Soap bubbles attract everyone with their beauty, iridescent tints, amazing fragility and lightness. Children and adults enjoy watching this amazing creation of man. Their intricate flight paths make soap bubbles a fun toy for kids of all ages. How to get large, multi-colored soapdo-it-yourself bubbles
Rationale.
Soap bubbles from time immemorial have always pleased the eye. They are interesting to watch. Their color is mesmerizing. How great it is to watch beautiful and iridescent soap bubbles that rise up, sparkling with all the colors of the rainbow! The slightest gust of wind - and the bubbles scatter in all directions. And it's always a shame when they burst. In the course of our research, we decided to learn how to make a solution for soap bubbles and get different shapes, so that we can use them ourselves at home and on holidays, as they create an atmosphere of joy and endless happiness. The project allows answering the question: what solution is needed to inflate large and strong soap bubbles? In the practical part of the project, experiments were carried out on the manufacture of various solutions of soap bubbles with different soap-containing liquids. During the experiment, it was found that it is impossible to inflate a bubble from water, soap-containing liquids with the addition of glycerin are needed.

What is a "soap bubble"?
They say that a person does not get tired of looking at three things: fire, water and the starry sky. It is necessary to add soap bubbles as the fourth point. Let's analyze this fact from the point of view of a simple layman. Looking at floating soap bubbles, both children and adults are breathtaking. How much pleasure we get by inflating and watching the play of all the colors of the rainbow on their surface. Soap bubbles are popular all over the world.
What is this rainbow miracle - a soap bubble?
In the "Explanatory Dictionary of the Russian Language" Ozhegov Sergey Ivanovich there is such a definition: A transparent ball filled with air in a liquid, liquid mass. Soap item (blown out of soap suds; also translated: about something bright, but fragile, about an inflated size; disapproved).
Origin of the soap bubble.
On the Internet, we learned the history of the appearance of soap bubbles. She is associated with a man named Pampatus, who, due to his fear, unknowingly invented a way to blow soap bubbles.
One fine day, when soap was finally created, the king, not joking at all, ordered everyone to wash themselves with soap under pain of death. Only one old shoemaker named Pumpatus sat hidden in his booth. More than anything, Pumpatus disliked washing his neck. Footsteps were heard outside the window. Two huge guards took Pumpatus under the armpits and five minutes later they brought him to the city prison. The room where Pumpatus was locked up had a bubble bath and lots of towels. "I agree?" asked the two huge guards. "Never!" Pumpatus answered. And they left him to smoke his pipe for the last time. Pumpatus inhaled and suddenly saw that a beautiful transparent ball flew out of the pipe. The ball flew out the window and shone in the sun: small rainbows jumped in it. After the first ball flew the second. Pumpatus watched the miracle happening with all his eyes. Passers-by below also lifted their heads to look at it. Soon a crowd gathered and there was a commotion. Everyone, of course, forgot that Pumpatus was to be executed. The professor, who had been invited to sort things out, examined the Pumpatus pipe. “Soap foam got into the tube. Here's the thing," the professor announced to the crowd outside the window. Nobody smoked pipes that day. Everyone filled the tubes with soapy foam and blew bubbles. The whole sky was multicolored from soap bubbles. Ladies began to give bouquets of soap bubbles. True, such bouquets burst, but instead of them they had to give new ones right away. And the ladies were happy. Pumpatus, of course, was not executed, and after that soap bubbles became popular not only in one small kingdom, but in the whole world!
Why is a soap bubble round?
We all admire bubbles, especially soap bubbles - their perfectly round shape and iridescent surface with different colors. CharlesBoys called soap bubbles an excellent experimental object and pointed out that the forces that give shape to a bubble are present in all liquids. These forces are omnipresent. Tea brewing is indispensable without them, without them it is impossible to close the current tap in the kitchen, they are remembered when diving into the water. In general, any liquid has this power. Imagine that we are filling a balloon with water. The more water we pour into it, the more the rubber shell of the ball stretches. Eventually, it will stop stretching and burst. Now imagine a drop of water. Water collects at the tip of the pipette in the form of a growing drop. The drop gets bigger and bigger. Finally, it reaches a certain critical size and breaks away from the pipette tip.
