The Ghostbusters remake is coming out very soon, and this is a great excuse to rewatch the old film and study non-Newtonian fluids. One of the heroes of the film, the stupid ghost Lizun, - good image for visualization. This is a character who loves to eat, and he can also penetrate walls.

We will need:

• potato,
• tonic.

What we do

Cut the potatoes very finely (can be chopped in a food processor) and pour hot water. After 10-15 minutes, drain the water through a sieve into a clean bowl and set aside. A sediment will appear at the bottom - starch. Drain the water; the starch will remain in the bowl. In principle, you will already have a non-Newtonian fluid. You can play with it and watch how it hardens under your hands and becomes liquid on its own. You can also add food coloring for bright color.

Now let's add a little magic.

The starch needs to be dried (leaved for a couple of days). And then add tonic to it and make a kind of dough that is easy to pick up. It will retain its consistency in your palms, but if you stop and stop kneading it, it will begin to spread.

If you enable ultraviolet lamp, then you and your child will see how the dough begins to glow. This is due to the quinine found in tonic water. It looks magical: a glowing substance that behaves as if it violates all the laws of physics.

2. Get superpowers

Comic book heroes are especially popular now, so your child will love feeling like the powerful Magneto, who can control metals.

We will need:

• printer toner,
• magnet,
• vegetable oil.

What we do

From the very beginning, be prepared for the fact that after this experiment you will need a lot of napkins or rags - it will be quite dirty.

In no large capacity add about 50 ml of toner for laser printers. Add two tablespoons vegetable oil and mix very well. Done - you have in your hands a liquid that will react to a magnet.

You can attach a magnet to the container and watch how the liquid literally sticks to the wall, forming a funny “hedgehog”. It will be even more interesting if you find a board on which you don’t mind pouring a little black mixture, and invite your child to use a magnet to control the drop of toner.

3. Turn milk into a cow

Invite your child to turn liquid into solid without resorting to freezing. This is a very simple and impressive experience, although you will have to wait a couple of days to get the results. But what an effect!

We will need:

• cup ,
• vinegar.

What we do

Heat a glass of milk in microwave oven or on the stove. We don't boil. Then you need to add a tablespoon of vinegar to it. Now let's start stirring things up. Actively move the spoon in the glass to see white clots appear. This is casein, a protein found in milk.

When there are a lot of clots, drain the mixture through a sieve. Whatever remains in the colander needs to be shaken, then placed on a paper towel and dried a little. Then start kneading the material with your hands. It will look like dough or clay. At this stage, you can add food coloring or glitter to make the white mass brighter and more interesting for your baby.

Invite your child to make something from this material - a figurine of an animal (for example, a cow) or some other object. But you can just put the mass in plastic mold. Leave to dry for a day or two.

When the mass dries, you will have a figurine made of very hard hypoallergenic material. This type of “homemade plastic” was used until the 1930s. Casein was used to make jewelry, accessories, and buttons.

4. Control snakes

Getting vinegar and baking soda to react is just about the most boring experience imaginable. “Volcanoes” and “fizzy drinks” will not be of interest to modern children. But you can invite your child to become a “snake lord” and show how acid and alkali actually react.

We will need:

• pack of gummy worms,
• soda,
• vinegar.

What we do

Take two large transparent glasses. Pour water into one and add soda. Mix. Open the package of gummy worms. It’s better to cut each of them lengthwise and make them thinner. Then the experience will be more spectacular.

Thin worms should be placed in a mixture of water and soda and mixed. Set aside for 5 minutes.

Pour vinegar into another glass. Now we add to this vessel the worms that were in the glass with soda. Because of the soda, bubbles will be visible on their surface. This means there is a reaction. The more worms you add to the glass, the more gas will be released. And after some time, the bubbles will lift the worms to the surface. Add more soda - the reaction will be more active and the worms themselves will begin to crawl out of the glass. Cool!

5. Make a hologram like in Star Wars

Of course, it is difficult to create a real hologram at home. But its likeness is quite real and not even very difficult. You will learn to use the properties of light and turn 2D pictures into three-dimensional images.

We will need:

• smartphone,
• CD box,
• stationery knife,
• scotch,
• paper,
• pencil.

