My grandson's first pH experiment

摘要

Yesterday, I had my grandson of four years help with the red cabbage experiment (June issue, p. 36) and he loved the colours and their intensity as the ice blocks melted. Sadly, I did not have any lemons but they can wait for another day. Brilliant stuff, and so by the time I reach my 50 RACI years in 2019 he will, I hope, be full of exploring the chemistry and beauty of the natural world with me.
