Here’s another video that might come in useful when teaching about acids and alkalis – Rosie Coates shows us her favourite chemistry demonstration involving a giant test-tube and some universal indicator solution. As well as showing us a fantastic demo, Rosie explains how the science of acids and alkalis can have important real-world applications.

This is another video where it’s really worth hitting the “HQ” button on the youtube player after you’ve hit “play”.
