Create a Volcano
Use the diagram below.
Glue a plastic bottle onto a wooden base. Place the mountain-shaped chicken wire over the bottle and cover it with paper strips dipped in glue made by heating and stirring a flour and water mixture. After a couple of days when it is dry, paint it like a volcano (lots of streaks of red, yellow, brown and black). Place two teaspoons of sodium bicarbonate (also called baking soda), a few drops of red food colouring and lastly, some vinegar into the bottle. Watch your volcano erupt.
