Are you getting tired of blowing up balloons for these experiments? Here's a way to get chemistry to do the work for you!
What you'll need:
1 empty plastic bottle (about 20 ounces in volume)
Measuring spoon (1 tablespoon)
Funnel
Balloon
Vinegar
Baking soda
Pour about one inch of vinegar into the bottle. Using the funnel, put one tablespoon of baking soda into the balloon. Carefully stretch the balloon opening over the mouth of the bottle, letting the balloon hang down over the side, as shown in the photo above. When you're ready to go, lift the balloon up so that the baking soda falls down into the vinegar. You'll immediately see lots of bubbling, and will observe the balloon grow larger! What's going on?
Baking soda (chemical known as sodium hydrogen carbonate) reacts with vinegar (or acetic acid) to give off lots and lots of carbon dioxide gas, or CO2. The gas has nowhere to go but into the balloon! When the balloon is at its largest, remove it from the bottle and tie the end off to seal the CO2 in. Blow up another balloon of the same type using your breath to about the same size and tie it off. Can you tell the difference between the two balloons? Put them aside for a few hours, and we'll come back to them later.
hello im doing this experiment for my chemistry class and i need to write down info, who's the publisher?

Excuse me, that is not the correct way of talking. I am going to send you to the police.
