Demonstrating acid-base reactions, fluorescence and chemiluminescence
The tornado effect can be used to demonstrate several chemical concepts to 14–16-year olds. Here we describe a few experiments that you might use to liven up what might otherwise be uninspiring lessons on: acid-base indicators; fluorescence; chemiluminescence; and precipitation reactions. The chemical tornado can also be used if you are teaching younger pupils about the mixing of primary colours by using supermarket food colourings.
