Make a solid volcano with the mould and plaster provided. Paint and decorate your volcano with lava flow, landscapes etc. Put baking soda and vinegar into the "crater" and perform an amazing eruption in front of your friends and family. Your volcano will erupt with bubbly, fizzy lava. It's an awesome science project and it makes a cool desktop decoration too. The eruption can be performed repeatedly. Contains volcano mould (2 parts), 2 packages of fine quality plaster, a paint strip, brush, stirring tool, fun graphic boards for decoration, a volcanic scene, baking soda & detailed instructions. (Vinegar required, not included.) When constructed, the volcano is approximately 9.5 cm tall. Ages 8+.
