I am currently working at BBC Radio 4 on Material World's 'So You Want To Be A Scientist?' We're still looking for more science ideas and big questions from non-scientist. So if there is something you've always wanted to know, send it in to the SYWTBAS webstite. If your idea makes it into the final, you'll be teamed up with a scientist who will help you design an experiment that could answer your question and you'll be doing the experiment yourself together with the scientist! For more info, see the SYWTBAS website.