What we do

You need to draw a trapezoid on paper. The drawing can be seen in the photo: the length of the lower side of the trapezoid is 6 cm, the upper side is 1 cm.

BoredPanda.com

Carefully cut out a trapezoid from paper and take out the CD box. We need the transparent part of it. Attach the pattern to the plastic and use a utility knife to cut a trapezoid out of the plastic. Repeat three more times - we will need four identical transparent elements.

Now they need to be glued together with tape so that it looks like a funnel or a truncated pyramid.

Take your smartphone and run one of the such videos. Place the plastic pyramid with the narrow part down in the center of the screen. Inside you will see a “hologram”.

Giphy.com

You can start a video with characters from Star Wars and, for example, recreate the famous recording of Princess Leia or admire his own miniature BB-8.

6. Get away with it

Every child can build a sand castle on the seashore. How about we line it up under water? Along the way, you can learn the concept of “hydrophobic.”

We will need:

• colored sand for aquariums (you can also take regular sand, but it needs to be washed and dried),
• hydrophobic shoe spray.

What we do

Carefully pour the sand onto a large plate or baking sheet. We apply a hydrophobic spray to it. We do this very carefully: spray, mix, repeat several times. The task is simple - make sure that every grain of sand is enveloped in a protective layer.

University of Exeter/Flickr.com

When the sand dries, collect it in a bottle or bag. Take a large container for water (for example, a wide-mouthed jar or an aquarium). Show your child how hydrophobic sand “works”. If you pour it in a thin stream into water, it will sink to the bottom but remain dry. This is easy to check: let the baby take some sand from the bottom of the container. As soon as the sand rises from the water, it will crumble in the palm of your hand.

7. Keep information secret better than James Bond

Writing secret messages with lemon juice is a thing of the past. There is another way to get invisible ink, which also allows you to learn a little more about the reaction of iodine and starch.

We will need:

• paper,
• brush.

What we do

First, cook the rice. The porridge can be eaten later, but we need a decoction - it contains a lot of starch. Dip your brush into it and write a secret message on the paper, such as “I know who ate all the cookies yesterday.” Wait for the paper to dry. Starchy letters will be invisible. To decipher the message, you need to moisten another brush or cotton swab in a solution of iodine and water and run it over what is written. Due to the chemical reaction, blue letters will begin to appear on the paper. Voila!

Children are always trying to learn something new every day and they always have a lot of questions. They can explain certain phenomena, or they can clearly show how this or that thing, this or that phenomenon works. In these experiments, children will not only learn something new, but also learn how to create various crafts, with which they can then play.

1. Experiments for children: lemon volcano

You will need:

– 2 lemons (for 1 volcano)

- baking soda

– food coloring or watercolor paints

- dishwashing liquid

– wooden stick or spoon (if desired)

- tray.

1. Cut off the bottom of the lemon so it can be placed on flat surface.

2. On the back side, cut out a piece of lemon as shown in the image.

* You can cut off half a lemon and make an open volcano.

3. Take the second lemon, cut it in half and squeeze the juice into a cup. This will be a backup lemon juice.

4. Place the first lemon (with the cut out part) on the tray and use a spoon to “remember” the lemon inside to squeeze out some of the juice. It is important that the juice is inside the lemon.

5. Add food coloring or watercolor inside the lemon, but do not stir.

6. Pour dish soap inside the lemon.

7. Add a full spoon of baking soda to the lemon. The reaction will begin. You can use a stick or spoon to stir everything inside the lemon - the volcano will begin to foam.

8. To make the reaction last longer, you can gradually add more soda, dyes, soap and reserve lemon juice.

2. Home experiments for children: electric eels made from chewing worms

You will need:

– 2 glasses

– small capacity

– 4-6 gummy worms

– 3 tablespoons baking soda

– 1/2 spoon of vinegar

– 1 cup of water

– scissors, kitchen or stationery knife.

1. Using scissors or a knife, cut lengthwise (precisely lengthwise - it won't be easy, but be patient) each worm into 4 (or more) pieces.

* The smaller the piece, the better.

