🧠 The Daily Fact #18

The Eiffel Tower grows taller in the summer. When temperatures rise, the iron expands, making the tower up to 12 centimeters (nearly 5 inches) taller. This phenomenon, known as thermal expansion, occurs because heat causes the particles in iron to vibrate and spread out. Similarly, in colder months, the tower shrinks back to its original size. Engineers accounted for this effect when designing the structure, ensuring that the slight seasonal shifts wouldn’t affect its stability. So next time you see the Eiffel Tower basking in the summer sun, know it’s literally stretching to reach new heights.
