The children were very excited when as part of our Geography topic on Volcanoes we made a ‘volcanic eruption’. We used white vinegar, baking soda, red food colouring, washing up liquid and water to create our ‘eruption’. This also linked with science as we made a chemical reaction! Mixing the vinegar (acid) and the baking soda (alkali) releases bubbles of Carbon Dioxide (CO2). The washing up liquid is just there to trap the bubbles so it flows over the ‘volcano’ like real lava!