*If the scissors do not cut properly, try washing them with soap and water.

2. Mix water and baking soda in a glass.

3. Add pieces of worms to the solution of water and soda and stir.

4. Leave the worms in the solution for 10-15 minutes.

5. Using a fork, transfer the worm pieces to a small plate.

6. Pour half a spoonful of vinegar into empty glass and start putting worms into it one by one.

* The experiment can be repeated if you wash the worms with plain water. After a few attempts, your worms will begin to dissolve, and then you will have to cut a new batch.

3. Experiments and experiments: a rainbow on paper or how light is reflected on a flat surface

You will need:

– bowl of water

– clear nail polish

- small pieces of black paper.

1. Add 1-2 drops of clear nail polish to a bowl of water. Watch how the varnish spreads through the water.

2. Quickly (after 10 seconds) dip a piece of black paper into the bowl. Take it out and let it dry on a paper towel.

3. After the paper has dried (this happens quickly) start turning the paper and look at the rainbow that appears on it.

* To better see a rainbow on paper, look at it under the sun's rays.

4. Experiments at home: rain cloud in a jar

As small drops of water accumulate in a cloud, they become heavier and heavier. Eventually they will reach such a weight that they can no longer remain in the air and will begin to fall to the ground - this is how rain appears.

This phenomenon can be shown to children using simple materials.

You will need:

- shaving foam

- food coloring.

1. Fill the jar with water.

2. Apply shaving foam on top - it will be a cloud.

3. Have your child start dripping food coloring onto the “cloud” until it starts to “rain” - drops of coloring begin to fall to the bottom of the jar.

During the experiment, explain this phenomenon to your child.

You will need:

– warm water

- sunflower oil

– 4 food colors

1. Fill the jar 3/4 full with warm water.

2. Take a bowl and stir 3-4 tablespoons of oil and a few drops of food coloring into it. IN in this example 1 drop of each of 4 dyes was used - red, yellow, blue and green.

3. Using a fork, stir the coloring and oil.

4. Carefully pour the mixture into a jar of warm water.

5. Watch what happens - the food coloring will begin to slowly fall through the oil into the water, after which each drop will begin to disperse and mix with the other drops.

* Food coloring dissolves in water, but not in oil, because... The density of oil is less than water (that’s why it “floats” on water). The dye droplet is heavier than the oil, so it will begin to sink until it reaches the water, where it will begin to disperse and look like a small fireworks display.

6. Interesting experiments: in a circle in which the colors merge

You will need:

– a wheel cut out of paper, painted in rainbow colors

– elastic band or thick thread

– cardboard

- glue stick

- scissors

– skewer or screwdriver (to make holes in the paper wheel).

1. Select and print the two templates you want to use.

2. Take a piece of cardboard and use a glue stick to glue one template to the cardboard.

3. Cut out the glued circle from cardboard.

4. TO back side Glue the second template onto the cardboard circle.

5. Use a skewer or screwdriver to make two holes in the circle.

6. Thread the thread through the holes and tie the ends into a knot.

Now you can spin your top and watch how the colors merge on the circles.

7. Experiments for children at home: jellyfish in a jar

You will need:

– small transparent plastic bag

– transparent plastic bottle

- food coloring

- scissors.

1. Place the plastic bag on a flat surface and smooth it out.

2. Cut off the bottom and handles of the bag.

3. Cut the bag lengthwise on the right and left so that you have two sheets of polyethylene. You will need one sheet.

4. Find the center of the plastic sheet and fold it like a ball to make a jellyfish head. Tie a thread in the area of ​​the “neck” of the jellyfish, but not too tightly - you need to leave a small hole through which to pour water into the jellyfish’s head.

5. There is a head, now let's move on to the tentacles. Make cuts in the sheet - from the bottom to the head. You need approximately 8-10 tentacles.

6. Cut each tentacle into 3-4 smaller pieces.

7. Pour some water into the jellyfish's head, leaving room for air so the jellyfish can "float" in the bottle.

8. Fill a bottle with water and put your jellyfish in it.

9. Add a couple drops of blue or green food coloring.

* Close the lid tightly to prevent water from spilling out.

* Let the children turn the bottle over and watch the jellyfish swim in it.

