Eiffel Tower's Summer Growth Spurt

That's correct! The Eiffel Tower, made primarily of iron, can indeed expand in height during the hot summer months due to the thermal expansion of iron. When exposed to high temperatures, iron atoms absorb heat energy and vibrate more, causing the iron structure to expand. This expansion can make the Eiffel Tower up to 15 centimeters taller than its usual height during the summer. It's a fascinating example of how materials can respond to changes in temperature.
