Baking soda & vinegar. Maybe a little dry ice for extra effect. You can build the structure from paper machete or spray foam insulation. Experiment with different amounts of the vinegar and baking soda to get the volume and duration of eruption you require. If you also use the dry ice have it in water in a separate container from the vinegar & soda.
