Baking Soda Volcano

6 cups of flour
2 cups of salt
4 tablespoons cooking oil
2 tablespoons of baking soda
dishwashing detergent
food color
warm water
baking dish or pan

First, make the cone of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil and 2 cups warm water. The mixture should be smooth and firm. Add more warm water if needed.

Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape.

*Don’t cover the opening or drop dough in it.

Fill the bottle most of the way full with warm water and a bit of red food color.

Add 6 drops of detergent to the bottle contents.

Add 2 tablespoons of baking soda to the contents.

Slowly pour vinegar into the bottle.

Watch the eruption!

Why does this happen? The red lava is the result of a chemical reaction between the baking soda and vinegar. In this reaction, the carbon dioxide gas is produced, pressure builds up inside the plastic bottle until the gas bubbles out of the volcano. This is a good representation of what happens in real volcanoes.
