This is how we made our baking soda and vinegar volcano. We used lego to build the volcano but you can use anything that looks like a mountain. This is a messy project, you will want to make sure the area is contained. Especially if you use any food coloring. And especially if you use lego for volcano. Apparently lego does not make a very air tight container and will have lots of leakage.
