During the summer months, the Eiffel Tower gets a little taller. The thermal expansion generated by exposure to the summer sun can cause the Eiffel Tower to increase in height by as much as 6.75 inches (17 cm). This change is only temporary, and as the sunlight begins to fade, the expansion decreases. http://www.wisegeek.com/does-the-height-of-the-eiffel-tower-change.htmhttp://www.sciensational.com/physics.html
