Victoria Sakhna

In the article we have already told about some experiments in the kitchen. Today we will pay special attention to Moloka.

With this food product is familiar with each kid. And we will show the skin of milk to organism and methods for producing some dairy products. So today we will conduct the following experiments in the kitchen:

- creamy oil made of milk

- Production of cottage cheese

- Rubber bones

- Secret letter

Milk butter

To produce cream oil, we bought fatty homemade milk and left it overnight in the refrigerator. In the morning we saw how a more fatty part of milk - cream - rose upstairs. They are needed to obtain cream oil. We drag the cream into a clean bank and close it with a dense lid. If you buy milk in plastic bottles, then recover it immediately in the dishes with a wider neck. So the cream will merge much easier.

Now that all cookings are finished, we begin to shake the jar intensively. You can do it in turn with the child. He is such a guide, for sure, will like it. In the process, the shaking drop of fat will be knocked down together, and after 15 minutes, you will float a piece of butter on the surface.

We have turned out a piece of oil weighing 50 g, and we used it for sandwiches on the same day.

Production of cottage cheese

From the remaining milk we will make cottage cheese. We made cottage cheese in two stages using various ways to ensure milk.

Method 1. Heat the milk to 60 degrees and add 10% calcium gluconate at the rate of 5 ml at 0.5 l of milk. Show the baby, how milk begins to be desired and separated from the serum. We bring milk to a boil and filter through the gauze. We leave for a while so that cottage cheese is cooled, and with it the glass is all serum.

Using calcium gluconate, we get cottage cheese, additionally enriched with calcium.

Want to play with a child easily and with pleasure?

Method 2. It differs from the first use of citric acid or lemon juice for ensuring. Acid will suit any (food), since it is precisely it leads to the coagulation of milk protein. In general, the procedure remains the same.

In the household, such methods do not use such methods, since cottage cheese is made from the excess milk, which processed. But in this case there is one drawback. Bacteria that fall into milk randomly may be pathogenic and in case of insufficient thermal processing cause violation of the intestinal work. Therefore, if you want to get acidic cottage cheese, it is better to use special starts.

Our calcined cottage cheese has been coarse-grained and solid, while acidic - softer and fine-grained.

Surely, cottage cheese, made with mom, the kroch will eat with great pleasure regardless of the method of receipt. But how to clearly show the baby to the benefit of milk and dairy products? I propose to conduct the following experiment.

"Rubber" bones

We know that milk contains a lot of calcium, which in the body is used for the most part for the growth and strengthening of bones. What will happen to the bones if they are deprived of calcium?

So, we take the chicken bone, we rinse it well and clean me from the residues of meat and cartilage. We put it in the jar, fill with vinegar and leave for several days. After 3-4 days, the bone becomes "rubber", very flexible and soft. But the thing is that the vinegar was soluted by calcium contained in the bone.

Discuss with the baby, what will happen if you don't drink milk and there is no dairy products?

Secret letter

We continue to discuss the benefits of milk. It turns out that you can write secret messages with milk. Suggest the baby to pour with milk on a white sheet of paper. You can use both brush and wand. Give a secret message to dry and swing the hot iron. Invisible Earlier, the picture will manifest itself, since the milk under the action of high temperature will change its color to the light brown. The drawing will remain visible forever unlike.

These are so tasty and interesting. experiments in the kitchen We turned out.

And add to different porridge.
Porridge will not spoil exactly
White-yellow pieces.
Butter

What are you great! Quickly coped with the task !! All the answers found right!

Maybe someone guessed, and understood what we would talk about today? (About milk and dairy products)

What kind of dairy products, we have not yet told? (Kefir, yogurt, prokobvash, condensed milk, rippy, snowball, ... ..)

What milk dishes are cooking cooks for you in kindergarten? (Dairy soups, porridge, curved casserole, coffee drink, milk tea, lazy dumplings ...)

Main part.

Well done guys, all the riddles guess, responded to difficult questions.

And now the guys will tell you about the benefits of milk.

Milk gave us Mother Nature. Nature is arranged so that newborn children and animals are able and love to drink milk. (Slide 1 Child drinks maternal milk, kittens drink milk).

From early childhood Mom, their children begin to give different dairy products: cottage cheese, cream, kefir, sour cream, yogurt, cheese, oil ... (slide 2 photos with dairy products).

