QUIZ TIME: Lets take a quiz to test your understanding.👇 👇

Blowing up balloons without actually blowing them👇 👇

STEP1: Take out Baking soda, vinegar, a bottle, a funnel, and a balloon.

STEP2: Stretch the opening of the balloon over the end of the funnel. Pour about 1/3 cup of baking soda into the funnel and shake it around a bit until it all falls through the funnel and into the balloon. Just make sure you hang onto the balloon opening so it doesn’t fall off the funnel.

STEP3: Rinse all the baking soda off the funnel (or you’ll get fizzing), and then use the funnel to pour the vinegar into a soda or water bottle. Fill the bottle to about 1/3 of the soda bottle full, or if you are using a smaller water bottle, fill it up halfway.

STEP4: Gently stretch the opening of the balloon over the opening of the bottle. Make sure the balloon is draping down at the side to keep the baking soda from falling in.

STEP5: Lift the balloon so that it is completely upright allowing all of the baking soda to fall into the vinegar.

STEP6: The balloon seemed to be on the bottle pretty snugly, but I’d still recommend pinching it onto the bottle opening the whole time.

STEP7: As soon as the chemical reaction began, the balloon started to inflate! The more vinegar and baking soda you use, the bigger your balloon will get!

Notice how the balloon inflates, also observe that this balloon moves faster than a normal air filled balloon. If you are unable to follow, click LEARN MORE to go to the video and follow the procedure there.

REASON:

When baking soda and vinegar are mixed, a reaction takes place which releases a gas and that gas(carbon dioxide) has filled the balloon. The reason for the balloon moving faster than a normal air filled balloon is because carbon dioxide is heavier than air.
