There are many interesting and safe experiments you can do at home. To do this, you can use what is in the house. Such experiments do not require a special place and special knowledge.
The essence of the experiment
A funny experiment can be done with an ordinary chicken egg, you can use a quail egg, and the process will go a little faster with it. The whole focus of the experiment is how to make a rubber egg from a regular egg.
For this, the egg is placed in vinegar and left for a certain time. Vinegar reacts with calcium, completely dissolves it. The shell leaves the protein in the form of gas bubbles. What remains in the end looks like a jelly elastic ball, in appearance and to the touch it seems that it is rubber. For those who are considering the option of making a rubber egg without vinegar, the answer is simple - no way! Without vinegar, the desired reaction will not occur, and the experiment will fail or the result will be wrong.
The first stage of the experiment
Now you will learn how to make a rubber egg at home. To do this, prepare 9% vinegar, one egg and glassware.
An egg is placed in a transparent bowl and poured with vinegar so that it completely disappears. The reaction begins instantly, immediately carbon dioxide bubbles appear on the shell. In bird eggs, the composition of the shell is 90% calcium carbonate.
When exposure to acid occurs, the shell begins to soften and disintegrate into small elements. During decay, a chemical product is emitted - carbon dioxide. To understand how to make a rubber egg, you do not need to have special knowledge in chemistry. The only thing you need to know in this case is that you can’t eat such an egg. Now everything needs to be left for 15-24 hours.
Continuation of the experiment in a day
After the specified time, the egg must be removed from vinegar. You can do this without gloves, with short-term contact with the skin, nothing bad will happen. It will be noticeable to the naked eye that the egg has increased in size, the remains of the shell are left on it, but now they are more like white powder. These residues must be washed off in water. Here is how make a rubber egg with your own hands. It was saturated with vinegar and felt like thick jelly or rubber. The color of the protein became darker, and the yolk remained in the same condition as before.
The egg can be squeezed a little, it bounces well from a hard surface, like a hopper. But throwing it from a great height or applying force when throwing is not worth it. Only the upper shell becomes dense, and part of the protein and yolk remain in a liquid state. When you try to cut this "hopper", the contents flow out. If you enlighten it, you can see where the yolk is.
White egg
In addition to this method, there are other options for making a rubber egg. In this case, it will not be transparent, but white. The whole experiment is carried out in the same way, only acetic acid is used instead of vinegar. After keeping the egg in the chemical for the prescribed time, it also needs to be washed under running water, in this case, the hands should be protected from acid and use gloves.
The outer shell also completely dissolves, but the egg itself is white in color, like a boiled egg, and it’s not so elastic to the touch, it does not spring if it is thrown onto a hard surface, but the experiment is also interesting.
Colored eggs
It is very fun to conduct such experiments, it is also interesting to amuse oneself with the resulting jumpers, they fulfill a peculiar role of antistress. That is why it is possible to make such “jumpers” multicolored.
How to make a rubber egg colored? It’s very simple to add egg dye to vinegar. Such dyes have a persistent and saturated color, they dissolve well in vinegar. In the package with dyes there are different colors. For such an experiment, you need to prepare as many dishes as how many colors will be used in the experiment. How many flowers, so many eggs. One egg is placed in each dish and powder of the desired color is added. Pour vinegar over it and wait for the set time. When the residual plaque from the shell is washed off, only the colored “hopper” will remain.
Of course, do not forget that the egg did not actually turn into a rubber ball, and you do not need to put it in the toys. Over time, it still deteriorates, or from mechanical damage begins to leak and dirty things. It’s not pleasant to dirty your own spoiled egg, its smell is terrible and it is washed off gradually. If in the first couple of days it does not tear, then it is better to throw it away. If you wish, you can always make a new "rubber ball".
