=**Have you ever seen a volcano erupt? Well, how about making your own? It's much safer! ** = ===**This is a messy experiment so ask mum or dad to help you and make sure you clean up after you have finished.** ===

** You will need: **

 * = flour =
 * = salt =
 * = water =
 * cooking oil
 * a large bowl
 * a clean plastic soda bottle
 * a baking pan
 * food colouring (red looks good)
 * liquid detergent
 * baking soda
 * vinegar


 * // Instructions //
 * 1) Mix 6 cups of flour, 2 cups of salt, 4 tablespoons of cooking oil and 2 cups of water in a large bowl.
 * 2) Using your hands, mix the ingredients until smooth and firm. Add more water to the mixture if needed.
 * 3) Stand the soda bottle in the baking pan.
 * 4) Mold the salt dough around the bottle. Make sure you don't cover up the bottle mouth or drop any dough in the bottle.
 * 5) Fill the bottle almost to the top with warm water.
 * 6) Add drops of food colouring until you get a colour you like.
 * 7) Squeeze 6 drops of the liquid detergent into the bottle.
 * 8) Add 2 tablespoons of baking soda.
 * 9) Slowly pour vinegar into the bottle and jump back quickly.
 * 10) What do you think will happen?


 * == What happens? ==

** The 'lava' flows out of your volcano! **

 * Why and how does this happen?


 * == A chemical reaction is where one substance is chemically changed to another. ==

==** The gas that is created by the chemical reaction builds up in the bottle and pushes the liquid 'lava' mixture up and over the mouth of your volcano. ** ==

FUN FACT! Volcanic eruptions can actually help us. Over time volcanic materials break down and become fertile soils which help plants and crops to grow.

Did you know that Banks Peninsula was once an active volcano?

Iceland has a famous volcano called __Eyjafjallajokull__, can you pronounce that???
