👍💧💨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.

💚💞my sculpture

                                              This sculpture was inspired by Aunty Jo's picture

which is hanging in my room. The picture has a big waterfall and a small waterfall and a river, lots of trees, a tree stump and mossy rocks,  some ferns, and moss, some sky and some of her writing (signature). I was trying to create this picture in a jar. I found a fern and lots of moss and rocks. I tried to put water in there, but it didn't stay there. I was going to put moss on the lemon, but I forgot about that. That was trying to make the stump. I tried to make the stick look tree-like but I didn't have scissors then so I couldn't cut it far enough back, so it looked just like a big leaf. I put the tree of life
on it because of the writing on the back of the picture (it says provision of life). The ferns also represented the All Blacks logo. I enjoyed finding the fern. I enjoyed taking the photos. I hope you like it. I tried my hardest. Do try this at home. It is safe!
