Make a solid volcano with the mould and plaster provided. Paint and decorate it with lava flow, landscapes etc. Put in baking soda and vinegar into the crater and perform an amazing eruption in front of your friends and family. Your very own volcano will really erupt with bubbly, fizzy lava. It's an awesome science project and it makes a cool desk-top decoration too. The eruption could perform repeatedly and the fun is unlimited. Contains 1 volcano mould (2 parts), 2 fine quality plaster mix, 1 paint strip of 6 colours, 1 brush, 1 stirrer, 1 fun graphic boards for decoration, 1 moulding and painting instructions with volcanic scene, fun facts and recipe for eruption. (Baking soda and vinegar are required to perform the eruption. Not included in this kit) A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot, molten rock, ash, and gases to escape from below the surface. Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a period of time.
