With the volcano science experiment, you will see that chemical reactions can be seen in a simple and fun way! Indeed, what we are and what we consume are the result of a large number of chemical reactions, which you do not even suspect because they are invisible.
Make a volcano with the sand on the baking plate.
Position your glass to form the crater and finalize your volcano by putting enough sand to cover the edges.
In this glass, add two teaspoons of baking soda and 2 tablespoons of water.
Then add the red food coloring and a little washing-up liquid.
With a spoon, gently mix the mixture.
Now is the time to have fun! Pour vinegar in the crater and observe!
Cool right?
In contact with the vinegar, you observe a significant foam that leaves the volcano immediately, like lava after a volcanic eruption. This foam is the result of a chemical reaction between vinegar and baking soda. We’re talking about effervescence. It means that a big quantity of gas escapes from a liquid.
Why does it react?
Vinegar is what we call “an acid”. While baking soda is “a base”. When these two compounds react, they form, among other things, water and carbon dioxide. The bubbles you observe are carbon dioxide which escapes from the reaction. The famous greenhouse gas.
This gas is not dangerous and it composes our atmosphere.
The reaction between the vinegar and the baking soda is instant, as you can see. The addition of dishwashing liquid makes it possible to obtain a thick foam to form beautiful lava that drips slowly on the sides of your volcano. Like a real one!
The chemical reaction between vinegar and baking soda can be used to degrease greasy surfaces. It is a more ecological solution than the products found in the supermarket.
A breathtaking illusion in which you will change the shell of an egg into silver. Long live physics. […]
Observing a chemical reaction in your kitchen is possible with the volcano science experiment. Build your volcano with sand. And then let’s move on to making lava. […]
Here is a great and visual experience for you to discover the secret world of bacteria. They are very useful to us and we use them in many cooking recipes, for example. Watch how bacteria turn sugar into alcohol and carbon dioxide using a simple soda bottle and a balloon.
It’s a great way to identify which drinks have sugar and which doesn’t. […]