Charles Boys was so intrigued by soap bubbles that he wrote a 200 page book, Bubbles. Their color and the powers that give them shape."
So why is a soap bubble round?The reason for this is the surface tension forces of the liquid.The forces of surface tension tend to make the soap bubble as compact as possible. The most compact shape in nature is a sphere (not a cube, for example). With a spherical shape, the air inside the bubble evenly presses on all parts of its inner wall (at least until the bubble bursts).
Writers and poets about soap bubbles
Soap bubbles cannot leave anyone indifferent: neither a clown, nor a scientist, nor adults, nor children, nor an artist, nor a writer, nor a poet. For example, the famous American writer Mark Twain said: “A soap bubble is the most beautiful and most perfect thing that exists in nature.».
And Russian children's poets wrote poems about this phenomenon.
1. E. Blaginina "Soap Bubbles".
2. S. Marshak "Soap Bubbles"
3. R. Sef "Soap Bubble".( Appendix No. 1)
Soap bubbles and artists
The topic of soap bubbles was not bypassed by artists either. Appendix 2
Looking at the painting "Bubbles" (1733-35) by the famous French artist Jean Baptiste Simeon Chardin, we see children blowing soap bubbles on a beautiful sunny day. As you know, the great Rembrandt did not bypass this topic. He painted the painting "Cupid with a Soap Bubble". Also no less famous oil painting by John Everett Millet "Soap Bubbles" (1885-1886). ( Appendix 2)
Practical stage
At the beginning of my research, I conducted a survey among elementary school students, in which 33 people took part. The students were asked the following questions:
Do you like blowing soap bubbles?
Not really
Not really
Yes No I don't know Making your own bubbles
What do you most often use to make soap bubbles?
shampoo detergent soap powder other
round square oval cylindrical others. The results of the survey (Appendix No. 3).
As can be seen from the results of the survey, soap bubbles are a favorite pastime for elementary school students, which cheers them up. Bubbles soar in the air, brimming with all rainbow colors and always bring a smile. You can always buy a small jar of soap solution in the store, which some children (10 people) do. However, it ends quickly. Most of the guys (22 people) independently dilute the composition for soap bubbles. They listed the following as ingredients for the solution:
Shampoo (12 hours), detergent (10 hours), soap (11 hours). When blowing soap bubbles, the guys got round bubbles (27h), square (0h), oval 6h).
I myself have diluted solutions for soap bubbles at home more than once, and recently I began to think about whether there are such solutions from which soap bubbles of large sizes are obtained and which do not burst for a long time.
So I decided to do a few experiments and find out what soap bubbles are best made from, and what solutions give the soap bubble a long life.
.
You can find many recipes for soap bubbles on the Internet, but it’s hard to understand which one is better, I’ll try to independently explore 4 compositions for soap bubbles. (Appendix No. 4)
So, how to make soap bubbles?
First way:
For 200 ml of liquid dishwashing detergent, you need to take 600 ml of water and 100 ml of glycerin (available at any pharmacy). Mix everything well and your solution is ready.Glycerin is exactly the remedy that makes the walls of the soap bubble stronger, and the bubble itself, respectively, longer-lived!
Second way:
This soap bubble recipe is more complicated and the preparation of the solution will take more time. For 600 ml of hot water, you need to take 300 ml of glycerin, 20 drops of ammonia and 50g of any powdered detergent. We mix all the ingredients and leave to brew for two to three days. After that, the solution is carefully filtered and put in the refrigerator for 12 hours. And finally, you can start blowingrainbow beauties . From such a mixture, very large and all sorts of curly bubbles can be blown,because glycerin makes them stronger.
Third way:
Rub a piece of laundry soap on a coarse grater. Dissolve the resulting soap shavings (4 tablespoons) over low heat in 400 ml. hot water. Just be careful, a thick hot soapy solution - the same as hot jelly - can be badly burned. Leave the solution for a week, after which add 2 teaspoons of sugar to it. Leave until sugar dissolves, mix - ready.
Fourth way:
From my personal experience, the following recipe for soap bubbles turned out to be the simplest and most effective: 0.5 cups of baby shampoo; 1.5 cups of water; 2h. spoons of sugar.
