Blow up a balloon using just bicarbonate of soda and vinegar in this simple science experiment

You will need

● Clear bottle
● Vinegar
● Balloon
● Bicarbonate of soda
● Funnel 

The Experiment

1. Pour 4 tablespoons of vinegar into the bottle. 2. Use the funnel to add 1 tablespoon of bicarbonate of soda into the balloon. 3. Pull the neck of the balloon over the neck of the bottle without releasing any bicarbonate of soda. 4. Lift the balloon so that the bicarbonate of soda falls from the balloon into the bottle and mixes with the vinegar. 5. Watch the balloon inflate on its own.  

The Science 

The bicarbonate of soda and vinegar react together to make an acid-base chemical reaction which produces carbon dioxide gas. Once the carbon dioxide fills the bottle it expands into the balloon, causing it to inflate.