8. Chemical experiments: magic crystals in a glass

You will need:

– glass glass or bowl

– plastic bowl

– 1 cup Epsom salts (magnesium sulfate) – used in bath salts

– 1 cup hot water

- food coloring.

1. Place Epsom salts in a bowl and add hot water. You can add a couple of drops of food coloring to the bowl.

2. Stir the contents of the bowl for 1-2 minutes. Most of the salt granules should dissolve.

3. Pour the solution into a glass or glass and place it in the freezer for 10-15 minutes. Don't worry, the solution is not so hot that the glass will crack.

  How to arrange a kitchen

  Each of us has watched Hollywood films and certainly paid attention to the interiors there - spacious, functional and completely different...

Today there are a huge number of educational games for children. But conducting various experiments in a homely atmosphere will leave a lasting impression on the younger generation. With a minimal set of objects, it is possible to perform many experiments, which in the child’s mind will be perceived as a focus.

Experiments for children “Invisible ink”

To create this magical experience for children, you will need the following components:

• Lemon juice – 1 teaspoon;
• Drinking water – 0.5 tablespoon;
• Cup;
• Double-sided cotton swab;
• Blank sheet of paper.

The steps to send a secret message should be carried out in the following order:

1. Squeezed lemon juice and water are poured into a glass. Everything is thoroughly mixed.
2. One side of the cotton swab should be used as a writing instrument. It is dipped in a lemon solution of water and the required text is applied to a clean sheet of paper.
3. After completely dry secret information, the piece of paper with the message must be heated. For the experiment you will need a table lamp turned on.
4. Under influence lighting fixture, the encrypted letters will begin to appear, such an experience at home for your child will be an amazing knowledge of chemical laws.

Experiments for children “Commanding toothpicks”

When conducting this experiment, a child may well feel like a wizard. In order for this miracle to happen, you need to arm yourself with such items as:

• Toothpicks;
• Shallow cup of water;
• Rafinated sugar;
• Dishwashing liquid.

Using a minimal set and a few steps, you can conduct an experiment:

1. Place toothpicks on the water in the shape of sun rays.
2. Then slowly lower a piece of refined sugar into the water into the resulting center.
3. This action can pull the toothpicks towards the center of the bowl and the sugar cube.
4. And if you remove sugar from the container and apply a small drop to this place detergent, then the rays will begin to move away towards the edges of the cup.
5. The trick of these actions is that sugar, with its properties, sucks in air, thereby attracting nearby objects. On the contrary, soap solution is repulsive.

Experience for children “Floating Egg”

In order to make an egg float, you will need the following components:

• Raw chicken egg;
• Container with clean drinking water;
• Salt – 1 pack.

First, let's try to lower the egg into raw water. It just sank. Now take it back out and add salt to the water. That is, we create a strong saline solution. The next step is to try to make the egg float in salt water. And it really is on the water surface and does not sink. This happens due to the fact that salt creates an increased density of water, which is how this experiment for children turns out.

Experiments for children “Ice fishing”

The catch in this experiment for children will be a small ice cube. It will be caught from a glass of water, but your hands will remain dry. Scroll necessary materials described below:

• A glass of clean water;
• Frozen ice cube;
• A few granules of salt;
• A thread no more than one meter long.

When conducting this experiment, you must carefully monitor everything that happens so as not to miss important details. The order of performing the necessary operations is as follows:

1. A small piece of ice is dropped into a prepared glass of water.
2. The thread is placed with one end on the edge of the glass and the other on the ice cube.
3. Salt granules are sprinkled onto the ice where the thread is located. And the time is ticking. The waiting time is 5-10 minutes.
4. After the time has elapsed, by gently moving the edge of the thread, you can take out an ice cube. It will be attached to the thread.
5. This happens due to the salt, which melts the ice. And then pure water It just freezes the thread to the ice piece.

Experiments for children “Cold water boils”

To see the boiling bubbles in cold water, participants in the experiments will need the following components:

• A glass filled to the top with cold water;
• Pharmaceutical gum;
• Handkerchief.

