Do you know the formula for mixing vinegar and baking soda to make a simulated volcanic eruption? We found a kit in the store, but we want to do it ourselves. thanks

John,

I'm not sure there is a formula! Experiment by pouring a little vinegar in, and repeat adding more until you make the best eruption. Too little, and you will have unfizzed baking soda, too much and it's all over too quickly. Add some red food coloring too, to make your lava flows look hot! Happy erupting!
