Nothing like a bit of exploding fun to get kids interested in science! The beauty of this kit is that you make and build everything yourself. So to begin you need make your volcano using the plaster powder and special mould. Then, using the paints provided, add colour, texture and lava flows to make your volcano as realistic as possible. Then finally you can learn how to make your volcano erupt using baking soda and vinegar. And with this model eruptions can be made over and over again!
