The Eiffel Tower Grows Taller in Summer Heat

Original: 🗼 The Eiffel Tower grows taller in summer. Built from ~7,300 tonnes of iron, it expands in the heat — gaining up to 15 c

The Eiffel Tower, built from roughly 7,300 tonnes of iron, expands in warm weather and can gain up to 15 centimetres in height during summer before shrinking back as temperatures fall. On cold, windy days the entire structure can also sway slightly. The fact is being shared as a popular example of thermal expansion in engineering and physics.

Why now: A striking science fact about a famous landmark, shared as engaging physics content.
