#Blow-Up a Balloon Using Science!
Using items easily found at home, you can blow up a balloon without using your mouth or your own breath. In this demonstration, Akshara & Anagha will perform a reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) in order to inflate a balloon and to introduce the concept of a basic chemical reaction to all here.
The reaction of sodium bicarbonate (baking soda) and acetic acid (vinegar) produces carbon dioxide gas (CO2), water, and sodium acetate. The carbon dioxide gas can originally be seen as bubbles in the solution, but will quickly be released from the solution. The amount of carbon dioxide gas will exceed the space in the bottle, and will move into the deflated balloon, and will inflate it. A clear solution will be left in the bottle upon completion of the reaction, it is a solution of water and sodium acetate.
Every chemical reaction is accompanied by a change in temperature. Sometimes the change is barely noticeable, but sometimes it is extreme. Sometimes the temperature goes up, but sometimes it goes down. Here in this activity, it took energy to break the baking soda and vinegar apart and energy was released when the carbon dioxide, sodium acetate, and water were formed. Since more energy was needed to break the baking soda and vinegar apart, it takes heat from its surroundings leaving the bottle feeling cold. This reaction is called an endothermic reaction.
▶ Supplies Needed:
Baking Soda
Vinegar
Empty Bottles
Balloons
Spoon
Measuring Jar
Funnel (optional, but helpful)
▶ Directions:
1. Measure 1/2 cup, approximately 125ml of vinegar, and pour it into the empty bottle.
2. Stretch the opening of the balloon over the end of the funnel and add about 2 teaspoons of baking soda into the funnel and tap it around a bit until it all falls into the balloon.
3. Secure the balloon around the opening of the bottle, but make sure the balloon is draping down at the side to keep the baking soda from falling in.
4. Lift the balloon, straightening it out over the opening of the bottle so that it is completely upright allowing all of the baking soda to fall into the vinegar.
5. Watch the magic as your balloon begins to inflate! The baking soda will quickly react with the vinegar in the bottle, creating carbon dioxide gas as one of its products, causing the balloon to quickly inflate.
This was such a FUN science experiment!
