‘I did the lava lamp experiment. We found some effervescent tablets but Mum thinks they were out of date as they did not fizz! ….but we found some Citric acid and that worked. We watched the bubbles break through the oil to the surface (unfortunately we could not use much oil as Mum did not have much left!)’

A really impressive experiment by Theo who has thought outside of the box in terms of materials to use in the experiment. Mrs Cullen
