Here is another balloon based science experiment that you can perform. We use the by product of a simple chemical reaction to inflate a balloon. Here’s what all you will need to conduct this experiment.

A half liter water bottle, a balloon, a cup of white vinegar, couple of spoons of baking soda and a funnel. In case you don’t have a funnel handy you can make one out of plain paper by making a cone and taping it to hold it in position.

Stretch the balloon out a bit by pulling it along to loosen the rubber in it. That way it will be easier  Now use the funnel or paper cone to fill the baking soda into the balloon and keep it aside. Pour the cup of vinegar into the empty water bottle.Very carefully without letting any of the baking soda fall into the bottle attach the mouth of the balloon onto the open mouth of the water bottle that contains the vinegar.

Make sure that its a good fit and no air can escape out of the sides. Now hold up the balloon straight so that the baking soda inside can fall into the bottle. As the baking soda reacts with the vinegar the reaction will cause the release of a large amount of carbon dioxide which will shoot up into the balloon and inflate it. A simple science experiment that you can amaze your friends with.
