I need to do work, but I don't know what to write. I can't use Wikipedia, because that's forbidden. I can't really use any website that's the first result on Google, unless it's very scientific-y and stuff... I can use my textbook, and I will for listing the effects of ash clouds, but it doesn't give a description. I'm going to use BBC News for describing what happened during the Eyjafjallajokull eruption. Hmm...
