Carbon Dioxide Projects

A variety of sources

Kristen Byrnes, 8th Kingston Guides, Kingston ON:

Reaction of baking soda and vinegar to form carbon dioxide (CO2).... you need: 2 jars, one that is shorter and can fit inside the large one. In the large jar put in viniger. in the smaller jar put in the soda. carefully place the soda inside the large jar. The large jar also needs a lid with a straw in it. put the lid on the large jar with the straw and then tip the bottle over gently and CO2 will form. You could have them put out small fire like a candle or match as they have made a fire extinguisher (that's what they are really like!).

Susan Cokley, Leader Point Danger Guides, Gold Coast Region, Australia:

Another good idea for this experiment is to put several tablespoons of baking soda into a balloon and about a cup or so of vinegar into a small narrow necked bottle. Stretch the balloon over the neck of the bottle and allow the baking soda fall into the vinegar. What happens is that the mixture forms CO2 and blows up the balloon.
