We carry out many experiments and experiments in the kitchen, using what is found in the kitchen cabinets. Today I found vinegar. I present to your attention experiments with vinegar, which made us very happy.

Using vinegar:

• inflate a balloon;
• let's make a volcano;
• dissolve the shell;
• Let's make a rubber egg.

Volcano in a bottle

Using the reaction between soda and vinegar, we created a volcano in a bottle.

For the experiments we used:

Rubber egg

Using vinegar, a chicken egg, and If desired, quail can also be turned into “rubber”. Vinegar reacts not only with soda, but also with many other substances, one of them is calcium. The egg shell contains calcium.

To observe the interaction reaction, you need to place the egg in a glass with vinegar. We used 9% vinegar. After just 12 hours, the egg changed, it lost its hard shell. From the glass we took out a chicken egg that could bounce like a ball. But not overdo it! Our experimental egg jumped, jumped and burst right on the carpet in the room. Of course, the egg does not turn into rubber, the shell simply dissolves under the influence of acid, and the white and yolk remain “wrapped” in a thin film that existed before, but was not visible. An egg without a shell glows very beautifully if you shine a flashlight on it.

After experiments with eggs, we wondered what else could be dissolved in vinegar?

Dissolving the shell

Grandmother brought us beautiful shells from the sea. We decided to donate one of them to study its solubility. We believed that shells were made primarily of calcium carbonate and assumed that the calcium would react with the vinegar and cause our shell to dissolve. Tested empirically. We immersed the shell in vinegar, but no significant changes occurred within a day. Do you think we're disappointed? No! Once in vinegar does not dissolve, which means the acid concentration is too low. Soak the shell in 70% acetic acid. Over the course of 18 hours, the shell became significantly thinner, and after 48 hours it completely melted.

You need to be extremely careful with acetic acid!

Our solvent moods did not end there. A piece of chalk came into view. Here he is It must be great to dissolve! It turned out that we were mistaken. Having immersed a school chalk in a glass of vinegar, we observed a beautiful reaction of gas release, small bubbles enveloped the chalk. But the reaction quickly ended, leaving us disappointed. As we later found out, gypsum is added to school crayons, but it does not dissolve in vinegar.

Inflate a balloon using vinegar and soda

All baking lovers know that when baking soda and vinegar react, carbon dioxide is released. Using this knowledge you can inflate a balloon.

For this we need:

• plastic bottle,
• vinegar,
• soda,
• ball,
• funnel.

Pour about 100-150 ml of vinegar into the bottle. Pour 1 tablespoon of soda into the not yet inflated balloon. It is easier to do this by using a plastic funnel or making a funnel out of paper. Next, we put the ball on the neck of the bottle and straighten it. The soda begins to pour into the vinegar, a violent reaction between the two substances occurs, releasing carbon dioxide, which inflates the balloon. Joy on the child's face is guaranteed! Here is a video of our experiment.

We often use vinegar in our experiments. For example, in experiments with indicators under the influence of vinegar, liquids change color or we used it to clean coins.

Friends, which of today’s experiences did your child like best? The experiments are simple, but bring a lot of positive emotions to kids. I like to photograph children's smiles, their joy and delight. Send photos of your experiences and share your impressions in the comments.

Happy experimenting! Science is fun!

A children's party or corporate event will be brighter if there are balloons. A simple chemical experiment will allow you to inflate even a large number of them without much effort. Knowing how to inflate a balloon using baking soda and vinegar can save you a lot of time.

The method, which tells how to inflate balloons using simple and affordable products, is based on a chemical reaction that occurs in the process of combining substances such as soda and acid

This method is based on a chemical reaction. It occurs through the interaction of sodium bicarbonate and acid.

What's happening

Sodium bicarbonate is a basic powder substance. Vinegar is a solution of acetic acid in water. Acetic acid reacts with sodium bicarbonate, this process is called a neutralization reaction. During the reaction the following substances are formed:

1. Carbon dioxide.
2. Salt.
3. Water.

As the reaction proceeds, the volume of carbon dioxide increases inside the container. It fills the space completely. Not fitting into the given volume, it begins to exert pressure on the walls of the material. This helps the rubber stretch quickly. This is how vinegar and soda inflate the balloon.

Air is lighter than carbon dioxide. Therefore, an inflated decorative balloon does not take off.

As a result of combining sodium bicarbonate with an acetic solution, an instant reaction occurs, which gives a quick result.

A little chemistry

The formula and properties of acetic acid are known to us from chemistry lessons. It is a monobasic saturated carboxylic acid, which has an acid residue more powerful than that of sodium bicarbonate. As a result of the reaction of neutralization of soda powder and acetic acid, and the replacement of the acidic residue of sodium bicarbonate, sodium acetate is formed. The latter dissolves in water, so no solid sedimentation occurs during the experiment. As a food additive, sodium acetate is often used as a preservative.

The method of inflating a balloon using soda and vinegar without helium requires care and attention. Everything must be done quickly and in the right proportions

When an acid solution reacts with soda, the free space above the liquid is filled with carbon dioxide, which has a lower density than water. For this reason, the volume of gas can be several times greater than that of the original liquid. A good analogy is the steam from boiling water. At a temperature of 99 degrees, the density of the liquid is almost 2 thousand times higher than the density of water vapor.

