in science today we were learning about cold air balloons were we put baking soda into a balloon and vinegar in a bottle so then there was a chemical reaction
I observed the experiment we watched showing us how to do the experiment.
I found it hard to think of what chemical reacts that way to baking soda.
I found it easy to insert the video into my blog to show other people how to do what we did
next time I will work harder and avoid the distractions around me.
