[Rose] Xiaohong and Xiaoqing left the diving paradise after diving with Xiaohong's father, picked up Xiao Orange, and then came to the Science Museum together. See what problems they encounter, and then how they use the invention principle of "inert environment" to solve them cleverly.

The full text of [Rose] takes about 10-20 minutes to read.

[Rose] If you only need to understand the principle of invention, you can read the red font and yellow shading part, which takes about 1-3 minutes.

"Wait a minute, sir!" After treating the wound, Xiaohong's father prepared to take Xiaohong and Xiaoqing out of the diving paradise. As soon as they stepped out of the door, they heard the voice of the waiter who came running behind them.

The waiter ran up to them and said breathlessly, "Hello, sir, thank you for visiting the dive park." Just now when you were treating the wound in the infirmary, our leader happened to pass by the infirmary. After he learned that you had injured your palm in our dive pool, he asked me to come over and apologize to you. The waiter said.

"Thank you for your leadership's concern! In fact, my palm was injured yesterday, but today I did not protect it when diving, and it became more serious. I would also like to thank you for the handling of your infirmary. Little Red Dad said.

"Anyway, this is something that happened in our diving paradise. Our dive park attaches great importance to every customer. Just now our leader learned from the infirmary that this 'wound protection agent' can help you recover your wounds, so we specially let me take a bottle and run to you to give it to you." The waiter handed a bottle of "wound protection agent" to Xiaohong's father and said.

"How does it protect the wound?" Little Red Dad asked.

"Because there are more active things in the water of the dive pool, they are constantly playing with the human tissue at your wound, so your wound becomes serious." Wound protectors' are made with something lazier. After it is sprayed on your wound, it will adhere to your wound in a regular manner and will not play with the human tissue on your wound, so your wound will get better quickly. The waiter replied.

"It was originally made of something lazier, so it must be useful." Xiaohong's father opened the "wound protection agent", sprayed it on the wound a few times, and said, "Thank you so much, your service is really good." In the future, if someone asks me where it is better to dive, I will definitely tell them that you have the best here! ”

"You're welcome, then you walk slowly, I wish you a speedy recovery from your wounds, goodbye." The waiter said.

Xiaohong left the diving paradise, went to Xiao Orange's house to pick up Xiao Orange, and then came to the Science Museum together. The Science Museum has more than ten floors and is composed of more than ten small museums, including the Physics Hall, the Chemistry Hall, the Human Body Function Hall and the Science Popularization Hall. Xiaohong entered the door of the Science Museum, and what they saw was a large screen in the hall, which played a wonderful introduction to the Science Museum.

Xiaohong, Xiao orange and Xiaoqing were deeply attracted by the scientific phenomena introduced on the big screen. After watching the introduction video of the Science Museum, they couldn't wait to climb up to the second floor of the Science Museum and start their visit.

"How did the feathers and coins in this tube fall as fast?" In the "simultaneous landing" visit area, Little Orange pointed to the glass pipe and asked.

"In real life, feathers fall more slowly than coins because they are influenced by the air. Inside that glass tube was vacuum, and neither the feather nor the coin had air effects during their descent, so they fell just as fast. Little Red Dad explained.

"Space is like a vacuum, and in space, feathers and coins should fall just as fast." Xiao Qing said.

"Xiaoqing is really smart, and being able to think of space is also a vacuum, which is awesome!" Xiaohong's father praised Xiaoqingdao.

"The iron block inside the glass cabinet on the left is already rusty, so how come the iron block inside the glass cabinet on the right won't rust?" In the "same iron is not the same life" visit area, Xiao Qing asked.

"The iron block inside the glass cabinet on the left is surrounded by air, and there is active oxygen in the air, and they keep playing with the iron on the surface of the iron block, causing the iron to rust; the iron block inside the glass cabinet on the right is surrounded by lazy gas, and they stay in the glass cabinet in a disciplined manner, and do not play with the iron block, so the iron block inside the glass cabinet on the right will not rust." Little Red Dad explained.

"It's like the 'wound protector' you spray on your hand." Xiaohong said.

"Xiaohong is really smart and can find the same place in two different things, which is awesome." Little Red Dad praised Little Red Road.

After reading this article, we will look back at the part of the text marked in red. "Wound protector" is made of something more lazy, it is sprayed on the wound of little red father, it will be attached to the wound in a regular manner, will not play with the human tissue on the wound, so that the wound will be better fast; the inside of the glass tube is vacuum, the feathers and coins are not affected by air during the descent, so they fall just as fast; the iron block inside the glass cabinet on the right is surrounded by lazy gas, they stay in the glass cabinet in a regular manner, do not play with the iron block, so, The iron block inside the glass cabinet on the right will not rust. They both use lazy things ("wound protector" in the example, lazy gas in the glass cabinet) to protect other things (protect the wound in the example, protect the iron block), or use the vacuum method (the vacuum glass tube in the example). Such an inventive principle we call it the "inert environment." There are still many places in our lives where the invention principle of "inert environment" is used. Like what:

The bulb is filled with an inert gas to protect the filament from oxidation;

When welding, use an inert gas as a protective gas to protect the thing being welded from oxidation;

Vacuum-packed food to prevent food from spoiling;

Vacuum packaging of items to prevent items from deteriorating;

Vacuum storage for space-saving.

There are many similar applications in our lives, can you think of anywhere in life where the invention principle of "inert environment" is used?

In life, have you encountered any difficulties or problems that can be solved with the invention principle of "inert environment"?
