Make a volcano

What do you need?

- bicarbonate of soda
- vinegar
- red food colouring

- cardboard to form into a cone
- glue and ashes or dirt, to make it look real
- a small bottle to place inside the cone

Method:

Make your volcano then place a spoonful of bicarbonate of soda, and a teaspoon of red food colouring in the bottle.

Pour some vinegar into the bottle and stand back!

- The cool red lava is the result of a chemical reaction between the baking soda and vinegar.

- In this reaction, carbon dioxide gas is produced, which is also present in real volcanos.

- As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until the gas bubbles out of the 'volcano'.
