Volcano in a Bag

Anna and Addie love science. Recently they chose to attend a summer camp with this theme. Both girls are always game for an fun experiment. So I remembered reading that if you put vinegar, water, and baking soda in a bag, and shake it up, it will do fun things! We did this three different ways; it got a little better each time.

First we used a gallon-size Ziploc bag, 1/4 of a cup of water and  1/2 of vinegar and 1 tbps of baking soda. We put the baking soda in a paper towel and  folded it up like a burrito and taped the end shut with scotch tape. I held it at the top of the bag out of the vinegar while Anna zipped the bag shut, then I had her shake it up. 


It puffed up, but you could tell that it wasn't enough vinegar or baking soda.


So we increased the amounts to 1/2 cup of water, 1 cup of vinegar and 3 tablespoons of baking soda. We also decided to use a smaller bag. So we used a quart-sized bag. The results were much more pleasing. Anna laughed and laughed at how much the bag puffed up.


These bags were too thick to pop so we decided to use the same amounts as we did with the quart size bag, but we put it into a sandwich bad and it blew up and popped!


This was so fun. I highly recommend trying this out! We loved it so much we will do it again tomorrow with Addie (she was napping when we did this).
