How to make a volcano at home. Do-it-yourself volcano spewing lava: a step-by-step master class How to make a small but better model of a volcano

Surely everyone has seen on TV or on video on the Internet such a bewitching and rare sight as a volcanic eruption. Naturally, it is very difficult and rather dangerous to observe this manifestation of the fiery element with one's own eyes. But you can easily design your own volcano at home. Let him not exact copy real, but with the help of this model it is easy to demonstrate the principle of the volcano, which, no doubt, will appeal to little explorers. Using a photo selection, we will show how to make a quick and easy erupting volcano from homemade or purchased plasticine, also with our own hands!

Perhaps the child will even want to join the manufacturing process. Everyone knows that co-creation is very useful for strengthening family relations. Such a model would be useful as visual aid, in geography lessons, taking pride of place among the usual, static layouts.

At first, this task may seem incredibly difficult, because for this you will need to purchase some special reagents. Yes, you can find a ready-made kit for creating a volcano in art stores. But you can try to build a model at home without special preparations.

To make a model of a volcano, you first need to understand how a real volcano works. Pictures representing a volcano in a section clearly show its structure. It is clear that inside the mountain there must be a cavity filled with lava. From what it is better to make them, you will learn further.

How to make a do-it-yourself volcano from plasticine and mortar

What will be required:

  • big plastic bottle;
  • plasticine;
  • building mixture;
  • watercolor and brush;
  • scissors;
  • soda;
  • table vinegar.
  1. Cut off one third of the bottle, the one with the neck. The lower part is not needed - set it aside. Carefully cut off the neck from the top, leaving a small gap.
  2. Knead the plasticine well so that it becomes soft and sticky. Glue them over what is left of the bottle. Give the workpiece the shape of a volcano.
  3. Dilute building mix water until it acquires a thick, like sour cream, consistency. Apply it to the plasticine base.
  4. Place the neck of the bottle into the mouth of the future volcano, cap down. Before doing this, make sure that the lid is tightly screwed on. Mask the plastic on top with the remaining mixture.
  5. Place the structure in a warm, dry place and let dry.
  6. While the volcano is drying, prepare the components for the demonstration of the volcanic eruption. Color the vinegar red with watercolors and a brush.

Put the dried layout in a wide bowl. Place 2 tablespoons of baking soda in the volcano crater and then slowly pour the vinegar over it.

The photo shows how a homemade volcano erupts:

Instead of plasticine, you can use old newspapers as papier-mâché.

Making a model of a papier-mâché volcano in a simple master class

Necessary materials:

  • plastic bottle;
  • a piece of thick cardboard;
  • newspapers cut into strips;
  • water;
  • flour;
  • acrylic paints;
  • paper tape;
  • brush.
  1. First, make the base of the model out of cardboard and a bottle. Glue the bottom of the bottle to the cardboard, then, starting from the neck and ending with the base, stick the strips of tape so that they form a cone. Glue newspaper strips to the resulting cone.
  2. Take 1 part flour and 2 parts water, cook a paste. Saturate scraps of newspaper with this composition and glue over the base of the volcano. Give the layout the shape of a volcanic mountain.
  3. Leave the finished craft to dry completely.
  4. After some time, you can start painting. Children can also cope with this stage of production.
  5. Let the paint layer dry. Everything is ready for the experiment with the eruption. Fill up the bottle warm water with addition liquid soap or dishwashing liquid.

Thanks to soap solution the release of foam will be plentiful. Add a couple of spoons of soda to the mixture, and then pour in the vinegar and get ready for observation.

There are other "lava" recipes for a homemade volcano. A volcano erupting green ash looks very impressive. The following instructions will help you make such a volcano in stages.

For the experiment you will need ammonium dichromate. You can find it in any standard set " Young chemist". Take care of fire safety– conduct the experiment on a non-combustible surface.

Pour sodium dichromate powder into tin can 7 cm high. Place a piece of cotton wool soaked in alcohol in the center of the resulting slide.

Roll a sheet of paper into a cone 15 cm high and 20 cm in diameter. Cut off 5 cm from the top. Cover the tin container with a cone so that it is slightly below the reagent slide. Trim the paper more if necessary.

Now set fire to the cotton wool and admire the flakes flying to the sides.

A homemade volcano will come in handy if you want to participate in an exhibition of themed crafts, or just spend time doing an interesting experiment. And if you have any difficulties with the implementation of the experiment, pay attention to the attached videos.

Hello, friends! Today I want to tell you about how to make a home volcano with your own hands in just a couple of minutes.

