Question

The next step in building your model volcano is to make a paper cone around the plastic bottle to represent the outside of the volcano. Decorate it to look like a mountain. Add the baking soda and water to the bottle, and use a pipette to stir. In a separate cup, mix the vinegar and food coloring. Obviously, red would be the best choice for lava but use any color you wish. Very slowly add the vinegar mixture to the bottle. Now watch the lava flow!
