The Baking Soda and Vinegar Experiment

Friday night Heidi, Shawn, and I attended a Science Event for the Girl Scouts in our area. There were about 80 girls in attendance broken into twelve or so smaller groups. Each group went from station to station participating in a science project. At the end of the event each girl made a magic wand out of a light bulb, a stick, some wire, and a battery. This project earned them a badge.

But the project that our family enjoyed the most involved a balloon, a 20 ounce bottle, some vinegar, and baking soda.

Heidi wanted to show Margie, Kristen, and Taylor this little experiment after dinner on Sunday night. She grabbed a Mellow Yellow bottle from the recycle, found a balloon in her craft station, and set up the experiment on the kitchen table.

We put some vinegar in the empty bottle, about ¼ a cup. Then we put about ½ a tablespoon of baking soda in the balloon. Stretch the top of the balloon over the bottle so it fits securely then lift the balloon allowing the baking soda to pour into the vinegar.

The mix of vinegar and baking soda cause gas which inflates the balloon. It’s pretty cool!

When the demonstration was over, Heidi took the balloon off the top and deflated it right in my face. Let me tell you the smell of latex and vinegar is gag inducing!

She cleaned up the table, the best a six year old is able, and we all went about our evening.

A few hours later, Shawn is in the kitchen when all of a sudden we hear:

“ACK! HAHAHA!! Ick!!”

Margie passes through the kitchen “What are you doing?!”

Shawn “I am washing my mouth out!!”

Heidi and I are in the living room, confused but laughing any way.

Me: What happened? What did you do?

Shawn: I found a delicious Mellow Yellow on the counter without a lid on it. I decided to finish the last gulp before I tossed it in the recycle.

Me: Oh, no! You didn’t drink that did you?! (Between tears and snorts)

Shawn: Yes! It was a delicious Mellow Yellow. But it wasn’t!!

Me: No! It was Heidi’s science experiment! (More tears, grabs a tissue to wipe eyes.)

Shawn: It was vinegar and baking soda! It was horrible! It tasted how it smells!

Me: *snort*

Heidi: Momma! Don’t laugh! It’s not funny!

Shawn: Yeah, actually it is…
