Next we carefully put 2 tablespoons of baking soda into the balloon. We fitted the balloon over the neck of the bottle and tied it on with string. Then we lifted the ballon straight and the baking soda fell into the vinegar. Straight away the balloon went up.
We filled our plastic drink bottle one third full of vinegar.
First we tested what happened when you added baking soda to vinegar.
