Cold Air Balloon Observation Part 1 and 2

 During science, we we're learning about what an endothermic reaction, we made one by filling up a balloon with baking soda, vinegar, a measuring cup and a bottle. When we added the baking soda and the vinegar it caused a chemical reaction, causing the balloon to inflate.

What happened? When vinegar and baking soda mix, an endothermic reaction occurs. This produces carbon dioxide which inflates the balloon. The endothermic chemical reaction will also lower the temperature in the area surrounding the vinegar and baking soda so significantly that you will be able to easily notice the change in temperature.

I observed/predicted that when the baking soda and the vinegar mix, the balloon will blow up so much that it'll pop, luckily it didn't happen because if it did, most of our chromebooks would be affected by the mix.

We tested it and it didn't go as good as I expected it to be, when Mrs Bava attached the balloon to the milk bottle, it had a slight rip in it, that's what caused it to splat everywhere. 

Here is a video to learn about it:
