If you don t break the egg, how to protect the egg so that it won t break

I did. Wrapping it in plastic foam works best. Or you can do a parachute, the parachute is related to the shape and is difficult to do.

Eggs hit the earth.

Demonstration of scheme solicitation.

Eggs hit the earth.

Soft filling material can be added, eggs can be packaged in ordinary containers, and parachutes can be used as a deceleration device.

Zhai Liyuan, senior engineer of the China Institute of Science Popularization).

First, the question is raised.

Leonardo da Vinci was a well-known artist and inventor who spent months at his desk practicing painting eggs day and night, and eventually he was able to bring them to life.

Not only Da Vinci and eggs have a fate, since the 80s of the 20th century, many teenagers in European countries, Hong Kong, Shanghai and Guangzhou have also formed an indissoluble bond with eggs - using eggs to hit the earth.

2. Applicable objects of the activity.

This activity is applicable to three groups of teenagers: 9-12 years old, 12-15 years old and 15-18 years old.

3. Purpose of the activity.

Learn to apply creative thinking to choose the best solution to a problem; Try to create with a combination of hands and brains.

4. Preparation for the event.

Raw eggs, parachute materials, cushioning packaging materials, etc.

5. Activity content.

As we all know in daily life, raw eggs will break when they fall from the table to the ground. Isn't this "eggs hitting the earth"? Otherwise, when the egg hits the earth as we are talking about, not only the distance between the egg and the ground is much greater than the height of the table, but also two other conditions must be met.

1. The height at which the eggs fall.

In the egg hitting the earth activity, the egg is required to fall from a height of more than 15-20 meters and collide with the ground, that is, the students participating in the activity are required to make the eggs fall from the balcony or window of the 4-6 story building.

2. Make the eggs hit the ground without breaking.

It can be considered in two aspects: one is to extend the interaction time between the egg and the ground impact, which can be achieved by packaging the egg in an ordinary container (the material, shape and structure of the container is not limited); The second is to reduce the speed of the egg at the moment before it hits the ground, which can be achieved by adding a parachute that acts as a deceleration on the packaging container.

However, it is also important to consider that the eggs must fall into the demarcated circle, which adds to the difficulty. Students should constantly think, design, experiment, and make choices, and most importantly, use everyone's intuition.

We believe that through the above activities, students will be able to invent and create; Many ingenious devices that can ensure that the egg hits the ground without breaking will be born on everyone's nimble fingers.

6. Background materials.

In the early 80s of this century, the activity of eggs hitting the earth was seen in the youth science and technology activities organized by the Youth Department of the British Association for the Promotion of Science and Technology, and was later introduced to Hong Kong by the teachers of the Hong Kong Association for Mathematics and Physical Education and carried out among primary and secondary school students. In the early 90s, the Children's Palace of the Shanghai China Welfare Association further improved it and organized it among the young people in Shanghai, which was welcomed by the young people. Subsequently, the teachers of the Guangzhou Physics Teaching and Research Association organized a "Egg Hitting the Earth" competition in Guangzhou, which attracted many young enthusiasts to participate.

You can pull a hydrogen balloon from it.

That is, after hanging up, the rising strength of the hydrogen balloon is controlled just enough to let the egg fall slowly after hanging the egg.

Make a large parachute, wrap the eggs well, tie them under the parachute and drop them.

Put the eggs in the bucket and throw the bucket down together, hehe, I thought about it, I haven't tried it

Just put a thick sponge downstairs and put it on the mat!!

Soak the eggs in vinegar for a few days and they will become soft!

Hehe, I remember that there is an episode of Chess Ideas that has done a program in this regard, and I suggest you look for it again!!

You soak the egg in vinegar for two days, and it won't rot if it falls to the ground.

1. Regret Hong wide egg tray: paper egg trays can be used to protect eggs, paper egg trays are suitable for large quantities of egg transportation protection, which is very practical. 2. Plastic egg cartons:

Plastic egg cartons can fix the eggs well, so that the eggs can avoid excessive collisions, and have a good effect on protecting the eggs. 3. Sponge cushion: Sponge cushion can effectively reduce the degree of collision of eggs, so as to protect eggs.

