Jaiden and Kaiden learn how much air is in a bottle of soda! This carbonation experiment combines their love for balloons and the fascination with the fizzy bubbles. With just a few supplies and a few steps, you can blow up a balloon with carbon dioxide bubbles. For even more carbonation fun, they tried it with variations of salt, mentos candy, and baking soda. When these ingredients were mixed, which combination do you think had the biggest reaction?
