red cabbage experiment

It's amazing what you can do with the dye that colours the cabbage red - its a great pH indicator and is an ideal experiment for kids

With Alex yesterday we figured out bleach is very alkaline and lemon juice very acidic - i even got him to do a neutralisation experiment when it started to fizz he got very excited

Off to Coleby to get some work done on the heated electrode paper for the upcoming Faraday discussion
