Volcanoes


Here is a photo of the volcano we used in class to do an experiment. It's made of flour, water and salt and has a plastic bottle incorporated so that you can add liquids. We put some coloured water in the bottle, then added a few drops of washing up liquid and two tablespoons of bicarbonate of soda. Finally we added some vinegar. It really started to fizz and then erupted just like a real volcano! Why don't you try making one?
