informed Simon of its historical significance.

Acquiring the home from an elderly couple who had constructed it in the 1970s, Simon speculated that the previous owners must have been aware of the shelter’s existence. “The previous owner must have known it was there, and when he built the house and put a garden in, he must have filled it in”, Simon surmised. Undeterred by the unexpected discovery, he expressed a keen interest in preserving and restoring the bunker, considering it a remarkable piece of history.
Motivated by their newfound historical treasure, Simon and his father embarked on a venture to uncover the entire two-room construction, digging with buckets to reveal the structure in its entirety. The process, captured in a video showcasing the shelter and its restoration, serves as a testament to the unexpected historical gems hidden beneath the surface of our everyday lives.
What number should replace the question mark
Cognitive puzzles have always intrigued and challenged our minds, pushing us to think outside the box. Today, we have an interesting brain teaser featuring fried eggs with an unknown number in one corner. The big question is: What number should replace the question mark?
At first glance, this puzzle might seem straightforward, but many people struggle to find the correct answer. Let’s break it down step by step, analyze common mistakes, and finally arrive at the right solution.
Try to Solve It First!

Before we dive into the solution, take a moment to analyze the image. Each fried egg pair or grouping has a number next to it, except for the last one. Your challenge is to figure out the pattern behind these numbers and determine the missing value.
So, what’s your answer? 12? 24? Something else? Let’s see if you’re right.
Common Mistakes People Make
Puzzles like this often trick people into seeing patterns that don’t actually exist or missing key details. Here are some common mistakes:
- Assuming the numbers represent the total number of yolks
Many people assume the number is simply the count of yolks in each grouping. However, if that were the case, the values would be 2, 3, 2, and 3—this doesn’t match the numbers given. - Thinking the numbers count the number of egg whites
Some might assume the numbers are based on the number of egg whites. However, we see cases where eggs are overlapping, making this unreliable. - Overcomplicating the pattern
Some puzzle solvers jump straight to complex mathematical operations before checking simpler patterns.
If you made one of these mistakes—don’t worry! Now let’s walk through the correct method to solve this.

Step-by-Step Solution: Finding the Pattern
Let’s examine the numbers given: 12, 23, and 22. Each number corresponds to a different grouping of eggs. But what do they mean?
Step 1: Count the Yolk Pairs and Their Positioning
Looking closely at each plate, we see that:
- 12 → Two yolks in one egg white.
- 23 → Three yolks in one egg white + two yolks in another egg white.
- 22 → Two yolks in each of two egg whites.
From this, we see that the numbers are NOT just counting yolks or egg whites alone.
Step 2: Understanding the Number Formation
Observing the pattern, the first digit of the number corresponds to the number of yolks in the first egg, and the second digit corresponds to the number of yolks in the second egg.
- 12 → (1 yolk in the first egg, 2 yolks in the second egg)
- 23 → (2 yolks in the first egg, 3 yolks in the second egg)
- 22 → (2 yolks in the first egg, 2 yolks in the second egg)
Step 3: Identifying the Last Number
Now, let’s apply this pattern to the final grouping, which contains 3 yolks in one egg white and no additional egg.
Following the same rule, the first digit is 3 (yolks in the first egg), and since there is no second egg, we assume the second digit is 1.
Thus, the missing number should be 13.
Final Answer: 13
After carefully analyzing the pattern, we conclude that the correct number to replace the question mark is 13. The first digit represents the number of yolks in the first egg, and the second digit represents the number of yolks in the second egg.
Did you get it right? If not, don’t worry! The key takeaway is to pay attention to patterns rather than just counting random elements.
