To make an erupting volcano you will need:

A volcano - Talk to an art teacher about making a volcano out of paper mache or plaster. If you're in a hurry to make your volcano, use a mound of dirt outside.

Red and yellow food colouring (optional)

Vinegar

Liquid dish washing soap

What to do:

Go outside

Add two spoonfuls of baking soda

Add about a spoonful of soap

Add about 3 drops of the red and yellow food colouring

Now for the eruption!:

Add about an ounce of the vinegar into the container and watch what happens.

The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:

1. Does vinegar temperature affect how the volcano erupts?

2. Does the shape of the volcano affect the direction the eruption travels?

3. What home design protects it from lava the best? (build small model homes to test this)

4. What can be added to the "lava" to slow it down and make it more realistic?

5. What combination of vinegar and baking soda creates the biggest eruption?
