How to Make Lava Goo for a Project

Create lava goo for a more realistic eruption.

Making a volcano erupt is a common science project for children. However, the eruption does not have to be the predictable foam-and-fizzle lava made from baking soda and vinegar. Children can create lava goo that has a more realistic look than the traditional recipe. Not only will the lava goo be fun for kids to make, but they can also impress their teacher and classmates with the goo as it makes it way down the volcano.

    Cover the work surface with newspaper. Ideally, do this project outside to avoid having a huge mess to clean up later.

    Mix together the glue and water in a container. Use one part glue to one part water; the exact amount depends on how much lava goo you need for the project.

    Stir in the Borax 1 tablespoon at a time until the mixture becomes a gooey substance that holds together.

    Add a few drops of food coloring to the container.

    Add 4 tablespoons of baking soda to the mixture.

    Pour in 1 cup of vinegar when you're ready to create the eruption. Watch as the baking soda and vinegar begin to foam. As it rises to the top of the container, the goo will as well.