Where does milk come from? Who gives us? (Cows)

Knife adults and children

And know the entire planet

No more good in the morning -

Drink a cup of milk!

So that everyone is healthy

It gives us a cow!

And who else? (Goats ...)

It's no secret to anyone that milk gives us cows and goats. What are the cow's milk? (Cow) have a goat? (Goat)

There are other animals in the world that give milk. Maybe you know these animals? (Slide 3)

For example, a horse. From horse milk, a very useful drink is produced, which is called Koumiss. (Slide 3).

Camel milk - sweet, useful; Residents of Asian regions are very valued and loved. (Slide 4).

And where it is always cold, and there are problems with the delivery of fresh cow's milk, deer people. Northerners learned to make cheese, cottage cheese products from deer milk, oil. (Slide 4).

In children's nutrition, milk occupies a special place. Casserole, milk soup, porridge with butter, dumplings, pancakes, condensed milk with pancakes made on milk, and loved by all ice cream - all these children eat with pleasure. (Slide 5).

The most important component of milk is protein. If a person does not eat protein for a long time, it will not affect his health. There are vitamins, mineral and other nutrients in milk. (Slide 6).

Do not forget, children, about milk. Eat dairy products every day. The most valuable thing is that a person has his health.

Drink children milk - you will be healthy! (Slide 7).

Fizminutka

We are tired, dressed,

We wanted to warm up. (One hand up, other down, jerk change

Then the wall looked at the wall

Then the window was glanced.

Right, left turn

And then the opposite. (Cover Case.)

Naturally begin

Feet to the end bending.

Up and down, up and down

Nurse do not hurry! (Squats.)

And the last time sat down,

And now I sat on the chair. (Children sit down.)

In the laboratory, wonders I invite everyone I am! In it, we will give knowledge, with milk, we will be friendly!

Miracles with milk.

Experience 1. Secret ink.

Which of you know how to write a secret letter or a secret message?

Want to learn?

With what we write letters, draw? (Pens, Pencil, Paper ...)

Before used invisible ink. Under certain conditions, they became visible (heating, lighting)

Maybe someone guessed, what is this invisible ink? (Milk)

Want to write a secret message? Take the leaflets, cotton wands or tassels and with milk draw what you want. And I want to draw my heart, as I love you all.

Now it is necessary that our milk dried and become invisible. At the end of the lesson, we learn what secret messages you painted.

Experience 2. What is useful than Coca-Cola or Milk?

To visually see that we drink, and make the conclusion that we will have a good milk or coca-cola, we decided to mix the cola with milk. And that's what we did.

What is this me? (Milk and coca-cola)

What did we do yesterday? (They mixed)

What happened with us?

Conclusion: Milk darkened, it became brown, the reaction began, the milk came across, a sediment appeared in Wliwood. Koko-Cola took into an oxidative response with milk.

Experience 3. Experience with iodine.

In some plants, milk is diluted with water, and starch is added to the gifts. In this case, milk loses its useful properties.

And what should I do for this?

To do this, we will add iodine in our milk.

What happened to milk?

Conclusion: When connecting iodine with starch, a bright blue connection is formed.

Since our milk has not become blue, which means what conclusion will we do? (There is no starch in it)

Is it milk what? (Useful)

Experience 4. "Boiling milk"

Is there an expression "Milk I have convinced" the milk have legs? (Not)

Why so they say?

Milk "runs away" when boiling, it rises up, and if you do not remove from the stove on time with a stove, a piece of milk from it simply runs out.

Want to see how milk runs? We have no slab, there is no fire, pans to boil milk.

But, we have a scientific laboratory of miracles.

For our experience, lemon acid, soda and milk will need.

Add to milk add soda what is happening? And now add citric acid.

See what happens to milk? (It foams, boils)

Conclusion: The soda and citric acid reaction occurs in milk. It foams, highlights bubbles, boils.

Experience 5 "Color Milk"

Guys do you like to draw? What do you draw on? (On leaves, in albums, in the snow, sand, on asphalt ...)

What do you usually draw? (Paints, pencils, markers, wand, crayons ...)

And on milk someone from you painted? (Not)

Want to try?

On the tables stands milk in plates. Add a few drops of green, red, blue paint (pipette, tassel or cotton stick).

Take another cotton wand, plunge it into a liquid soap. A wand dipped in dishwashing liquids, concern milk for literally 10 seconds. Just touch!

