Entertaining experiences in kitchen of

we Do cottage cheese

of the Grandmother which are more than 50 years old, well remember how did cottage cheese to the children. You can show this process and to the child. Warm up milk, having poured in it in a little juice of a lemon (it is possible to use also chloride calcium). Show to children as milk at once turned big flakes, and over it there is a serum.

Merge the received weight through several layers of a gauze and leave on 2 - 3 hours. At you turned out fine cottage cheese. Water it with syrup and offer the child for dinner. Are sure, even those children who do not love this dairy product, will not be able to refuse the delicacy prepared with their own participation.

How to make ice cream? to you it is required by

For ice cream to h2: cocoa, sugar, milk, sour cream. It is possible to add to it some grated chocolate, wafer crumbs or small pieces of cookies. Stir two tablespoons of cocoa, one tablespoon of sugar, four tablespoons of milk and two tablespoons of sour cream in a pan. Add a crumb of cookies and chocolate. Ice cream is ready. Now it should be cooled. Take a bowl more, put in it ice, salt it, mix. On ice put a pan with ice cream and from above cover with a towel that heat did not get into it. Each 3 - 5 minutes stir slowly ice cream. If you have enough patience, then in some 30 minutes ice cream will thicken and it can be tried. Tasty?


As our self-made refrigerator works? It is known that ice thaws at a temperature of zero degrees. Salt detains cold, does not allow ice to thaw quickly. Therefore salty ice keeps cold longer. Moreover the towel does not allow to get to warm air to ice cream. And result? Ice cream is higher than any praises!

we Will churn butter

If you live in the summer in the country, then for certain take genuine milk from the milkwoman. Do together with children experiences with milk. Prepare a one-liter jar. Fill it with milk and put on 2 - 3 day in the refrigerator. Show to children as milk was stratified on easier cream and the heavy “removed“ milk. Collect cream in bank with a tight cover. And if you have a patience and free time, then shake to bank within half an hour in turn with children until balls of fat merge together and do not form oil lumps. Believe, children never ate such tasty oil.

Home-made lollipops

Cookery - fascinating occupation. Now we will make home-made lollipops. For this purpose it is necessary to prepare a glass with warm water in which to dissolve so much granulated sugar how many it can be dissolved. Then take a straw for cocktail, tie to it a pure thread, having fixed a small piece of macaroni on its end (it is the best of all to use small pasta). Now it was necessary to put a straw from above of a glass, across, and with makaroniny to lower the end of a thread in sugar solution. And to have patience.

When water from a glass will begin to evaporate, molecules of sugar will begin to approach and sweet crystals will begin to settle on a thread and on the makaronena, taking bizzare shapes. Let your kid will taste lollipop. Tasty? The same lollipops will be much more tasty if to add syrup from jam to sugar solution. Then lollipops with different taste will turn out: cherry, blackcurrant and others what he will want.

“Fried“ sugar


two pieces of refined sugar. Moisten them with several drops of water that it became damp, put in a spoon from stainless steel and heat it several minutes over gas until sugar thaws and will turn yellow. Do not allow it to burn slightly. As soon as sugar turns into yellowish liquid, pour out spoon contents on a saucer small drops. Taste the candies with children. It was pleasant? Then open confectionery!

we Change color of cabbage

Make thinly chopped red cabbage salad together with the child, ground with salt, and water it with vinegar with sugar. Observe how the cabbage from violet will turn in brightly - red. This influence of acetic acid. However in process of storage salad can become violet again or even to turn blue. There is it because gradually acetic acid is diluted with cabbage juice, its concentration goes down and coloring of dye of a red cabbage changes. There are such transformations.

Why unripe apples sour?

