There are always a lot of things to do in the kitchen and it is sometimes simply impossible to keep track of everything. What if you put all the eggs in the refrigerator, and then remember that one of them is boiled? How to distinguish it from the rest?
It is necessary
- - unidentified egg;
- - flat plate;
- - thick elastic bands, strings;
- - raw egg for comparison, kitchen scale.
Instructions
Step 1
Break the egg. This is the easiest way, but you need to have the recipe and other ingredients ready to prepare the dish, because a broken egg does not last long. A raw egg can be added to scrambled eggs or scrambled eggs, kneaded for pancakes, and boiled eggs can be used in salads or sandwiches.
Step 2
Launch into orbit. Take a flat plate or simply place an unknown egg on a flat surface and make it spin. The content of a raw egg is a liquid substance that responds late to rotation and thereby inhibits the movement of the hard shell. Such an egg will turn a maximum of twice and stop. A boiled egg will spin for a long time and almost evenly, since it is a single whole: during cooking, the white and yolk thicken and become a dense mass. If the rotation of a boiled egg is stopped, it will remain motionless, while a raw egg will spin by inertia for some time. This method is the most common and reliable.
Step 3
Another option for physicists: wrap a raw and unknown egg with thick rubber bands along the longitudinal side. Hang up on strings. Turn the same number of turns and release. In this case, the boiled egg will rotate for a long time, then one way or the other, gradually decreasing the number of revolutions. The raw one, after returning the rope to its previous state, will make one or two turns and stop.
Step 4
Compare with its raw counterpart. Take an unknown egg and a known raw egg of the same size and grade for comparison. Weigh the eggs one by one on a kitchen scale, record the weight. A boiled egg will be heavier because the density of the protein and yolk increases after boiling. This method has a low degree of reliability, since the difference in weight is determined by units, a maximum of ten grams.
Step 5
Ask the chicken. Take the unknown egg to the hen house and watch the reaction of its inhabitants. If the hens bury the egg, then it is definitely boiled. If they start to incubate, then it is raw. This method is good for those who have a sense of humor, as well as extra time and access to the chicken coop.
