A spot of the blue stuff

Just when you thought it was safe to take out your earplugs, we have another of the Royal Society of Chemistry podcasts. This time it's about a compound that is familiar from many a chemistry set - copper sulphate (or copper sulfate as the PC police require us to call it). This brilliant blue substance (at least in its hydrated form - pure copper sulfate is practically white) finds its way into a wide range of places from agriculture and book binding to the arts, where it has the honour of taking part in one of the few Turner Prize shortlisted artworks that the general public can actually enjoy. So come on - succumb to blue. You know you want to: take a listen.