The neutralization reaction effect is often used in cooking. The action of baking powder is based on this. Thanks to the molecules of carbon dioxide released during contact of water with a dry mixture of citric acid (or vinegar solution) and soda powder, the dough becomes “airy.”

What ingredients are needed

In order to inflate a rubber ball, you will need the following components:

• Plastic or glass container (1/2 l);
• Ocet (regular table vinegar);
• Soda.
• Dessert spoon.
• Decorative ball.
• Funnel.

The number of components depends on how many balloons need to be inflated.

How does this happen

Inflating a balloon using vinegar and soda is easy. In this case, you should be careful and careful. Everything needs to be done as quickly as possible, strictly observing proportions.

First, you need to pour 2-3 dessert spoons of soda into the ball. For convenience, you can use a special kitchen funnel.

The carbon dioxide released in this method helps the balloon inflate and take off.

Next, you need to pour 50 ml of vinegar solution into a glass bottle. After this, put a rubber ball on the neck of the bottle. This must be done so that sodium bicarbonate does not spill into the vessel. Then you should sharply straighten it so that the soda begins to crumble into the bottle with the acid solution. After this, a chemical reaction will occur with the release of a large volume of carbon dioxide, and the rubber walls will begin to swell.

The neck of the inflated decorative ball must be firmly secured with thread.

This manipulation can be carried out better and faster. To do this, the rubber ball needs to be inflated once with your mouth and then deflated. This way the material will stretch and be more manageable.

In order to inflate a larger number of decorative balloons, you need to pour a glass of table vinegar into the bottle and use at least 5-6 tablespoons of soda.

The main disadvantages of the method

This method, although interesting and does not require much time, has its drawbacks. It is not recommended to use it when organizing parties for very young children. If the balls start to burst, the consequences can be unpredictable. Harsh baking soda powder may get on your face or eyes.

Another disadvantage is the unaesthetic appearance of the material used. Traces of soda remain inside the balls. You can try to disguise this by choosing them from materials of colorful, rich shades.

You can also correct side effects using markers or paints. Anyone with imagination and talent can turn an ordinary ball into a wonderful interior element that can decorate even the most boring room.

Why doesn't he fly

Many people are interested not only in the answer to the question of how to inflate a balloon using ordinary table vinegar with sodium bicarbonate. People often ask what to do to make it fly.

The molecular weight of air is 29, carbon dioxide is 44.

If you want to please your children with beautiful flying balloons, it is recommended to fill them with methane, hydrogen or helium. You can also use acetylene, but in this case the flight will be short and not as exciting as you would like.

If the balls are needed only to decorate the room, then a combination of soda powder and vinegar is the best solution.

A simple chemical experiment will help you inflate balloons without any physical effort.

Doctors say that blowing up balloons is beneficial. It seems that this develops the lungs, eliminates all congestion in the bronchi, and therefore improves the well-being of those who smoke or are predisposed to respiratory diseases.

Inflating balloons is also useful for those who want to lose weight, because this simple procedure speeds up the metabolism. If you are stressed or depressed, breathe deeply and puff out your cheeks and balloons too!

However, everyone knows that if you blow for too long, your head starts to hurt. And you can’t help but think that it would be nice to have a helium tank, like in parks and other recreation areas where you can buy inflatable balloons.

There is a very simple way to inflate balloons without straining - for example, when a child asks “Mom, inflate the balloon!”, and dad will come to the rescue only in the evening.

Take vinegar and baking soda. First, pour about half of the vinegar solution into the bottle. Then pour baking soda into the ball with a narrow spatula. We put the ball on the neck of the bottle - again, the soda falls into the vinegar, and a violent chemical process begins, reminiscent of a volcanic eruption. This releases carbon dioxide. If you add baking powder to the dough in a similar way, quenching the soda with a drop of vinegar, that’s exactly what it is.

Gas is released and the balloon is inflated. One “but” - carbon dioxide is heavier than air, and your ball will not fly up, but will lie on the floor. It doesn’t matter, sometimes a lot of balls are needed just for a lying or hanging garland, and not for flying in the air.

Therefore, adopt a working idea!

Additional video instructions:

Multi-colored balloons always give a good mood. However, helium balloons are an expensive pleasure, so the question of how to make a helium balloon at home is often relevant.

Helium is a non-toxic monatomic gas, number two in the periodic table. It is a colorless and odorless gas, it is much lighter than oxygen and carbon dioxide. The molecular weight of helium is 4, while oxygen has 32 and carbon dioxide has 44. That's how light helium is! Therefore, balls filled with this monatomic gas can fly, while the mixture of oxygen and carbon dioxide weighs the ball down, causing it to fall. The lighter the contents of the ball, the more likely it is to fly.

Where can I get helium balloons?

