I brought along the necessary equipment to make a 'Fizz Inflator'. It was even better than I had expected. Bicarb+vinegar+kids reactions never gets tired!
Mel brought her volcano for more bicarb and vinegar fun. She also had a cool experiment using red cabbage water as an acid and alkaline indicator. I think we'll do this again at home.
On the way home we saw four swans flying through the sky. They looked awesome!