How do you preserve eggs?

First of all, if you want to keep eggs at room temperature, you must know why eggs spoil, eggs without cracks are generally placed at room temperature and will not spoil for a week. However, eggs with cracks will basically go bad in 2 days, this is because bacteria will invade through the cracks, so we must pick out the cracked eggs and put them in the refrigerator to eat as soon as possible. Wipe the remaining eggs one by one with a towel dipped in high white wine.

Eggs without cracks are easy to preserve, and if you wipe them again with Juesen High Liquor to remove the bacteria on the surface, and then put them in the refrigerator for storage, the time will be longer, and they will not be bad for a month.

If you want to keep the eggs from breaking, you can use a fruit net sleeve to wrap the eggs in the process of transportation, and then put them in plastic bags or cartons, or buy special egg trays from the market to store eggs.

How eggs are protected from breaking

1. Increase packaging

nbsp;If you want to keep the eggs from breaking, you can increase the packaging. First of all, the quasi-stuffy and prepare the fruit net, then put it on the surface of the egg, and use a rubber band to tie the mouth on both sides tightly, and finally put the egg into the carton or crisper box.

2. Egg tray protection

nbsp;If you want to keep the eggs from breaking, it is most appropriate to use egg trays for protection. Egg trays are designed according to the shape of the eggs, only one egg can be put in each groove, and the two layers of egg trays are superimposed, which can just fix the eggs inside without shaking, so as to avoid the phenomenon of broken eggs.

3. Foam fixation

If you don't have egg trays and fruit nets at home, using cartons, foam, and sponges can also protect the eggs from breaking. First, put a layer of foam on the inside of the carton, then spread the eggs evenly on the foam, and then use a sponge to fill the gap between the eggs.

1. Egg trays: paper egg trays can be used to protect eggs, and paper egg trays are suitable for large quantities of egg transportation and protection, which is very practical. 2. Plastic egg cartons:

The plastic egg box can fix the eggs well, so that the eggs can avoid excessive collisions, and have a good effect on protecting the eggs. 3. Sponge cushion: Sponge cushion can effectively reduce the degree of collision with eggs, so as to protect eggs.

1. Egg trays: paper egg trays can be used to protect eggs, and paper egg trays are suitable for large-scale egg transportation and are very practical.

2. Plastic egg cartons: plastic egg cartons can fix the eggs well, so that the eggs can avoid excessive collisions, and have a good effect on protecting the eggs.

3. Sponge cushion: Sponge cushion can effectively reduce the degree of collision with eggs, so as to protect eggs.

4. Foam: Foam can play a good role in fixing eggs, and has a certain buffering capacity, which can better protect eggs.

5. Bubble bag: Padding the eggs with bubble bags can also avoid the phenomenon of damage to the egg's belt. You can also use some bran bran, bagasse powder and other powders to put in the eggs, which can effectively prevent the eggs from colliding, so as to protect the eggs.

To prevent eggs from breaking, it is best to put some bubble bags in the container of eggs, which can prevent collisions between eggs, and the phenomenon of breaking the letter and damaging the brothers, or use some bran bran, bagasse and other powders in the container, and then use a soft towel to separate the eggs, which can play a double protective role.

In daily life, when many people buy eggs, the eggs inside are easy to break, it is best to use a bubble bag in each egg to cushion up, and these bubble bags are usually used to hold fruits, so that they can be fully utilized, and the eggs can be avoided from breaking.

If you don't have this bubble bag, you can also use some bran bran, bagasse powder and other powders to put in the eggs, these are also the best materials to prevent collisions, mainly at the bottom of the egg and around the spread of a layer, and then use a layer of soft cloth to separate it, mainly play a double protective role, so that the effect will be better.

Or use rice or beans and other items to isolate eggs, you can spread a layer of rice at the bottom of the container, spread a layer of eggs on top, and then spread a layer of rice or beans to fill the gaps inside, even in the case of collision, the eggs inside will not be damaged.
