1. Making a volcanic cone
To make a cone model you will need:
1. Plastic bottle.
2. Plasticine.
3. Scissors.
4. Any building mixture - gypsum, putty, dry tile adhesive, ready-made plaster mixtures.
First of all, cut off the top third of the plastic bottle.
We discard the lower part - we will no longer need it. With the top third remaining, use nail scissors to carefully cut off the neck with a small plastic gap - it will play the role of the crater of our future volcano.
We coat the cut plastic cone with plasticine, modeling the shape of the future volcano.
We apply any construction mixture mixed with water onto it.
The photo shows a mixture of tile adhesive and acrylic putty, but gypsum, cement or ready-made dry plaster will do.
Into the cone, tightly and picturesquely coated with putty, insert the inverted top of the bottle with the cap tightly closed.
In order for the mass to harden, dry and strengthen, we leave the potential volcano for several hours in a dry place.
2. Demonstration of a volcanic eruption
To simulate a volcanic eruption, we will need baking soda, 100 ml of vinegar and red watercolor paint.
Using a brush, wash watercolor paint into a glass with vinegar.
The more dye there is, the more spectacular the eruption will be.
It is better to place the cone in a dish or bowl so as not to stain the table with our “lava”, and pour 2 teaspoons of soda into the conditional crater.
After this, slowly pour the colored vinegar into the soda crater.
If you have not mixed up or spared the components, you will witness a unique spectacle - the eruption of a homemade man-made volcano.
Such an elementary chemical-geographical experiment can be demonstrated to your own children, who are going through a period of fascination with the history and nature of the Earth. This number looks no less impressive in school lessons - in the 6th grade, in the process of studying the topic “Lithosphere”.
