Walking on eggshells in chemistry

It's Royal Society of Chemistry podcast time again. The subject today has me seeing double and walking on eggshells. No really, I know it's true because it says so on the RSC website.

Today's subject is calcium carbonate. This may be a pretty common mineral, but it more than makes up with it thanks to some clever tricks. As Paul Daniels used to say, when it comes to clever tricks, 'You'll like it. Not a lot.' But what did he know? This isn't boring old magic, it's chemistry. Take a listen. Take a listen. Now I'm typing double as well.
