This is an instructable on how to make your own small scale volcano.

Step 1: You Will Need :-

A volcano -You can use clay or if you're in a hurry to make your volcano, use a mound of dirt outside.

A container that 35mm film comes in or similar size container.

Red and yellow food coloring (optional)

Vinegar

Liquid dish washing soap

Step 2: Procedure:-

Go outside or prepare for some clean-up inside
Put the container into the volcano at the top
Add two spoonfuls of baking soda
Add about a spoonful of dish soap
Add about 5 drops each of the red and yellow food coloring

Now for the eruption!:
Add about an ounce of the vinegar into the container and watch what your volcano come alive.

Step 3: How Does It Work

A VOLCANO is produced over thousands of years as heat a pressure build up. That aspect of a volcano is very difficult to recreate in a home experiment. However this volcano will give you an idea of what it might look like when a volcano erupts flowing lava. This is a classic experiment in which a CHEMICAL reaction can create the appearance of a PHYSICAL volcano eruption. You should look at pictures of volcanoes to be familiar with the different types. (A SHIELD volcano, for example is the most common kind of volcano, and yet few people know about them) The reaction will bubble up and flow down the side like a real volcano (only much faster!) Look for videos of volcanoes erupting and be sure that you understand how heat and pressure work to really make volcanoes erupt.
