How to make a volcano

This is a messy project and needs space, so if you can, make it outdoors or cover your work area with newspaper.

you will need: modelling clay (brown and red are best), baking soda, red food colouring, washing-up liquid, vinegar

1. Make a volcano shape with the modelling clay. Use brown clay for the base and red clay for rim to look like

hot lava. If you can't find red clay, colour a small amount with the food colouring.

2. Scoop out a hole in the top of the volcano for the crater.Put 1 tablespoon of baking soda, a few dropsof red food

colouring and a few drops of washing-up liquid in the crater.

3. pour in 1/4 cup of vinegar, stand well back and watch the volcano erupt.