Helium is produced by deep cooling of natural gases. Helium balloons are sold in circuses and specialty stores. To inflate such a balloon at home, purchase a special helium balloon. You can find out about the cost of the cylinder on the Internet. Unfortunately, it is impossible to produce helium experimentally chemically at home, so you will have to spend a significant amount. But you can conduct many other interesting experiments with balls, and at the same time gain new knowledge in chemistry.

Balloon inflated with soda and vinegar

A well-known chemical fact: the reaction of soda (NaHCO₃) and vinegar (CH₃COOH) is accompanied by abundant release of carbon dioxide. A ball with carbon dioxide, of course, will not fly due to its large atomic mass. But this experiment is very interesting, and the required solution can be prepared at home.

Balls filled with carbon dioxide

Show this trick to children to instill in them a love of chemistry: by inflating a balloon with a bottle, they will show interest in science, and perhaps little fidgets will make discoveries in the future.

What we need:

acetic acid, which is in everyone’s kitchen (there are different types of vinegar, but almost any will do);

baking soda;

empty bottle or flask with a volume of 1.5 liters;

gloves;

This kind of home trick is very easy to perform; even a child can do it. However, it is worth working with rubber gloves, since vinegar, especially strong vinegar, has an unpleasant effect on the skin: at best, a slight burn may occur. If this happens, you need to know that treating with soda or soap neutralizes acids. Therefore, it is better for children to carry out all experiments with dangerous chemicals by calling an adult for help.

So, we need to add soda to the ball (2 teaspoons per ball), and pour half a glass of acetic acid into the bottle. Don't rush to add too much baking soda. We put the ball on the bottle: the soda from the ball will pour into it, and a violent reaction will begin with the intense release of CO₂. Therefore, the balloon will inflate. If the reaction is weak and the balloon does not inflate, add more vinegar and soda, but do not shake the solution. This method is convenient for those who find it difficult to inflate balloons.

What experiment will make a balloon take off without helium?

This method will tell you how to make the ball fly. The experiment works, but keep in mind that this simple experiment is a fire hazard, so do it outside. You will also need safety glasses, a gown and gloves.

For the experience you will need:

aluminium foil;

water at room temperature;

• pure sodium hydroxide;

  glass flask.

You may also need the help of a partner. Pure sodium hydroxide can be found on hardware store shelves. For example, the Mister Muscle drain cleaner contains the substance needed for the experiment in its pure form. Try using other products with similar composition.

To begin, take the foil and roll ten small balls out of it that will fit into the hole of the flask. Pour the pipe cleaner into a flask and fill the substance with water. One sachet will require half a liter of water. Next, add all the balls that you managed to make into a container with water and cleaning solution. Do not shake the resulting solution, because a strong reaction will begin. The balloon, of course, will inflate, but condensation from the evaporation of gas will remain in it, which will make it heavier. Therefore the ball will not take off.

If the solution is not shaken, the reaction will proceed calmly. You can also do this: wait additional time so that the condensate inside the ball flows back into the flask. Therefore, for the experiment to work, you need attentiveness and patience. The result will not be long in coming: your balloon will fly no worse than a helium balloon!

Ball filled with hydrogen

This way we will get the desired effect. The substance released from the resulting solution contains explosive hydrogen. Therefore, you not only need to do the experiment on the street, but it is also dangerous to keep the balloons at home: if there is a spark nearby, the hydrogen will explode. You can find out what experiments with hydrogen can be done at home. During the experiment, you also need to be careful: if you add a lot of foil and product or start shaking the contents, you can get burned by the flask. Do not inhale the escaping gas.

A party is always great. Decorate your holiday with bright balloons that will fly. Don't worry if you don't have the money or time for helium. At home, you can easily inflate balloons with soda and vinegar.

This will be a visual aid for children simple chemical experiment. And it won’t take much physical effort.

By the way, scientists say that inflating air products is good for the lungs and heart; it burns calories, which means it also helps you lose weight.

But if we are talking not about one specimen, but about ten, twenty or more balls, you must agree that pleasant entertainment will become torment...

Soda and vinegar for the ball

It's simple. At the heart of the “magic” - an ordinary chemical reaction when combining acid and sodium bicarbonate. This releases carbon dioxide, which instead of helium helps the ball fly. Everything happens instantly, the result will please you within a few seconds.

Conducting an experiment

We will need:

• vinegar
• balloon
• funnel
• plastic bottle (0.5)

It is important to maintain the correct proportions - the final result depends on this.

Wear gloves! Do not allow small children to prepare the mixture themselves - only under adult supervision!

1. Pour 100 ml of vinegar into a plastic bottle. We insert the funnel into the neck, pour 1 tablespoon of soda into it.
2. The reaction has just begun. At this time, we put a rubber product on the neck of the bottle. Under the influence of carbon dioxide and heat, our balloon begins to inflate.
3. Don't miss the moment when to remove it from the bottle and tie it with thread. Try to launch it upward - it can fly under the ceiling!

Here's how to inflate a balloon using slaked soda. The method is inexpensive, fun and simple. These are the advantages.

However, particles of bite and soda may remain inside the product (so choose a darker color or color it with felt-tip pens). Well, you should only work with vinegar under adult supervision.

These are, to list, the disadvantages.