And then the most interesting begins - the magic paints begin to "dance", breaking away from the cotton wand. From the magic cotton wand and from the colored explosion in milk. When the wand cleaned - the paints continue to "dance", move. Milk begins to move, and paint stir. Real salute in a plate!

Conclusion: we see the explosion of paints. The liquid soap reacts with milk and causes paints to move, it repels fat connecting in milk. That is why skim milk is not suitable for experience.

See what I have? (Rag and Iron)

What need to do? (To try our letter)

Conclusion: Some substances that are contained in milk, under the action of heat are destroyed faster than the paper itself lights up. With this chemical process, combustion products are highlighted. When brewing milk spots on paper, proteins and carbohydrates are charred and become visible.

What did I write to you in my letter?

Reflection.

Who liked today's experiments, experiments?

Who wants with parents, try, show what miracles do we do with you today?

What product did we say today?

What conclusion about it can you do?

Drink children milk - you will be healthy!

Surprise moment: Showing the cartoon "Smeshariki-Dairy Paris"

A small child is not only an eternal engine and a jumper, but also a brilliant fifteentist and infinite intelligence. Children's curiosity, though it gives parents a lot of worries, but in itself very useful - this is the key to the development of the baby. Recognize something new is useful not only in the form of lessons, but also in the form of game or experiments. It is about them today and let's talk. Simple physical and chemical experiments do not require special knowledge, special training or expensive materials. They can be carried out in the kitchen to surprise, entertain the child, open the whole world in front of him or just raise the mood. Almost any experience, the child can prepare and deliver independently in your presence. However, in some of the experiments, the main acting person is better to make mom or dad.

Complex color in milk

What can be amazing than turning the usual thing in unusual when white, familiar to everyone becomes multicolored milk?

It will take: whole milk (required!), Food dyes of different colors, any liquid detergent, cotton wands, plate.
Work plan:

Pour milk into a plate.
Add a few drops of each dye to it. Try to do it carefully not to move the plate itself.
Take a cotton wand, plunge it into the remedy and touch it in the very center of plates with milk.
Milk will start moving, and the colors to mix. True color explosion in a plate!

Explanation of experience: Milk consists of different types of molecules: fats, proteins, carbohydrates, vitamins and minerals. When adding a detergent to milk, several processes occur simultaneously. First, the detergent reduces the surface tension, and due to this, food dyes begin to move freely throughout the surface of milk. But the most important thing is that the detergent reacts with fat molecules in milk and leads them in motion. That is why skimmed milk is not suitable for this experience.

We grow crystals

This experience everyone knows from childhood - obtaining crystals from salt water. You can, of course, do it with a copper sulfate solution, but a children's option is a simple cooking salt.

The essence of the experiment is simple - in a salty solution (18 spoons of salt on the floor of the liter of water) omit the color thread and we are waiting for the crystals on it. It will be very interesting. Especially if you take a woolen thread or replace it with an intricate bristle wire.

Potatoes becomes a submarine

Did your child have already learned to clean and cut potatoes? His will no longer surprise this gray-brown tuber? Of course, surprise! You need to turn potatoes into a submarine!
To do this, we need one potato tube, a liter bank and food salt. Pour half a breaker and lower the potatoes. She drowshes. Add a saturated salt solution to the bank. Potatoes will pop up. If you want it to plunge into the water again, then add water to the jar. Well, what is not a submarine?
Riprage: Potatoes Suns, because It is heavier than water. Compared with salt solution, it is easier, therefore it floats to the surface.

Battery from lemon.

To spend this experience well with dad so that he explained in more detail, where in Lemon electricity?

We will need:

Lemon, thoroughly washed and wiped dry.
Two pieces of copper insulated wire approximately 0.2-0.5 mm thick and 10 cm long.
Steel paper clips.
Light bulb from a pocket lantern.

Experience:first of all, we clean the opposite ends of both wires at a distance of 2-3 cm. We insert into lemon clips, screw the end of one of the wires to it. We stick into a lemon at 1-1.5 cm. From the clips end of the second wire. To do this, first singe a lemon in this place needle. Take two free end of the wires and apply to the contacts of the light bulb.
What happened? Light bulb caught fire!

