A volcano is a geological formation on the surface of the earth's crust (for example, a mountain or hill), under which there is a hole (crack, a fracture in the earth's crust). Through it outside face glowing magma, forming lava, and volcanic gases.

The volcano

You can easily make your own model volcano, having simple materials.

You will need:

Clay, vinegar, soda, tray, bottle, funnel, food coloring.


The experience is best done under adult supervision!

On the tray vilepi clay volcano with crater (mountain with a hole in the center). In the crater place a plastic bottle.
Using a funnel mound in a bottle of baking soda to half.
Mix the vinegar with red food coloring and pour through a funnel into the bottle.

...And your volcano starts to erupt!

In the interaction of acetic acid with sodium bicarbonate (baking soda) is a rapid chemical reaction which produces a large quantity of carbon dioxide. He rushes outside the bottle with a thick mass, which was formed in the bottle, causing it to bubble.

If in the bottle to pour only a pinch of soda, the reaction will go, but not as rapidly, and you will get only the hiss of the gas in the bottle, not a powerful eruption.

You can just pour in a container of soap,then add citric acid and red dye in a separate container to pour the water and dissolve it in baking soda,then pour the soda in this Vulcan(in which soap,acid and dye)And the start of the reaction a little better than this.
