Science Current Event

There’s science fair coming up and I have nothing to come up with. http://news.nationalgeographic.com/news/2009/03/photogalleries/create-the-future/photo4.html?source=email_gg_20090318&email=gg . Take a look. Some of those inventions are just so simple yet I’ve never even thought of them. Am I a stub? I’m smart and all but I haven’t the Ideas.
Help! Just state some daily problems and complain about why is it such a fuss. I need to know what needs do average people have.
Please post, this is an emergency! I came up with nothing last year. I really hope to do something this year!!!
Please write, I BEG YOU!