In my experiment, the solutions of dish detergent and shampoo turned out to be the best, and the best fixture for blowing - a tube from a toy "soap bubbles".(Appendix No. 5)
Soap bubbles in the cold or in the freezer.
A small note about the behavior of soap bubbles in the cold seemed very interesting to me, and I decided a try. In the first way, I became a on the street, blow soap bubbles through a plastic tube from a ballpoint pen.
The effect of blowing soap bubbles in the coldexceeded all my expectations - it was an amazing sight! It seems that the bubble is covered with a thin crust of ice - it crystallizes.
I also tried putting soap bubbles in the freezer. I tried to freeze! blew a ball and put a it on the flannel surface. Kept in the freezer a very little. What did I see a ? A thin crust formed on the bubble. He was cold and looked like a Christmas toy!
My records with soap bubbles.
I blew the largest soap bubble with a diameter of 35cm.We played tennis with soap bubbles with our classmates. Tossed with smooth movements, and they bounced (Wrap rackets with a woolen scarf!)
We were blowing bubbles within bubbles. (Moisten the surface with a solution, then use a straw to blow out a large bubble. Carefully pierce our dome with a straw and blow another bubble inside it. And one more.
How can you diversify the process of inflating soap bubbles?
Make crafts!
Blow bubbles inside bubbles!
Play tennis with classmates.

Conclusion
In the course of my work, I answered the question that soap bubbles are a thin film of soapy water. Cooked a four recipes for soap bubbles at home and determined the easiest and most effective recipe. Soap bubbles in the cold freeze, covered with a crust. To do this, she conducted experiments and studies, observations, used literature sources and the Internet, set and your records.
Dear friends, blow a soap bubble and look at him: maybe you will find something interesting in his life!

Quietly whispering with willow
Old birch.
Walks around the yard with a broom
Grandpa Seryozha.
- Grandfather Seryozha, look,
We're blowing bubbles!
You see, in every bubble -
By crimson dawn
Along the birch, along the willow,
According to Seryozha, according to the broom.
You look, look, look:
Bubbles flew -
Red, yellow, blue, -
Choose any one!

Broke off the tube
Here he swam
Like a boat
Left, left, left ... then
Through the balcony
And disappeared around the corner.
I ran
This ball is not without reason -
He will grow
Becomes a rainbow ball.
I will attach to it
From the bottom of the gondola
And I'll fly
Slowly back to school.

Take in a glass
Let out of soap suds
We will bubble.
Straw simple
Now I'll take it in my mouth
I will draw water into it,
Then I puff a little
Into a straw - and behold,
Shining with a smooth film,
Stretching out,
Comes out tender, thin,
Colored bubble.
It burns like a peacock's tail.
What flowers are not in it!
Purple, red, blue,
Green, yellow color.
An inflated balloon takes off,
More transparent than glass.
Inside it is like
Mirrors sparkle.
Lights in space
Plays a light ball.
Then the sea turns blue in it,
It's on fire in it.
He is puffed up with air
Floats through the air
But even one minute
Does not live in the world.
elegant, colorful,
He broke forever
Spread out unnoticed
Disappeared without a trace.
And he was so haughty
Such an arrogant one!
Boasted that from the foam
He was born marine.
It had so many colors
There was such arrogance
And he - water and soap
Bloated mixture.
I don't feel sorry for him...
In truth,
Poems about him are longer
All the life of the bubble!

Introduction
Soap bubbles are a favorite pastime for children and even adults. They soar in the air, shimmering with all rainbow colors, and always cause a smile.
A small jar of soap bubbles, now you can easily buy in the store. However, it ends quickly, and they also do not have a very good composition, and the expected fireworks of soap bubbles are limited to only a dozen small bubbles.
So we thought about how to make a solution for soap bubbles on our own. And even better, soap bubbles of large sizes are obtained from such a solution.
Many of us try to blow big soap bubbles by experimenting endlessly with shampoos, powders and soaps. However, in such a seemingly simple, soapy business, we found a lot of tricks. Of course, it all depends on the composition of the soap bubbles. We found ten recipes for soap bubbles, but it’s very difficult to understand which one is better, so we decided to try them all.
The purpose of our study:preparation and testing of soap bubble solution at home.
