Today our science experiment was all about Fizz Balloons.
•a plastic bottle
1. Pour 3 to 5cm of vinegar into a plastic bottle.
2. Use a funnel and add about 2 tablespoons of baking soda to the vinegar.
3.Quickly place the neck of the balloon over the end of the bottle.
4. Watch wha happens.
Why is this happening:
Baking soda is a substance called a base. Vinegar is a substance called an acid. When bases and acids combine they create new substance. In this experiment carbon dioxide is created. Carbon dioxide is a gas; the gas leaves the bottle and blows up the balloon.
Here is our video to show you.