Unripe apples contain a lot of starch and do not contain sugar. Starch - substance unsweetened. Let`s the child lick starch, and he will be convinced of it. How to learn that the product contains starch? Make rather weak solution of iodine. Drip them in a handful of flour, starch, on a piece of crude potatoes, on a segment of unripe apple. The appeared blue coloring proves that all these products contain starch. Repeat experiment with apple when it completely ripens. And, probably, will surprise you that you will not find starch in apple any more. But now in it sugar appeared. Means, maturing of fruits is a chemical process of transformation of starch into sugar.

Edible glue

to your child was necessary for

for hand-made articles glue, and the jar with glue turned out empty? You do not hurry in shop behind purchase. Weld it. What is habitual for you - is unusual to the child.

Weld to it a small portion of dense kissel, showing it each of process stages. For those who do not know: in the boiling juice (or in water with jam) it is necessary to pour, carefully mixing, solution of the starch divorced in a small amount of cold water and to bring to boiling. I think, the child will be surprised that this glue - kissel can be eaten with a spoon, and they can stick together hand-made articles.

House sparkling water


to the child that he breathes air. Air consists of different gases, but many of them are invisible and have no smell therefore it is difficult to find them. Carbon dioxide - one of the gases which are a part of air and... sparkling water. But it can be allocated in house conditions.


two straws for cocktail, but different diameter so that narrow on several millimeters densely entered wider. The long straw made of two turned out. Do in a stopper of a plastic bottle a sharp object a through vertical opening and insert any end of a straw there. If there are no straws of different diameter, then it is possible to make in one a small vertical cut and to thrust it in other straw. The main thing that dense connection turned out.


in a glass of the water diluted with any jam, and in a bottle through a funnel fill a half of a tablespoon of soda. Then pour in a bottle vinegar - about hundred milliliters. Now it is necessary to work very quickly: thrust a stopper with a straw in a bottle, and lower other end of a straw in a glass with sweet water. What occurs in a glass? Explain to the child that vinegar and baking soda actively began to interact with each other, allocating vials of carbon dioxide. It rises up and on a straw passes in a glass with drink where comes to a water surface bubbles. Here sparkling water is also ready.


and eat

Properly wash up two oranges. Put one of them in a bowl with water. He will swim. And even if very much to try, it will not be possible to drown it. Peel the second orange and put it in water. Well that? You do not trust the eyes? Orange drowned. How so? Two identical oranges, but one drowned, and the second swims? Explain to the child:“ In an orange peel there are many vials of air. They push out orange on a water surface. Without peel orange sinks because it is heavier than water which forces out“.

About advantage of milk

Strangely enough, but we know all better why it is necessary to drink milk, having done experiment with bones. Take the eaten-around chicken stones, wash them properly, let`s them dry. Then fill in in a pan with vinegar that it covered stones completely, close a cover and leave for a week. In seven days merge vinegar, attentively consider and touch bones. They became flexible. Why? It appears, fortress gives to bones calcium. Calcium in acetic acid is dissolved, and bones lose hardness.

you Want to ask

: “What does it have to do with milk?“ It is known that in milk there is a lot of calcium. Milk is useful because fills up our organism with calcium, so, does our bones firm and strong.

As from salty water to extract drinking water?


together with the child in a deep basin of water, add two tablespoons of salt there, mix until salt is dissolved. On a bottom of an empty plastic glass put the washed-out pebble that it did not emerge, but its edges have to be above water level in a basin. From above pull a film, having tied it around a basin. Press through a film in the center over a glass and put one more stone in deepening. Put a basin on the sun. In several hours in a glass unsalted, clear drinking water will collect. It speaks simply: water on the sun begins to evaporate, condensate accumulates on a film and flows down in an empty glass. Salt does not evaporate and remains in a basin. Now, when you know how to extract fresh water, it is possible to go quietly to the sea and not to be afraid of thirst. There is a lot of water in the sea, and from it it is always possible to receive the purest drinking water.