A glass of laughter

Do you need to urgently do soup, and the child hangs on the legs and pulls into the nursery? This experience will make him distract for a few minutes!
We need only a glass with thin smooth walls, filled with top water.
Experience: Take the glass in your hand and bring to the eyes. Look through it on the fingers of another hand. What happened?
In the glass you will see very long and thin fingers without a brush. Turn the hand to your fingers up, and they will turn into a funny brief. Create a glass away from the eye, and the whole brush will appear in the glass, but small and on the side, as if you move your hand.
Look with a child on each other through the glass - and do not go to the room of laughter.

Water flows up napkin

It is a very beautiful experience perfect for girls. We need to take a napkin, cut striped, draw dots line of different colors. Then we lower the napkin into a glass with a small amount of water and admiringly observe how water rises and dotted lines turn into solid.

Tea Package Miracle Rocket

This elementary focus experience is just a "bomb" for any child. If you have already tortured to look for brilliant entertainment for children, this is what you need!

Carefully discover the usual tea bag, put it vertically and install it. Package Dogrite to the end, takes off high in the air and will circle over you. This simple experiment usually causes a storm of enthusias and in adults, and in children. And the reason for this phenomenon is the same that makes the sparks from the fire. During burning, a stream of warm air is created, which pushes the ashes up. If you get up and stew the bag gradually, no flight will turn out. By the way, the bag will not always take off if the air temperature is high enough.

Living fish

Another simple experience that can be pleasantly surprised not only by children, but also girlfriends.
Cut from thick paper fish. In the middle of the fish, the rice hole A, which is connected to the tail of the narrow channel of the AB.

Pour the water in the pelvis and put the fish on the water so that the bottom side of it all is moistened, and the upper remains completely dry. It is convenient to do this with a fork: putting the fish on the plug, carefully lower it on the water, and the plug is drunk deep and pull out.
Now you need to drop into the hole and a large drop of oil. It is best to take advantage of this with a bike or sewing machine. If there are no masks, you can dial machine or vegetable oil into a pipette or a tube from a cocktail: lower the tube with one end to the oil by 2-3 mm. Then the top end cover with your finger and move the straw to the fish. Holding the bottom end exactly above the hole, release the finger. The oil is flowing directly into the hole.
In an effort to break through the surface of the water, the oil flows through the ab. Raced on other parties will not give him a fish. Do you think that will make the fish under the action of oil flowing back? Clear: she sails forward!

Focus "Conspiracy of Water"

Each child believes that his mother is a wizard! And in order to extend the longer this fairy tale, it is sometimes necessary to reinforce your magic nature with real "magicians".
Take the jar with a tightly spinning lid. The inner side of the cover is painted with red watercolor paint. Pour water into the jar and tighten it with a lid. At the time of the demonstration, do not turn the bank to small viewers so that the inside side of the lid is visible. Slide the conspiracy loudly: "In exactly the way, in a fairy tale, become a cloth with red." With these words, shake the jar with water. Water will wash the watercolor paint layer and will become red.

Tower density

Such an experiment will fit older children, or attentive, perfected kids.
In this experience, items will depend in the thickness of the fluid.
We will need:

high narrow glass vessel, for example, empty pure half-liter can from under canned olives or mushrooms
1/4 cup (65 ml) corn syrup or honey
food dye of any color
1/4 cup of tap water
1/4 glasses of vegetable oil
1/4 medical alcohol
different Minor Items, for example, Cork, Grape, Walnut, Slice Dry Makaronin, Rubber Ball, Tomatour "Cherry", Little Plastic Toy, Metal Screw

Preparation:

Gently pour honey into the vessel, so that it occupies 1/4 volume.
Dissolve several drops of food dye in water. Pour water into the vessel to half. Please note: adding each liquid, Leite is very careful so that it does not mix with the lower layer.
Slowly pour the same amount of vegetable oil into the vessel.
Different vessel to the top alcohol.

We begin scientific magic:

Announce the audience that now forced different items to swim. You may say that it is easy. Then explain to them what makes different items in floating in liquids at different levels.
One manner is neatly lowering small objects into the vessel.
Let the audience themselves see what happened.

Result: different items will swim in the thickness of the liquid at different levels. Some "hang" right in the middle of the vessel.
Explanation: This trick is based on the ability of various substances to sink or float depending on their density. Substances with a smaller density float on the surface of more dense substances.
The alcohol remains on the surface of the vegetable oil, because the density of the alcohol is less than the density of the oil. Vegetable oil remains on the surface of water, because the oil density is less than the density of water. In turn, the water is a substance less dense than honey or corn syrup, so it remains on the surface of these liquids. When you lower items into a vessel, they are floating or drown depending on their density and density of fluid layers. Shurupa has a density higher than any of the liquids in the vessel, so it will fall on the very bottom. Macaronly density is higher than the density of alcohol, vegetable oil and water, but lower than honey density, so it will float on the surface of the honey layer. The rubber ball has the smallest density, lower than any of the liquid, so it will float on the surface of the highest, alcohol, layer.

