Today we had to do a balloon experiment. We had to make the balloon blow up with just a bottle, vinegar and baking soda. We have taken a video and if you want to watch it you can go to the bottom of my blog post and watch it I hope you like the experiment. We have had so much fun doing the experiment it blow up the balloon about halfway and then we taped the bottom of the bottle and then nothing happens. And then I had to stop the video beacuse if I had left it on you will just be looking at the bottle beacuse it was just not doing anything.
When you mix baking soda and vinegar together something new is foamed.
The baking soda is having a reaction to the vinegar and it is creating gas.
We noticed as the soda hit the vinegar it started to bubble.
Puting the ballon over the top of the bottle so it did not break.
Next time I will try to use more vinegar and baking soda as the more gas you create the bigger the balloon hopefully.
The gas it has created is call Carbon Dioxide.
Hola Cameron,
ReplyDeleteWell done for making this science experiment work. Why does carbon dioxide blow up the balloon?
Maybe you could alter the experiment and answer these questions?
Does water temperature affect how fast the balloon fills up.
Does the size of the bottle affect how much the balloon fills?
Can the amount the balloon fills-up be controlled by the amount of vinegar or baking soda?

ReplyDeleteGreat experiment. I'm really impressed with your blogging, TS really neat that you have added a video to your blog of this experiment. Do you think uh our ballin would have got much bigger if you used a smaller bottle? I'm looking forward to visiting your blog again tomorrow Cameron. Ka pai to mahi i tenei rā.

kia ora cameron i like how you explained how the balloon blew up from all the carbon dioxide keep up the good work

Hi Cameron,
ReplyDeleteThanks for sharing your experiment and for explaining the science behind it. You could try your experiment again and change one of the variables to see if the results vary - e.g. lemon juice instead of vinegar for the acid.
God bless & have fun as you explore the scientific world through kitchen chemistry.
