The city of Paris wanted to tear down the Eiffel Tower! Gustave Eiffel, an engineer and amateur scientist, had built the incredible structure for the 1889 World's Fair. Created using cutting-edge technology, it stood taller than any other building in the world! More than a million delighted people flocked to visit it during the fair. But the officials wondered, beyond being a spectacle, what is it good for? It must come down! But Eiffel loved his tower. He crafted a clever plan to make the tower too useful to tear down by turning it into "a laboratory such as science has never had at its disposal." As the date for the tower's demolition approached, Eiffel raced to prove its worth. Could science save the Eiffel Tower?.