Grape submarine

Another trick for marine adventure lovers!

Take a glass with fresh carbonated water or lemonade and throw a grape into it. It is a little harder water and drops to the bottom. But it will immediately begin to sit by gas bubbles, similar to small balloons. Soon there will be so many that the grape will pop up. But on the surface bubbles burst, and gas will fly away. The rebeling grape again falls on the bottom. Here it will be covered by gas bubbles and will pop up again. So it will continue several times until the water is "exhausted." According to this principle, the real boat pops up and rises. And the fish have a swimming bubble. When she needs to plunge, the muscles are compressed, squeeze the bubble. Its volume decreases, the fish goes down. And you need to rise - the muscles relax, the bubble is blown. It increases, and the fish pops up.

Lotus flowers

Another experiment from the series "For Girls".
Cut out color paper flowers with long petals. With a pencil, tighten the petals to the center. And now lower the multicolored lotuses on the water, poured into the pelvis. Literally on your eyes, flower petals will be blown away. This is because the paper wets, it becomes gradually harder and the petals are revealed.

Where to share ink?

You can put the next focus to the mother-wizard's piggy bank.
In an ink or carcass in a water bubble, so that the solution was pale blue. Put the tablet of extended activated carbon. Close the neck with a finger and shake the mixture. She brightens in front of her eyes. The fact is that coal absorbs his surface of the dye molecule and is no longer visible.

"Stop, hands up!"

And this experience is again for boys - explosive and playful fidgets!
Take a small plastic jar from under medication, vitamins, etc. Pill in it some water, put any hip tablet and close it with a lid (independent).
Put it on the table by turning upside down, and wait. The gas, isolated during the chemical reaction of pills and water, will push the bottle, the "roar" and the bottle will throw up the bottle.

Secret letter

Each of us dreamed of every time in life to turn into a detective or secret agent. It's so fascinating - to solve riddles, search for traces and see invisible.

Let the child on a clean sheet of white paper make a drawing or inscription with milk, lemon juice or cutlery vinegar. Then heep a sheet of paper (better above the device without open fire) and you will see how invisible turns into visible. Improvised ink will boil, letters will darken, and the secret letter can be read.

Scattering toothpicks

If there is nothing in the kitchen to do, and from available toys only toothpicks, then we will easily let them in the case!

To carry out experience, you will need: a bowl with water, 8 wooden toothpicks, a pipette, a piece of sugar-raffinad (not instant), dishwashing liquid.
1. We have toothpicks with rays in a bowl with water.
2. The bowl of the bowl gently omit a piece of sugar, - the toothpicks will start going to the center.
3. We remove sugar with a teaspoon and dripping a pipette into the center of the bowl of a few drops of liquid for washing dishes, - toothpicks "scatter"!
What is happening? Sugar sucks water, creating its movement moving toothpicks to the center. Soap, spreading along the water, carries out particles of water, and they force the toothpicks to scatter. Explain to children that you showed them focus, and all the focuses are based on certain natural physical phenomena that they will study at school.

Disappearing coin

And this focus you can teach any child older than 5 years, let him show him his friends!
Props:

glass jar with lid capacity 1 liter
water water
coin
assistant

Preparation:

Pour into the water bank and close the lid.
Give your assistant coin so that he can make sure that it is really the most common coin and there is no trick in it.
Let him put a coin on the table. Ask him: "Do you see a coin?" (Of course, he will answer "yes.")
Put the jar with water on the coin.
Tell the magic words, for example: "Here's a magic coin, it was, but there is no".
Let your assistant look through the water from the side of the bank and say, does he sees the coin now? What will he answer?

Tips to a scientist wizard:
You can make this trick even more spectacular. After your assistant can see the coin, you can make it appear again. Tell me other magic words, for example: "as a coin failed, so it appeared." Now remove the jar, and the coin will turn out again in place.
Result: When you put a jar on a coin with water, it seems that the coin disappeared. Your assistant will not see her.