This action is very exciting and truly bewitching, both for children and adults, so I highly recommend trying it 🙂

What you need to make a volcano at home

In fact, making a volcano is very simple. We collected it even without vinegar, because the smell of vinegar is not very pleasant for children.

So, for the simplest and most smellless 🙂 volcano, we need:

  • bottle;
  • plasticine for decorating the bottle and making the "mountain";
  • soda;
  • citric acid (in a ratio of 1 to 2);
  • a container for mixing ingredients and a spoon;
  • water and a little dishwashing detergent (so that there is more foam);
  • food coloring (optional)
  • a plastic container for creating a themed sensory box "Volcano";
  • small figurines for the sensory box (if you make a volcano in a box);

How to make a volcano

Our goal was not only make a volcano, but also to embed it into the general thematic canvas, so we made a sensory box. It turned out just super and was able to keep Gleb busy for three hours for sure 🙂

We played a treasure island (the pirate theme has been prevailing here for a very long time :-)) and on our island, where the pirates sailed in search of treasure, a volcano erupted.

making a volcano

For volcano we took a bottle and to give it the appearance of a mountain, they covered it with multi-colored plasticine.

Of course, it was possible to make the mountain even more gentle, but there was no longer the strength to endure, I really wanted to see the volcano in action 🙂

Our island was rocky, so we put stones in a container, placed a volcano in the center, and around it were pirates and a treasure chest.

Magic powder

Now it's time time to make "magic powder", which at the right time will ignite the volcano. There is really nothing magical here, just a mixture of baking soda and citric acid(in a ratio of 1 to 2), but the result of the reaction for the child will be truly magical, believe me 🙂

Conveniently immediately pour a lot of powder into a container and prepare a spoon (small), otherwise the child will go into a rage and it will be difficult to be distracted by making an additional portion of the magic powder.

Can be in powder add food coloring so that the foam is colored. We added red to make the lava red. It turned out really well 🙂

Eruption

And then everything is simple: you just need to pour the magic powder into the mouth of the volcano and it will turn out - magic!

For clarity - filmed for you small video. I hope you enjoy our volcano 🙂

With love,

During a volcanic eruption, ash clouds are thrown into the air, and lava flows along the slopes. This is a very exciting sight, it is life-threatening to watch it in close proximity.

But you can make a volcano at home and conduct experiments daily, admiring the eruption without a threat to life and health. By demonstrating active volcano friends, you will surprise them. You can prepare a presentation for a school lesson, and thereby add variety to boring lessons, and teachers in geography and chemistry will surely mark your efforts with good grades.

First make the volcano itself.

How to make a paper volcano

To make a volcano, it is best to use thick paper or cardboard.

Draw a large circle on paper. Cut it out and glue the cone.

From the second sheet of paper, twist the tube and glue it. This will be the mouth of the volcano. Put a cone on it and fasten the structure with glue.

Cut out the ground from the third piece of paper. It can be given any shape, the main thing is that it should be in size more ground volcano. Glue the volcano to the ground, cover it with tape. Apply superglue on top and sprinkle with sawdust, sand. You can use colored sand. Paint the model with gouache or acrylic paints and give the volcano a natural look.

To prevent paint from flowing during or after the eruption, cover the volcano with a protective layer. The composition can be prepared independently: mix 1 part glue and 3 parts water. After thorough drying, the volcano model is ready for use. Lava in a test tube is inserted into the mouth of a volcano.

Volcano how to make from plasticine

Plasticine is divided into 2 parts.

The first part is rolled into a pancake (base or land). From the second part, fashion a hollow cone, with a hole in the middle.

Place a bottle with a cut neck on the base. Put a cone on top, stick around the bottle opening with plasticine. Fasten the base and cone of the volcano together to form an airtight structure.

Color the model and sculpt the slopes. The prepared substance for lava is poured into the bottle through a watering can.

How to make a plasticine volcano model the second way

Instead of plasticine, you can use salty dough, mass for modeling, papier-mâché.

Glue the bottle to the base (upside down plastic bowl, thick cardboard, chipboard) with tape so that you get a cone-shaped tent.

Cover with plasticine on top. Form lava flows, mountain range elements, channels. If you used salt dough, dry the volcano.

Now you can paint the model. For a more spectacular eruption, red paint can be applied to the mouth of the volcano. Once the paint is dry, apply a clear sealer.

Attach to the base plastic plants(usually they decorate aquariums) - you get trees and shrubs. Dry the volcano well again before use.

How to make a cold porcelain volcano model

If you wanted to use modeling mass to make a volcano, but did not find it in stores, or the price turned out to be high, you can prepare cold porcelain. This is soft material, homogeneous in structure. It is convenient to sculpt from it small parts, because it is very plastic, and hardens when solidified.

