👍💧💨Poof! # A Big Mess

I put some vinegar in a bottle and a zip lock bag filled with baking soda over the top of it using a hair tie and tipped the baking soda into the vinegar and waited until the zip lock bag blew up.

Questions:

1. Does the temperature change how much the balloon fills up? Maybe.

2. Does the size of the bottle affect it? Yes. Cos if the bottle is small less of the air can stay in the bottle and it gets pushed up into the balloon.

3. Does the amount of vinegar and baking soda affect how much the balloon fills up? No

How it works.

The bag blew up because of the chemical reaction which is called an acid/base reaction, which pushes the air into the balloon/zip lock bag.

What I Noticed

I noticed that some of the baking soda came out of the zip lock bag onto the table because I didn't tie the zip lock bag on fast enough. And then I quickly looped the hair tie around the neck of the bottle and it stayed tight. And then I tipped the rest of the baking soda into the bottle. And then the bag blew up/inflated. Then the bag felt tight and hard to squish.

What Was Challenging

Finding the zip lock bag, because we didn't have a balloon. Getting the baking soda out of the bag and into the bottle.

What Would I Do Differently

Use a balloon.
