Give young children a magic show and you’ll be their new Hero. They will love you not for a minute but for days and weeks. You’ll be their story to the parents and all who will listen. Their concrete thinking brain will be amazed when they see how a balloon blows up without someone/thing blowing air inside. They will ask you to repeat this experiment for days. It’s up to you if you want to talk to them about the chemical reaction that takes place. Regardless of how you go about this activity – I guarantee they will be blown away.
Each child gets a turn filling the balloons with baking soda. We used a funnel to help.
The baking soda balloon is added to the bottle containing the vinegar. Put the balloon on at an angle, so the baking soda doesn’t spill or enters the bottle without being completely on the mouth area of the bottle.
When completely on the bottle lift balloon and shake – empty in the bottle and …..wait for it … tadahhhhh
Repeat as many times as they ask for it because it will continue to amaze them. I have repeated this project many times over with the same kids and different sets. They never get bored seeing the balloon rise from the carbon dioxide. Carbon dioxide is formed when the vinegar and bicarbonate (baking soda) reacts with each other.
