I had a fabulous time at the Storylines Family Day in Auckland on Sunday (27th August). We set up four volcanoes in a row. I poured in vinegar and baking soda into two of them to give frothy demonstrations of volcanic eruptions. Quite a few kids were going to go home and try it (good luck, parents!). My hands were covered in red dye by the time I went home.
After the demonstrations, I encouraged children to make paper volcanoes with me. If you want to make one, go to the Eruption! book site on my website and you can download a Rangitoto activity. Colour it in, cut it out then glue the tabs together. You will then have your genuine own Rangitoto volcano.