Tasks:
Learn what bubbles are
Find various recipes for making soap bubbles in the literature,
Conduct experiments to determine the quality of the prepared solution for inflating soap bubbles.
We put forward the following hypothesis: soap bubbles of large sizes are obtained only from the factory solution.
An object research: soap bubbles.
Subject research: the composition of soap bubbles.
Soap bubble, perhaps
most amazing and most
Exquisite natural phenomenon.
Mark Twain.
"Blow a bubble
and look at it:
you can practice
lifelong study of it,
Never stop extracting
Lessons from it…”.

Mystery 1: The origin of the soap bubble.
Bubbles as a phenomenon of nature have always existed, but they could not have arisen before soap. But have you ever thought that ordinary soap is one of the most ancient inventions of mankind? People had not yet invented spoons or forks, they did not know buttons, clocks, or window panes, and soap already existed. And this discovery is no less than 5 thousand years old. But the question of who should give the palm of the inventor, as always, is debatable.
Recipes for this first-ever detergent were found by archaeologists in ancient Egyptian papyri. And the famous Roman scientist and historian Pliny the Elder, who lived in the 1st century AD, in his "Natural History" argued that we owe the invention of soap to the enemies of Rome - the barbarians (Gauls and ancient Germans). It is difficult to say which of the listed peoples is the real author of soap.
Even in the paintings of the Flemish artists of the 17th century, images of children blowing soap bubbles through a clay straw were often found. In the 18th and 19th centuries, children blew soap bubbles using soapy water left over from washing. Bubble blowing gained even more popularity when, in 1886, the Pears Soap Company began advertising their "airy" product, using the famous painting "Bubbles" by John Milles (1829-1896). And the mass production of soap bubbles for sale began only in the 1940s.
Mystery 2: What is a soap bubble?
Soap bubble - a thin multilayered film of soapy water filled with air, usually in the form of a sphere with an iridescent surface. Soap bubbles usually last only a few seconds and burst when touched or spontaneously. Due to the fragility of the soap bubble has become synonymous with something attractive, but empty and short-lived.
In Ozhegov's dictionary, it is mentioned as something bright, but fragile, about an inflated size. About what quickly appears and quickly disappears.
Secret 3: Soap bubbles in painting.
Soap bubbles cannot leave anyone indifferent: neither an artist, nor a clown, nor a scientist, nor adults, nor children. We really liked Frances Tipton Hunter's painting Bubble Fairies. We also present works by other well-known artists.

Mystery 4: "Crystal balls".
Ordinary soap bubbles look amazingly beautiful on the street. Freezing in the cold, they turn into a kind of glass balls that decorate Christmas trees for the New Year. Such "crystal" beauties are obtained when the air temperature is below -7 ° C. Make a mixture: take melt water and dilute shampoo in it. It is better to blow out balloons from a plastic tube from a ballpoint pen or from a household funnel for pouring liquids. The balls are not at all fragile, if the ball falls, it will not break, only dents will appear on it. In light frost (from -3 to -7 ° C), the balls do not freeze, but you can try to conduct a small experiment. Try to carefully place a few snowflakes on the blown ball - they will immediately slide to the bottom of the bubble, and the crystallization process will begin at the place where the snowflakes are located. Soon you will see that the bubble is completely frozen. It will freeze even if you put it on the snow.
Secret 5: Different Ways to Make Bubbles
You can buy soap bubble solution at the store or make your own. Who among us has not translated shampoo bottles to blow soap bubbles? Did you succeed?
We don't have much. The bubbles, of course, inflated, but either burst immediately, before they had time to break away from the tip of the tube, or they still came off, but did not fly anywhere, but fell down and burst, not even having time to touch the ground. There was little joy from such bubbles. It turns out that in order to prepare the composition for soap bubbles, you need to know a few little tricks. About them, or rather about the recipes for the solution, we will now talk. So, how to make soap bubbles?
Experiment - testing the compositions of soap bubbles.
For this test, 10 recipes were selected.
Stage 1. For this experiment, the following substances were needed:
(all of them together or separately are the components of 10 recipes selected for the test)
- Water
- Dishwashing liquid
- Baby shampoo
- Washing powder
- Glycerin
- ammonia
- Polyvinyl alcohol
- Sugar
- Kettle (boiling water)
As well as:
jars
Various measuring containers
tubules
For convenience, we number the jars.