Live yeast

the Known Russian proverb says:“ The log hut is red not corners, but pies“. We will not bake pies, however. Though why is not present? Especially as we in kitchen have yeast always. But before we will show experience, and then it is possible to undertake also pies. Tell children that yeast consists of the tiny live organisms called by microbes (and it means that microbes happen not only harmful, but also useful). Eating, they emit carbon dioxide which, mixing up with flour, sugar and water, “lifts“ dough, does it magnificent and tasty.

Dry yeast is similar

to small lifeless balls. But it only until millions of tiny microbes which doze in a cold and dry look recover. Let`s them recover. Pour two tablespoons of warm water in a jug, add to it two teaspoons of yeast, then one teaspoon of sugar and mix. Pour out barmy mix in a bottle, having pulled a balloon on its neck. Put a bottle in a bowl with warm water. Ask children what will occur? It is correct when yeast recovers and will begin to eat sugar, mix will be filled with vials of carbon dioxide already familiar to children which they begin to emit. Bubbles burst, and gas inflates a ball. whether

is Heated by a fur coat?

This experience has to be pleasant to children very much. Buy two glasses of ice cream in a paper wrapper. Develop one of them and put on a saucer. And directly in a wrapper wrap the second in a pure towel and properly wrap up with a fur coat. In about 30 minutes develop the wrapped-up ice cream and lay out it without wrapper on a saucer. Develop also the second ice cream. Compare both portions. Are surprised? And your children?

It appears p, ice cream under a fur coat, unlike what on a silver platter, almost did not thaw. So? Perhaps a fur coat - at all not a fur coat, but the refrigerator? Why then we put on it in the winter if it does not heat, and cools? Everything speaks simply. The fur coat ceased to pass room heat to ice cream. And from it to ice cream in a fur coat it became cold, here ice cream also did not thaw.

also the question is natural

Now: “Why the person in a frost puts on a fur coat?“ Answer:“ Not to freeze“. When the person of the house puts on a fur coat, to it is warm, and the fur coat does not let out heat on the street, here the person also does not freeze.

Ask the child whether he knows that there are “fur coats“ from glass? It is a thermos. It has double walls, and between them - emptiness. Warmly badly passes through emptiness. Therefore when we in a thermos give hot some tea, it long remains hot. And if to pour in it cold water what will happen to it? The child can answer this question now. If with the answer he still is at a loss, let will do one more experience: will pour in a thermos of cold water and will check it in about 30 minutes. whether

the Persistent funnel

Can “refuse“ to pass a funnel water in a bottle? Let`s check! It will be necessary for us: 2 funnels, two identical pure dry plastic bottles on 1 liter, plasticine, a jug with water.


  1. into each bottle on a funnel.
  2. Cover a neck of one of bottles around a funnel with plasticine that there is no crack left.

It is begun scientific magic!


to the audience: “I have a magic funnel which does not start up water in a bottle“.


a bottle without plasticine and pour in it through a funnel a little water. Explain to the audience:“ Here so the majority of funnels behaves“.

Deliver to

on a table a bottle with plasticine. Pour in a water funnel to top. Look what will be.

Result. From a funnel in a bottle a little water will leak, and then it will stop flowing absolutely.


In the first bottle water flows freely. The water flowing through a funnel in a bottle replaces in it air which comes out through cracks between a neck and a funnel. In the bottle sealed by plasticine there is too an air which has the pressure. Water in a funnel has too pressure which arises thanks to the gravity pulling water down. However air pressure force in a bottle exceeds the gravity operating on water. Therefore water cannot get to a bottle.

If in a bottle or in plasticine at least, air will be able to come out through it. From - for it its pressure in a bottle will fall, and water will be able to flow in it.

the Dancing flakes

Some grain is capable to make a lot of noise. Now we learn and whether it is possible to teach rice flakes also to jump and dance. to us it will be necessary for

of p:


  1. Spread a paper towel on a table.
  2. Pour out flakes on a towel.
we Begin with

scientific magic!

