Why put half the egg with toothpaste? Experiment for children with eggs

On TV screens you can see not quite understandable for the average consumer advertising, in which dentists make an unusual experiment with a simple chicken egg. What is the essence of such a demonstration - why put half of the egg with toothpaste? Let's try to answer this question from the point of view of scientific knowledge.

An advertising trick or a reality?

Today, many manufacturers of toothpastes have adopted the so-called trick with the egg, using it in commercials. But the ideological inspirer of such a marketing move is the company "Blend-a-honey". It was she who first showed consumers such an experiment. In the video, the dentist offers to spread one side of the egg with toothpaste, and leave the other as it is. Then it should be lowered into a liquid medium, similar to the one in the oral cavity. After delivering the egg from the liquid a day later, the doctor demonstrates to the spectators the following result: the half that was smeared with toothpaste remained white and firm, and the other became soft.

With advertising everything is clear, but how much is it believable? Let's try to figure out why half of the egg is smeared with toothpaste.

What is the point?

What is the meaning of such advertising, what did the manufacturer want to demonstrate in this way? Why put half the egg with toothpaste and leave the other unchanged? With the help of this marketing approach, the seller focuses on how their dentifrice protects enamel. From the side where the toothpaste was, the shell remained solid and white, and with the "unprotected" completely dissolved, changed color. The manufacturer demonstrates to the audience how their product will take care of teeth and what can be, if you do not use this toothpaste.

Here is such an unpretentious idea became a real legend in the advertising field. Thanks to this move, the demand for the advertised product has grown significantly. And similar advertising spots began to produce and other companies producing toothpastes.

What happens to the egg in the vinegar?

Let's see what really happens. We hasten to upset gullible spectators - not everything in this video is true. Firstly, in an acidic environment, the shell can not remain white, even if it smears half of the egg with toothpaste; And secondly, we do not have pure vinegar in our mouth, so the concern that teeth in the near future will become soft, if not to use the advertised product, is a pure water marketing trick.

Then why half the egg smear with toothpaste, what will happen in reality? The truth in the commercial is still there - the toothpaste, which contains fluoride and calcium, will really protect the shell from destruction. But very little! The effect that is demonstrated in advertising, namely a snow-white hard shell, is impossible to achieve in reality. The egg will noticeably soften and change color, regardless of whether it is smeared with toothpaste or not.

Nevertheless, the difference between the two halves will be noticeable. Therefore, you can offer to perform such a simple experiment with children. In this way, the toddlers will get acquainted with the effect of the toothpaste, the necessity of its application. How to conduct such a job is described in detail below.

Experiment for children

Thanks to this practical study, children will understand how important it is to clean teeth. For the experiment, you need these materials:

• Raw chicken egg (1 or 2 pieces);
• Any toothpaste;
• Brush;
• A glass jar with a lid;
• Vinegar is 9 percent.

Take with the baby a chicken egg. For the purity of the experiment, we suggest using 2 pieces - then the result becomes clearer for the child. We offer the child to spread one egg (or half) with toothpaste using a brush. The other (or the second half) is left unchanged. Both eggs are carefully lowered into a glass jar, after pouring vinegar there, cover it with a lid. The kid will certainly ask the adult about why to smear half of the egg with toothpaste. The answer to this question he will receive at the end of the experiment.

Now you need to wait 12 hours. After this, you need to remove the eggs from the acid medium. What will happen? And here's what:

• Untreated toothpaste shell completely dissolved. The egg will change color, become soft and "jumping";
• On the other, the shell will become much thinner, but it will not dissolve completely.

Thus, after analyzing the results, you can answer the child's initial question about why half of the egg is smeared with toothpaste.

In this article, we shared the idea of an interesting cognitive experiment with children. In addition, they explained why it is necessary to smear a half of the egg with toothpaste, for which it is necessary and what result to expect.
