This was definitely one of the boys’ favorite experiments from our Fascinating Science for Kids eBook (that is currently FREE). We used up almost a whole bag of balloons and a whole bottle of vinegar doing this over and over and over again. I’m not complaining…I was equally as fascinated by this phenomenon!
Here’s what you’ll need: a 16 oz. bottle, vinegar, baking soda, a funnel and a balloon (actually several…your kids will want to do it repeatedly). :)
1. Use the funnel to pour 1/2 cup of white vinegar into the bottle. Rinse and dry the funnel.
2. Use the (clean and dry) funnel to put 1 tablespoons of baking soda into the bottom of the balloon. Shake gently to make sure all of the baking soda falls to the bottom.
3. Stretch the open end of the balloon over the neck of the bottle and make sure it is secured tightly. Let the rest of the balloon hang over the side (while you hold the bottle upright) so that no baking soda falls into the bottle just yet.
4. Hold onto the neck of the bottle (where the end of the balloon is) and carefully lift the heavier end of the balloon until you are holding it completely upright. All of the baking soda should fall into the bottle. The reaction will be immediate!
SO COOL!
The boys loved it so much, we had to try all the colors! :)
The Science Behind It:
When the baking soda and vinegar mix, it creates a chemical reaction. We know this because we see bubbles. This chemical reaction gives off a gas which inflates the balloon.

When you repeated your experiments did you have to clean it out first or were you able to reuse the vinegar solution?
Yes, you’ll need to dump the old solution out and rinse the bottle before repeating. :)
That looks like so much fun and is so easy. I’ll try with my grandsons when they visit this summer! Thanks, Renee
