Build a Fizz Inflator

Take a of our masterclass experiment and upload to your learning journal. Add a to explain the science involved in this experiment. You will need One small empty plastic soda or water bottle 1/2 cup of vinegar Small balloon Baking soda Funnel or piece of paper What to do Carefully pour the vinegar into the bottle. This is the tricky part: Loosen up the balloon by stretching it a few times and then use the funnel to fill it a bit more than half way with baking soda. If you don’t have a funnel you can make one using the paper and some tape. Now carefully put the neck of the balloon all the way over the neck of the bottle without letting any baking soda into the bottle. Ready? Lift the balloon up so that the baking soda falls from the balloon into the bottle and mixes with the vinegar. Watch the fizz-inflator at work!
