Fun Fact Friday

I am fascinated by interesting world facts... I set myself funny little challenges from time like learning the names of every country in the world or the population of every country in the world, or all the capital cities of the world. I'm not sure if I'm OCD or boring - either way, I really enjoy it. And it's good exercise for my photographic memory.

So, I have set myself a new challenge: to learn a new world fact every Friday and share it here - Fun Fact Friday! (I'm thinking a jingle in my head, it goes like this: Fun Fact Friday-der-der-der-der-der Fun Fact Friday!)

And here is today's fun fact:

The tallest building in America is the Willis Tower in Chicago. It has 108 floors and is 442 metres high. It has been used in lots of films, usually with someone falling or jumping off the top of it: Batman the Dark Knight and the new transformers film.

It was the tallest building in the world until 1998 when it was overtaken by the Petronas Twin Towers in Kuala Lumpur (both 452 metres tall).

The tallest building in the world, as at 2010, at almost twice the height of Willis Tower is Burj Khalifa in Dubai (828 metres, 163 floors).
