3. Plastic bottle
All our measurements were estimations only.
|Pour some vinegar into the bottle|
|Pour 2 - 3 spoonfuls of baking soda into the balloon|
|Place the balloon onto the mouth of the bottle, and hold up balloon so that the baking soda falls down into the vinegar below. This creates gas.|
|The solution starts bubbling and creates gas which inflates the balloon.|