Guys, we put the soul in the site. So
what you open this beauty. Thanks for inspiration and goosebumps.

Everyone knows that anyone, even the most amazing experience can be explained. Let so, but admiration and delight of children do not decrease from this. And adults are also rejoicing, making small discoveries along with the kids.

website I picked up for you eight stunning experiments, from which he will capture the spirit and in children, and in adults. We are confident: from what you understand everything, they will not be boring.

Egg in a bottle

Need: Egg, bottle with neck diameter less than an egg, a thin strip of paper and a droplet of vegetable oil.

Experience: Is it possible to put an egg in a bottle without breaking neither a bottle, no eggs? It is possible if it is quail. But we will try to do it with usual. For this, the egg weld the egg and clean it from the shell. Lubricate the neck of the bottle with vegetable oil. Google paper and throw it on the bottom of the bottle, and then immediately put an egg on the neck. When the paper goes out, the egg is sad inward.

What's happening: The fire burns in a bottle of oxygen and firing air is formed in it. The reduced pressure from the inside and the usual atmospheric pressure outside act together and pushed the egg into the bottle. Due to its elasticity, it slips through a narrow neck.

Cola and Menthos Fountain

Need: Two-liter bottle of dietary COCA COLA and 5-6 Mentos dragee.

Experience: In order not to pour a stake on the whole house, it is best to spend this experiment on the street. The Mentos dragee should get into the bottle at the same time, because the reaction begins almost instantly. To do this, they can be put on a spotted groove with a piece of paper and give to slip into a bottle, and even better - to put on a thread one by one and once to omit in the cola. Another important point is to try to jump out the express time so as not to please under the sweet fountain.

What's happening: The rough surface of the dragee causes carbon dioxide dissolved in the drink, actively released. Cola sharply foams, and with force pulling out of the bottle, forms a fountain.

Elephant Toothpaste

Need: Plastic bottle, tray, dry yeast, 6% hydrogen peroxide, food dye, liquid soap or dishwashing liquid, water.

Experience: Put a bottle on the tray. Fill in it half a compound of hydrogen peroxide, add a bit of soap or detergent and do not regret the food dye. Separately in the cup, thoroughly mix 2 tablespoons of warm water and 1 teaspoon of yeast (work on this not less than a minute), and then pour the mixture into the bottle. Almost immediately, color foam resembling a toothpaste, which is squeezed out of a huge tube.

What's happening: Hydrogen peroxide disintegrates on water and oxygen, and yeast as a catalyst accelerates the reaction. Soap contributes, multiplying bubbles. By the way, the bottle and the "toothpaste" are warm up - during the reaction heat is allocated.

Chubby paints

Need: Dry flour, small salt, water, food dyes or gouache, cotton wands or thick brush, dense paper drawing.

Experience: To make the paint of the same color, you need to mix in a cup of 1 tablespoon of flour and 1 tablespoon of salt, and then add three tablespoons of water and paint there. In the same way, prepare paints of other colors. Draw better on dense paper or cardboard with cotton wand or thick tassel (for each color, use separate). After the drawing is ready, "bake" it in the microwave - it will be enough to 4-5 minutes at a capacity of 600 W. During this time, the paints will be bludging and hardening and the drawing will become volumetric.

What's happening: Our paint, in fact, is the usual dough, only color, so it rises in the microwave.

Icemies: Krasim ice from inside

Need: Molds for ice (any cups and bowls are also suitable), a tray with sides, salt, liquid food dyes or paints, pipettes or teaspoons.

Experience: In advance, from the evening, frozen more ice in big and small molds. The next day, prepare strong salt solutions in several tanks and add paint there. Spread the ice figures on a tray, and a pipette or teaspoon drip salt solutions on them. Salt will melt the ice, "trying" in it in it, and the paint will paint from the inside the bizarre patterns.

What's happening: When sodium in salt comes into contact with ice, a reaction occurs with heat isolation, which causes ice to melt. That is why the ice is sprinkled with a mixture of sand and salt.

Homemade rain

Need: Large transparent capacity (bank, salad bowl), water, shaving foam, pipette or teaspoon, liquid food dye. Instead of dye, you can take a gouache or watercolor and breed them in water.

Experience: Pour water into the container and squeeze into it lush clouds from foam. Then drip a pipette or a teaspoon on a foam in different places a few drops of the dye and wait - the rain will soon go from the clouds.
