    You can do about the eruption of volcano.


    -small drink bottle.

    -60ml water.

    -1 tablespoon baking soda.

    -1/4 cup vinegar.

    -orange food coloring .

    -few drops of dishwashing detergent.

    -small square of tissue.

    Making the eruption-

    Place the water, soap, food coluring and vinegar in the drink bottle.

    Wrap the baking soda in the tissue and drop into the bottle. The volcano will the then erupt

    The chemical reaction-

    NaHCO3 + CH3COOH --> Na + H2O + CO2 + CH3COO-

    Carbon dioxide is realized creating the fizz.

    For extra realism-

    The volcano can be made more realistic by enclosing the structure in a home made dough.

    Mix 6 cups of flour, 2 cups of flour, 4 tablespoons of cooking oil, and 2 cups of water in a large bowl.

    Mix the ingredients by hand until smooth and firm. Add more water to make the mixture if necessary.

    Build up the mixture around the drink bottle to create the mountain.

    Lava channels and vegetation can be built around the volcano.
