1. The Eiffel Tower Can Be 15 cm Taller in Summer
Did you know that the iconic Eiffel Tower can actually grow taller? Due to thermal expansion, when the temperature rises, the metal expands, causing the tower to increase in height by approximately 15 centimeters (6 inches).
2. Bananas Are Berries, but Strawberries Aren’t
In botanical terms, a berry is defined as a fruit produced from the ovary of a single flower with seeds embedded in the flesh. Under this definition, bananas qualify as berries, while strawberries do not!
3. Hummingbirds Are the Only Birds That Can Fly Backward
Hummingbirds are unique not just for their rapid wing beats but also for their ability to fly backward! This impressive feat is made possible by their flexible shoulder joints, allowing them to maneuver in ways most other birds cannot.
4. A Day on Venus Is Longer Than a Year
Venus has an extremely slow rotation period, taking about 243 Earth days to complete one day. However, it orbits the sun in about 225 Earth days, making a day on Venus longer than its year!
5. Humans Share 60% of Their DNA with Bananas
While we certainly differ from bananas in many ways, our DNA is surprisingly similar. Studies have shown that humans share approximately 60% of their DNA with these vibrant fruits, reminding us of the interconnectedness of life across species.
6. Octopuses Have Three Hearts
Octopuses are fascinating creatures—not only do they have eight arms, but they also possess three hearts! Two pump blood to the gills, while one pumps it to the rest of the body. Intriguingly, the heart that delivers blood to the body stops beating when the octopus swims, which is why they prefer crawling.
7. The Shortest War in History Lasted Only 38 Minutes

8. Honey Never Spoils
Archaeologists have discovered pots of honey that are over 3,000 years old and still perfectly edible! Honey’s low moisture content and acidic nature create an inhospitable environment for bacteria and mold, allowing it to last indefinitely.
9. The Electric Chair Was Invented by a Dentist
The electric chair, a method of execution in the United States, was developed in the late 19th century by Dr. Alfred Southwick, a dentist who believed it to be a more humane alternative to hanging.
