Experiment from Kinga & Żaneta
We pour vinegar into a bottle and fill the balloon with baking soda. Then we're stretching a balloon on the bottle and turn it up side down. The balloon grows up by itself. In this experiment carbon dioxide is created.
Next we let it into the bottle. The burning match will dejeckt in this bottle, because there isn't any oxygen.
So when we remove the carbon dioxide from the bottle, the match will burn because there is oxygen inside now.
