Baking Soda Volcano (Creative Chemistry Experiments)

You will need:

1. 6 cups of flour
2. 2 cups of salt
3. 4 tablespoonfuls of
   cooking oil
4. Warm water
5. Plastic bottle
6. Liquid soap
7. Red or orange food colour
8. Vinegar
9. Large pan or dish
10. 2 tablespoonfuls of
    baking soda

A baking soda volcano is the homemade kitchen version of a volcano. It is obviously not the actual thing, but you could create and have fun replicating the same explosive reaction of a volcano by yourself.

INSTRUCTIONS

1. Firstly, create your volcanic mountain. Take flour, salt, cooking oil and 2 cups of water and make dough out of this mixture, which will be firm but easily mouldable.
2. Place an empty plastic bottle in a large pan or dish. Mould the dough into a hill around the bottle, taking care that no dough falls into the bottle.
3. Colour the mould to resemble a hill.
4. Pour warm water into the bottle filling
   it three-fourths of the way, and add a few drops of liquid soap.
5. Add baking soda to the water.
6. Mix red/orange food colour into the vinegar and slowly pour the red-coloured vinegar into the bottle.

RESULT

The vinegar will react with the baking soda and create carbon dioxide, which builds up and creates lava-like eruption.