All experimental techniques must be performed in a sink and in the appropriate order:

1. The handkerchief is generously moistened with water and wrung out.
2. Place a handkerchief on a glass of water and secure it with an elastic band. Moreover, the core of the scarf should touch the water surface.
3. Turn the prepared glass upside down and hold it in one hand. With the other hand, apply gentle blows to the bottom of the glass. From these actions, the water begins to “boil”, that is, to boil.
4. This occurs because the fabric of the scarf does not allow water to pass through from the glass. And upon impact, vacuum air is formed, which enters the water, your child will be delighted.

Experience “Creating a musical instrument”

When creating a musical flute for children at home from scrap materials, you will need the following items:

• Plastic straw;
• Scissors.

The future tool needs to be slightly flattened on one side and its side edges cut off. At equal distances from each other, three holes are cut on the surface of the straw. You just need to lightly blow air into it and close the holes one by one. The flute is ready to perform musical works, an excellent experience for developing hearing, imagination and logical modeling.

Experiment "Bird in a Cage"

To complete this experiment, you need to prepare the following materials:

• Scissors;
• White cardboard;
• Needle and thread;
• Compass;
• Colour pencils.

Following all stages of this experience will lead to an unforgettable experience of creating a cartoon. To construct it you need:

1. Using a compass, draw a regular circle on the cardboard and cut it out.
2. Poke a pair of holes with a needle on the sides of the circle and pull the threads through them. The length of the threads on both sides should be about half a meter.
3. On the outside of the cardboard you need to draw an empty cell. And on the other there is a small bird that could fit in this cage.
4. Then, taking the threads from both sides, you need to twist them with rotating movements.
5. When the twisted ends are stretched, they will unwind. And at this moment the child will be able to see the bird that is in the cage.

Experiments for children “Turning a square into a circle”

The focus of this test is the visual effect. To carry it out, the following materials are needed:

• Cardboard;
• Ruler;
• Felt pen;
• Pencil.

When performing the transformation trick, you need to cut a square out of cardboard correct form. Then, using a ruler, find the middle of one side. Attach one end to it measuring instrument, and bring its other end to the corner of the nearest side. Along the resulting line, using a felt-tip pen, you need to apply about 30 dots.

Find the middle of a cardboard square and pierce it with the sharp tip of a pencil. The cardstock should rotate on the pencil without much effort. When you rotate the square, you can see the resulting circle. Although these are just dots on the cardboard, they simply move in a circle and create a circle effect.

Experience "Mighty Power of Breathing"

Any child considers himself strong and brave. And in order for his confidence in this to be strengthened, it is necessary to conduct a similar experiment. To complete it you will need:

• Hangers for clothes;
• Thick thread;
• Book;
• Clothesline.

The implementation of all stages of the experience will lead to excellent results skill. The implementation of these activities consists of:

1. At a pre-selected place, you need to pull the clothesline.
2. Using threads, a book is tied to a hanger. It should not be in close contact with the hanger, that is, there must be free space between them.
3. The coat hanger hook needs to be hung on the clothesline. The design for the experiment is ready.
4. While at a short distance from the device, you need to blow on it with all your available strength. The result of these actions will be only a slight rocking of the book mechanism.
5. And if you change your breathing tactics from the same distance, the result will not be long in coming. With a slight increase in air exhalation, the design will begin to deviate. And then you can also slowly blow on the device. That is, the effect of power consists in the lightness and consistency of the blow.

Experiments for children “Record weight”

The materials needed to conduct the experiment for children are used:

• Small tin jars - 2 pieces;
• Paper;
• Glass jar, about 1 liter capacity.

The experiment consists of the following stages:

1. Cans made of tin material are placed opposite each other, at an approximate distance of about 30 centimeters.
2. A prepared sheet of paper is placed on top of them. It creates the appearance of a bridge.
3. You must place the jar on this laid paper bridge with careful movements. The result of such actions will be the fall of the glass container.
4. If you fold a sheet of paper into a typical accordion shape and place it between two tins, you will also get a bridge. But only with enhanced action. Because if you place a can on this structure, it will not fall, since the bridge does not even bend.

Whichever of these experiments is carried out among children, they will definitely remember its effect for many years to come.
