Blowing Up a Balloon

Room 22 learned about states of matter and how matter changes.  One of the activities we did was blowing up a balloon without using our mouth!  Anna M. blew up a balloon by combining a solid (baking soda) and a liquid (vinegar) in a clear, empty bottle.  We learned that by combining these two types of matter, we can create the third type of matter called gas.  In this activity we created a gas called carbon dioxide.
