Hi Sara, Thanks for your question. This resource is part of our Microscale chemistry collection. The resources originally appeared in the book Microscale chemistry: experiments in miniature, edited by John Skinner and published by the Royal Society of Chemistry in 1998. The ideas behind the experiments in the book come from many sources, including chemistry teachers from all around the world. Please do comment or email us (check edu.rsc.org/contact-us for our email address) if you have any other questions we can help with.