And of course, each of them relies on a tube for inflating bubbles, previously cut at the end.
Stage 2. We prepare 10 soap solutions according to recipes selected in the literature and the Internet.
Ingredients of 10 soap bubble recipes are given in the appendix
Some compositions at first glance are the same, but in such a delicate matter as a soap bubble, proportions can play a decisive role.
Stage 3. We test the composition of soap bubbles.
(of all the recipes, experiments with composition No. 8 can be considered incorrect, since it is according to the recipe, the composition must be infused for several days and filtered).
Test 1. Poke with a soapy finger.
To check the quality of the composition of soap bubbles, it must be pierced with a finger, after wetting it with the same soap solution, and if the bubble does not burst, then the composition is considered good.
However, all 10 soap formulations passed this test perfectly.
Test 2. For the lifetime of a soap bubble.
This test turned out to be the most interesting. 10 bubbles were blown out of 10 formulations.
Time has gone.
The bubbles from the 5th and 6th compositions were the first to give up, after a while the bubbles of the 8th, 9th, 10th and 3rd compositions burst. Then the 4th and 7th squads held out for a long time, but their bubbles also burst.
And now the real fight was formed between the 1st and 2nd teams.
After 30 minutes, it began to seem that these bubbles would last forever.
However, on the 35th minute, the 1st squad was blown away. That's right, pissed off! Because this bubble did not burst, but deflated for several seconds like an old balloon, eventually leaving not soapy water on the table, but a completely solid film.
And all this is because sugar was present in this composition in considerable proportions. The last bubble, composition number 2, lasted much longer than the others, as much as 50 minutes! It contained some sugar.
Conclusion: Sugar contributes to the longevity of soap bubbles.
Test 3. Blow bubbles.
As already mentioned, for blowing large soap bubbles, there are various special devices. But for the initial experiment, we take a regular cocktail straw. For each composition, several attempts are made to inflate the largest possible bubble. And I must say that many compositions showed very good results. It is also interesting that, for example, from composition No. 1, which lasted 30 minutes in the previous test, almost the smallest bubbles were obtained. And this means that the lifetime of the bubble is not the most important thing.
Soap bubbles of compositions win in this test: 2,7,8. They are followed by the compositions: 3 and 4. Then all the rest.
Thus, we can conclude: soap bubbles according to the second recipe turned out to be the most persistent and largest.
Mystery 6: Soap bubble and the Guinness Book of Records.
Look at this picture carefully. This is not Photoshop, not a visual effect. This is a soap bubble! A real soap bubble, except that it's just huge. Say it's impossible? But no, because in the USA and Great Britain they have long learned to produce equipment capable of blowing huge soap bubbles. 37-year-old London-based entrepreneur Samsam Bubbleman managed to create the biggest soap bubble in the world. His bubble measures 20 x 5 x 5 feet, is currently considered a champion, and therefore listed in the Guinness Book of Records. Bubbleman uses bubbles as promotions for his own company. To create something like this, you need special equipment, as I said above. You can't get by with an ordinary children's soap set.
He himself developed his own formulas for creating soapy water, in addition, he only works with his own equipment. The services of the entrepreneur are used by other firms and companies. The secret of creating giant soap bubbles, Mr. Bubbleman (or, to put it simply, Sam Hit) is kept in the strictest confidence.
Conclusion
By studying the literature and conducting experiments, we concluded that secret Making soap bubbles using liquid detergent, soap and water is very simple.
Water should be soft or, even better, distilled. Heavy water due to the mineral content will cause brittle blisters that will not last long. The easiest way to make water softer is to boil it well and let it stand. It is better to take warm water; soap dissolves faster in it.
The best soap for bubbles is simple household, domestic production. Bubbles from "Glycerine" or any liquid detergent are also good.
The lifespan of a bubble depends on how long it stays moist. Glycerin is great at slowing down drying time.
I would like to end my speech with Marshak's poems.
... Shining with a smooth film,
Stretching out,
Comes out tender, thin,
Colored bubble.
Inflated balloon takes off
More transparent than glass.
Inside it is like
Sparkling mirrors...
Thank you for your attention.
Will there be questions?
