Carbon Dioxide Balloons

Last night, when I was playing Frisbee with my son, I noticed a red balloon on the ground under one of the bushes.  I figured my kids had something to do with it being there.

"Dude," I said.  "Why is there a balloon under the bush?"

"We did an experiment, Mama."

"An experiment?"  I couldn't wait to hear about this one.

"Yeah.  We made carbon dioxide balloons and released them into the wild."

I raised my eyebrows.  "Is that so?"

He nodded. "Do you want to see how?"

"Sure," I said.  We went inside. He took a pop bottle, filled it with water, then added baking soda and vinegar.  He quickly attached the balloon to the bottle.  What happened next, was that the balloon expanded.  He took it off the bottle, keeping the neck of the balloon closed so the air wouldn't escape.  Then he marched outside and released it.  The balloon zoomed through the air and landed under another bush.

"Very nice," I said.  "Now you can march around the house and clean up all the balloons you have released into the wild!"

(If you'd like to do the experiment, you can find the instructions here.)



One more thing before I go:
