Learn how to inflate a balloon in this fun science experiment using these common kitchen ingredients! Balloons inflated this manner are filled with carbon dioxide produced past the 2 ingredients reacting. They practise not incorporate helium, so they will not float.

1
Pour a little vinegar into a plastic bottle. Cull a plastic water bottle, or another bottle with a narrow neck. Cascade ane–2 inches (ii.5–5 cm) of vinegar into the bottle, using a funnel if you accept one. Apply white vinegar, besides chosen distilled vinegar, for the best result.
- You lot tin try this with whatever kind of vinegar, just the aggrandizement might take longer or require more vinegar to work. Other types of vinegar tend to be more than expensive also.
- Vinegar can damage metal containers, potentially calculation an unpleasant taste to nutrient and drink stored in that container. If you take no plastic bottles, use a high-quality stainless steel bottle to minimize the chance of this happening. Weakening the vinegar with an equal amount of water might also help, and won't forbid the airship from inflating.^[1]
ii
Apply a funnel or harbinger to put a little baking soda into a limp airship. Y'all can use any shape and color of airship. Hold it loosely by the cervix, with the open side of the balloon facing towards you lot. Fit a funnel into the neck if you have one, and so pour about ii tablespoons (30 mL) baking soda into the balloon, or just fill up the balloon well-nigh halfway total.^[two]
- If yous don't take a funnel, yous can place a plastic straw into a pile of baking soda, put your finger over the meridian pigsty of the harbinger, then poke the harbinger into the balloon and lift your finger. Tap the straw to get the baking soda to fall out, and repeat until the balloon is at least 1/3 of the manner full.^[iii]

Stretch the neck of the balloon over the top of the canteen. Be careful not to spill the baking soda while you do this. Hold the airship'south neck with both hands and stretch it over the height of the plastic bottle containing vinegar. Have a friend keep the bottle steady if the table or bottle is wobbly.^[four]
4
Lift the balloon up over the bottle and sentinel the reaction. The blistering soda should fall out of the balloon, through the neck of the bottle, and into the vinegar at the lesser. Hither, the two chemicals will fizz and react, turning into other chemicals. One of these is carbon dioxide, a gas, which will rise upward and inflate the airship.
- Milkshake the bottle gently to mix the two ingredients if in that location's not much fizzing.
5
Try again with more vinegar or blistering soda, if it doesn't work the first time. If the fizzing has stopped and the balloon all the same hasn't inflated after you count to 100, empty out the bottle and try again with more vinegar and baking soda. The stuff left in the bottle has turned into other chemicals, more often than not water, and so it tin can't be used again.
- Don't go overboard. The bottle should never be more than virtually 1/iii full of vinegar.

Larn about chemical reactions. Only about everything around yous is made upward of molecules, or unlike types of substances. Frequently, two kinds of molecules react with each other, breaking up and forming different molecules out of the pieces.
2
Learn about baking soda and vinegar. The reactants, or substances that reacted with each other in the fizzy reaction you saw, are baking soda and vinegar. Unlike many ingredients in your kitchen, both of these are simple chemicals, not complicated mixtures of many chemicals:^[5]
- Blistering soda is another word for the molecule sodium bicarbonate.
- White vinegar is a mixture of acetic acrid and water. Only the acerb acid reacts with the baking soda.
three
Read about the reaction. Baking soda is a type of substance called a base. Vinegar, or acetic acid, is a type of substance chosen an acid. Bases and acids react with each other, partially breaking autonomously and forming different substances. This is described as "neutralization" because the end result is neither a base nor an acid. In this example, the new substances are water, a kind of table salt, and carbon dioxide.^[6] Carbon dioxide, a gas, leaves the liquid mixture and expands throughout the canteen and the balloon, inflating it.
- Although the definition of acid and base tin can get complicated, you lot can compare the differences betwixt the original substances and the "neutralized" outcome to meet at that place are obvious changes. For instance, vinegar has a strong smell and can be used to dissolve grime and dirt. After existence mixed with baking soda, information technology smells much less strongly and is no more effective at cleaning than water is.
4
Study the chemical formula. If you're familiar with some chemistry, or curious about how scientists describe reactions, the formula beneath describes the reaction between sodium bicarbonate NaHCO_iii and acetic acrid HC_twoH₃O₂(aq). Tin can you figure out how each molecule splits apart and reforms?
- NaHCO₃ + HC₂H₃O_two(aq) → NaC₂H₃O₂(aq) + H₂O(l) + CO₂(g)
- The letters in parentheses show the state the chemicals are in during and later on the reaction: (chiliad)as, (50)iquid, or (aq)ueous. "Aqueous" means the chemical is dissolved in water.

Add New Question

Question

What happens if I change the bottle size?

If y'all reduce the bottle size (volume) without changing the amount of soda and vinegar, so the balloon will blow faster and bigger.
Question

Does it affair how much baking soda I put in the canteen?

Aye, because if you put too much it will pop and if you put likewise picayune, it will not inflate.
Question

If the balloon is thick and hard to blow up, will this still work?

Yes, it should all the same piece of work correctly.
Question

Why did the balloon terminate blowing upwardly?

The forrad reaction between the two reactants stops, and the reaction reaches equilibrium. Thus, no more CO2, or H2O is produced to inflate the balloon more.
Question

Does the size of the bottle touch on the balloon aggrandizement?

No, it will not touch the balloon inflation.
Question

How can I do it in a school project?

Merely get the baking soda and white vinegar. It is a very simple experiment. Record the balloon when the mixture of blistering soda and vinegar inflates.
Question

Why should I not do it with glitter or food coloring?

Because it is a science experiment and not an art project.
Question

What is the purpose of inflating a balloon using blistering soda and vinegar?

The purpose is to see what happens when carbon dioxide is produced. It's a basic science experiment.
Question

Does information technology still change your vocalisation?

No, as baking soda and vinegar create carbon dioxide, a greenhouse gas. Helium and sodium hexafluoride alter your voice.
Question

Does the balloon bladder later I exercise the experiment?

No.

This method can also be used in homemade cardboard or plastic rockets and yous tin make them become a long manner if ingredients are out right. The reason it blows up is because the reaction creates gas, and the pressure builds upwardly.
You lot can use lime juice instead of vinegar.

Thanks for submitting a tip for review!

Advert

If the balloon is fully inflated and the liquid is still fizzing, the airship might be well-nigh to explode. Decide whether you have fourth dimension to pull off the airship, or whether yous should just encompass your face before it gets spattered!

Article Summary X

To blow upward a balloon with baking soda and vinegar, pour i–2 inches of white vinegar into a plastic bottle. Next, concord a balloon loosely by the cervix, fit a funnel or plastic harbinger into information technology, and cascade 2 tablespoons of blistering soda through it into the balloon. So, stretch the neck of the balloon over the top of the bottle earlier lifting the balloon upward over the bottle. The baking soda volition fall out of the airship, through the cervix of the canteen, and into the vinegar. The 2 ingredients will buzz and react to create carbon dioxide, which will and then inflate your balloon! If you want to larn more virtually the chemical reaction that occurs, continue reading!
