One of the first experiments during the Science Week at Babelis was inflating the balloon in a different way.
1/2 cup vinegar
4 tablespoons of baking soda
and a balloon
First, we poured the vinegar into the bottle and we filled the balloon with baking soda. Next, we put the balloon on top of the bottle and let the baking soda fall into vinegar to begin the chemical reaction. To our great surprise, the balloon started growing and growing!!!
We made it!!!
Check the kids faces and you will see if they enjoyed it or not 🙂
