How to Make a Clay Volcano

Did you know that there are around 1,510 active volcanoes in the world, and we currently know that more than 80 of these are under the sea! Volcanoes act like pressure valves, when too much pressure builds below the Earth's crust it is released in the form of magma and lava. Why not have a go at replicating your own mini volcanic eruption with this clay volcano, which uses a chemical reaction between bicarbonate of soda and white vinegar to produce foam, you could even add a few drops of food colouring to give the foam a splash of colour.
