Magic Balloons

We have been experimenting with chemical reactions again. We put vinegar and baking soda together and watched as it inflated the balloon over the container. When the vinegar and baking soda mixed they created a gas-CO2, which is carbon dioxide. The gas couldn't escape so that's what filled the balloon, just as if we were blowing it up.

It's a gas exploding !!!!

On Thursday the 30th of June we did a science experiment.It was about chemical reaction.
First we put baking soda in a sandwich bag.Then we put vinegar in a plastic cup.We had to place the cup in the bag with the baking soda in.Next we tipped the vinegar into the baking soda .Then we watched it explode.The vinegar dissappeared and it fizzed and foamed up.
