Title: Volcano
Goal: How to make a Volcano.
Materials: bottle, shoebox, tinfoil, red food colouring, bread soda (sodium bicarbonate), malt vinegar (acid)
Steps: 
1. Put the bottle in the shoebox and cover with tinfoil. 
2. Place 1/4 of red food colouring into the bottle. 
3. Add 5 small spoons of bread soda to the bottle. 
4. Pour vinegar into the bottle until it foams up. 
-the sodium bicarbonate in the bread soda reacted with the acid in the vinegar and cause the Volcano erupt.
