What better science experiment to do when discussing the earth’s atmosphere than the classic baking soda vinegar experiment? This idea I credit to my middle son. I bought adorable earth balloons and stashed them away in my secret science shelves (also known as “my pantry”). My second born discovered these balloons and probably thanks to some youtube video begged to have access to the baking soda and vinegar. My sons cannot get enough of science. We are a lab on most days experimenting with various substances and reactions.
How could a mom resist? Really?
Seriously, look at that face? Such awe. I can’t resist.

- Gather your materials
- Place the balloon opening around the opening of the funnel
- Pour baking soda into the funnel to fill the balloon half way or so
- Use the funnel to fill the plastic bottle with a good amount of vinegar
- Place the balloon opening around the mouth of the bottle
- Hold the balloon up so the baking soda falls into the bottle
Science Behind Baking Soda Vinegar Chemistry
The baking soda and the vinegar have chemistry. When the baking soda meets the vinegar, carbon dioxide is created and fills the balloon causing it to inflate. Carbon dioxide is an important gas in the earth’s atmosphere. Carbon Dioxide plays a vital role in regulating the earth’s temperature. Baking soda and vinegar have an acid based reaction, which results in the gas that fills the balloon.
