The mixture of vinegar and baking soda can produce a memorable science experiment. The substances can be arranged to "magically" blow up a balloon through the generation of carbon dioxide. Allow children to do some of the steps on their own. Consider doing this experiment outside since it can create a mess.

Step 1

Pour 2 tbsp. of vinegar and 2 tbsp. of water into the bottle.

Step 2

Put 2 tbsp. of baking soda into the balloon using the funnel.

Step 3

Stretch and secure the opening of the balloon over the neck of the bottle while being very careful not to dump the baking soda into the bottle just yet.

Step 4

Straighten the balloon to an upright position, allowing the baking soda to fall into the vinegar in the bottle. The chemical reaction should blow the balloon up.