Mix one part starch (corn or potato), soda, water. Add a drop of vegetable oil.

Put the mixture on the fire and cook until it thickens, stirring constantly. Remove the thick mass from the pan and cover with a damp towel. When the mass becomes warm, knead it. It should be soft, and resemble plasticine. The mass can be dyed desired color during cooking. Best for this Oil paint. But keep in mind that then "cold porcelain" will quickly harden. So that the mass does not stick to your hands, grease them with oil or a fat cream. Sculpt the volcano as described above and let it dry. Then paint with acrylic paints.

Eruption preparation.

How to make a soda volcano

The easiest way to make lava is from baking soda and vinegar. The quantity is given for a volcano with a "volume" of 100-150 ml.

1 st. mix a spoonful of soda with 1 teaspoon of dishwashing detergent (preferably red), and red dye (beetroot juice can be used). Stir the mixture well, if the lava is very thick, add water. Pour it into the crater of the volcano.

To start the eruption, you need to add 2.5 tbsp. spoons of vinegar. The vinegar will react with the baking soda and the secretion will begin. carbon dioxide. As a result, a bubbling red foam will form.

How to make a homemade green ash volcano

For this experiment, you will need ammonium dichromate (NH4) 2Cr2O7. It is included in any standard Junior Chemist set. The experiment must be carried out on a non-combustible surface.

Pour ammonium dichromate into an unnecessary jar of tin 7 cm high. In the center of the slide, make a recess and put a cotton swab moistened with alcohol.

From brown paper, roll a cone 15 cm high, 20 cm in diameter. Cut off the top of the cone by 5 cm. Cover the reagent jar with the cone. Make sure that the cone is slightly lower than the slide, if necessary, cut the paper further. Set fire to the cotton wool and admire the flying green flakes.

How to make a do-it-yourself volcano that erupts with a sheaf of sparks

The eruption turns out to be spectacular, but it must be carried out, observing the rules for working with combustible substances, and conducting the experiment on the street under the supervision of adults. If careless, you can start a fire or get fourth-degree burns.

Mix 4 parts of potassium nitrate with 2 parts of aluminum (source of sparks) sawdust and 1 part of sulfur. To get enough sawdust, drill a few holes in the metal.

On the bottom of the cardboard sleeve (you can buy it or take it after the used factory pyrotechnics, you can make it yourself) install a clay plug. The wall thickness of the sleeve is 4 mm. Pour and tamp the mixture into a sleeve. Cover with a cardboard circle on top (its diameter is equal to the inner diameter of the sleeve), and then fill it with plaster.

In the middle of the plaster plug, drill a hole for the pyrotechnic mixture and pass the wick. This will be the crater of the volcano, before the eruption, light the fuse and move to a safe distance.

A volcanic eruption is an unusual and mesmerizing sight. Today we have the opportunity to see this riot of nature in archival footage, which can be easily found on the World Wide Web. To be present at this spectacle live is problematic, and unsafe. But there is a wonderful alternative to video filming and risky activities - to make a do-it-yourself volcano model. Of course, in this case it will be very far from plausibility, but, nevertheless, a clear demonstration of the principle of the volcano's operation will not leave little researchers indifferent.

In addition, it will be useful to involve the child in the manufacturing process itself, because joint creativity brings together and contributes to the establishment of trusting relationships in the family. And if your student presents a hand-made model of a volcano at school, for example, at a thematic geography lesson, this will not go unnoticed among classmates and teachers.

So, we found out everything about the expediency, it remains only to understand how to make a do-it-yourself volcano model? At first glance, the task is very difficult, since it seems that it is necessary to purchase some special materials and reagents. Indeed, in stores you can buy a ready-made kit for creativity with plaster, paints and detailed instructions how to make a volcano at home. But you can try to create a model without special preparations, practically from improvised materials.

We bring to your attention a few ideas about what and how to make a volcano.

How to make a volcano from plasticine and mortar?

We will need:

  • plastic eggplant from under the water;
  • building mixture, for example, plaster;
  • plasticine;
  • watercolor paints;
  • scissors;
  • baking soda;
  • table vinegar.

