I wanted to see what would happen if I put baking soda and vinegar into a bag because I have heard what happened.
Materials:
•Baking soda
•Vinegar
•a bag
•flask
•spoon
What we did was put baking soda into the bag, twist it than we poored the vinegar into the bag closed it tightly and we untwisted the baking soda and the bag started to exspand and got cooled. After that we tryed a glove to see if it would expand but it had failed we believed it didnt work because we didnt add enough vinegar so we added more and than it started to exspand but it didnt get cold.
