Materials: a cookie sheet, 1/4 cup vinegar, 2 tablespoons baking soda, red food coloring, 12 oz. plastic water bottle, funnel, a bowl, 3 cups flour, 1 cup salt, 1 cup water, 2 tablespoons vegetable oil, a syringe
Instructions: Make the inside of the volcano. Pour the baking soda into the plastic water bottle. Set that in the middle of the cookie sheet.
In a cup mix the vinegar and red food coloring and set aside.
Make the outside of the volcano. In a large bowl, mix the flour, salt, water, and vegetable oil. Once it's mixed and thick, use it to sculpt your volcano around your plastic bottle on your cookie sheet.
Let the outside set and get hard. You can paint it, go outside and get some grass to add to the base of your volcano.

Use your syringe to pull up your red vinegar and push it into the top of your volcano as fast as you can to watch the eruption!