Working process:

  1. Cut off the top of the bottle - about a third.
  2. We no longer need the lower part of the bottle, but from the top we need to carefully cut off the neck, leaving a small gap.
  3. We cover the cut part with plasticine, giving it the desired shape of the future volcano.
  4. On the plasticine base we apply the building mixture, previously diluted in water.
  5. We insert the inverted neck of the bottle into the “vent of the volcano”, smeared with the mixture, after carefully wrapping the lid on it.
  6. We leave the structure in a warm, dry place until the mixture has completely dried.
  7. In the meantime, we are preparing to demonstrate the volcanic eruption with watercolors, vinegar and baking soda.
  8. Paint the vinegar red with a brush.
  9. We put the dried volcano in a bowl or plate, and put 2 tablespoons of soda in the "crater".
  10. Slowly pour the colored vinegar into the baking soda.
  11. We observe the eruption of a volcano made by hand from plasticine and building mixture.

Not everyone has the opportunity to show a child a real volcano - they are far away, and walking on them is dangerous. But in order to get acquainted with the principle of the action of volcanoes, to study the processes that take place inside, a small volcano, made as simple as possible with your own hands and launched, is quite suitable. Showing a miracle to a child is very easy, and this craft can also be used at school for projects.

Learning to make a big do-it-yourself volcano from salt dough

There are many ways to make a volcano. In one option, you will need salt dough. Also needed for work: flour (about 400 gr.), Salt (200 gr.), Water (150 ml), paints (watercolor, gouache, acrylic or food coloring, glass cup or plastic bottle, vinegar, baking soda, plywood or a piece of very thick cardboard.

First, the dough is kneaded. It should be steep, very salty, thick, but plastic. Ideally, it should not stick to your hands, but it is easy to acquire the necessary shape and be pliable. The base of the volcano is formed from salt dough.

A glass or a bottle is placed in the center, the mass is distributed around and a mold of the mountain is formed. For greater similarity with the real one, strands of mountain ranges are molded in the layout, holes are made for lakes or furrows for rivers. You can make several holes in the dough with a toothpick. After the workpiece has solidified, branches are inserted into them or ornamental plants from the aquarium.

In the air, the finished cast completely hardens within a few days. You can speed up the process in the oven; at a low temperature, the workpiece is baked for about 20 minutes.

The next step is coloring. Paints draw greenery at the foot of the mountain, gold deposits, blue rivers. The top of the mountain is painted in red and white - the color of snow or lava.

In order for the volcano to begin to “breathe with lava”, water with detergent is poured into a glass or bottle that stands in the center. Pour a couple of tablespoons of vinegar inside. Just before the performance, vinegar is poured into the glass. A mixture of soda and vinegar reacts and after a few seconds, the lava will rise and begin to run along the slopes of the volcano. If you add food coloring to the detergent, then the lava will be like a real one - red.

Plasticine volcano.

Such a volcano is easy to make from plasticine. The skeleton of the mountain is made of plywood or cardboard cone. The dimensions of the cone are chosen based on the size of the volcano.

The cone is plastered with plasticine - brown and black in the color of the earth, white and red - the top is covered in snow with lava, the foot is green and blue. You can also make several three-dimensional figurines of trees or animals and place them on the slopes of the mountain.

A glass or bottle is placed inside the cone, a mixture of detergent, vinegar and soda is poured into the middle.

It is important to remember that such a filler foams very strongly, so it is imperative to lay something under the base. A tray with low sides, which is decorated to match the volcano, is well suited.
Papier mache volcano.

You can make a volcano out of papier mache. Required to work a large number of newspapers and papers.

A cone is formed from whole newspapers. Newspapers are crumpled and taped to each other.
Then pieces of paper are glued on top of the crumpled newspapers with glue. There must be 5 - 7 layers for the volcano to be strong. Inside, as in other options, a container is placed, which will be filled with lava. You can cut out animals, plants, birds from paper and place them on the slopes of the future volcano. It is necessary to paint a papier-mâché volcano with paints, acrylic and gouache are well suited - they sigh for a long time, but are durable and will not flow during an eruption.

Volcano from polyurethane foam.

If you ask your dad for help, you can get a great foam volcano. Foam is good because with a gun you can create various forms, which will be very similar to a real mountain. The foam dries for a couple of days and only in natural conditions, it is not worth speeding up the process - the volcano can lose its shape.

A lava container is placed in the middle of the volcano. It can be a jar, a bottle or a glass. If the workpiece is immediately filled with foam, along with the container, then it will be impossible to pull it out later. If you first make a model of the volcano, and then make a hole with a clerical knife, then the container can be removed. The foam is easy to cut, it is convenient to use a clerical knife for work - they can cut small holes and neat edges.

Paint comfortably with a wide brush. You need to paint over well so that the pores of the foam are not visible under the paint. Such a volcano will be light and beautiful. The slopes of the mountain are easy to decorate with plants. Figurines of animals and birds.

More ideas on how to make volcanoes can be seen in a selection of videos.