  1. Address the audience so:“ All of you, of course, know how rice flakes can crack, crackle and rustle. And now I will show you as they are able to jump and dance“.
  2. Inflate with
  3. a ball and tie it.
  4. Rub a ball about a woolen sweater.
  5. Bring a ball to flakes and look what will occur.

Result. Flakes will jump up and be attracted to a ball.

Explanation. With this experiment to you is helped by static electricity. Electricity call static when current, that is movement of a charge, no. It is formed due to friction of objects, in this case a ball and a sweater. All objects consist of atoms, and is in each atom equally protons and electrons. At protons a charge positive, and at electrons - negative. When these charges are equal, a subject call neutral, or not loaded. But there are objects, - for example, hair or wool, - which very easily lose the electrons. If to rub a ball about a woolen thing, the part of electrons will pass from wool to a ball, and it will get a negative static charge.

When you bring closer a negatively charged ball to flakes, electrons in them begin to make a start from it and to move to the opposite side. Thus, the top party of flakes turned to a ball becomes loaded positively, and the ball attracts them to itself.

If to wait longer, electrons will begin to pass with a ball to flakes. Gradually the ball will become neutral again, and will cease to attract flakes. They will fall back to a table.


As you think whether it is possible to divide the mixed pepper and salt? If you master this experiment, then you will precisely cope with this difficult task! to us it will be necessary for

of p:


  1. Spread a paper towel on a table.
  2. Fill on it salt and pepper.

It is begun scientific magic!

Suggest someone from the audience to become
  1. your assistant.
  2. Carefully mix a spoon salt and pepper. Suggest the assistant to try to separate salt from pepper.
  3. When your assistant will despair them to divide, suggest it to sit and look now.
  4. Inflate with
  5. a ball, tie and rub them about a woolen sweater.
  6. Bring a ball closer to mix of salt and pepper. What will you see?

Result. Pepper will stick to a ball, and salt will remain on a table.

Explanation. It is one more example of action of static electricity. When you rub a ball woolen fabric, it gets a negative charge. If to bring a ball to pepper mix with salt, pepper will begin to be attracted to it. It occurs because electrons in peppery motes seek to move as it is possible further from a ball. Therefore, part a perchinok, the next to a ball, gets a positive charge, and is attracted by a negative charge of a ball. Pepper sticks to a ball.

Salt is not attracted by

to a ball as in this substance electrons move badly. When you bring the loaded ball to salt, its electrons all the same remain on the places. Salt from a ball does not get a charge - remains not loaded or neutral. Therefore salt does not stick to a negatively charged ball.

Flexible water

In the previous experiences you by means of static electricity learned to dance flakes and separated pepper from salt. From this experience you learn how the static electricity affects ordinary water. to us it will be necessary for

of p:



For carrying out experience choose the place where you will have an access to a water supply system. The kitchen perfectly will approach.


It is begun scientific magic!

  1. to the audience:“ Now you will see how my magic will operate water“.
  2. Open the crane that water flew a thin stream.
  3. Tell
  4. magic words, urging a stream of water to move. Nothing will change; then apologize and explain to the audience that you should use the help of the magic ball and a magic sweater.
  5. Inflate with
  6. a ball and tie it. Rub a ball about a sweater.
  7. pronounce magic words Again, and then bring a ball to a water stream. What will occur?

Result. the Stream of water will deviate towards a ball.

Explanation. Electrons from a sweater at friction pass to a ball and give it a negative charge. This charge pushes away from itself the electrons which are in water, and they move to that part of a stream which is the farthest from a ball. Closer to a ball in a stream of water there is a positive charge, and the negatively charged ball pulls it to itself.

That movement of a stream was visible, it has to be small. The static electricity accumulating on a ball is, not enough, and to move not in power to it a large amount of water. If the stream of water concerns a ball, it will lose the charge. Excess electrons will pass into water; both the ball, and water will become electrically neutral therefore the stream will begin to flow exactly again.
