One pressure cooker can blow up two cars. I didn't know the power of the pressure cooker until I watched the beginning.

And an improperly used pressure cooker can indeed go beyond the scope of a pot and become a "weapon" that threatens the safety of the kitchen and even personal safety.

It's just a pressure cooker.

It can be so powerful.

The novel "beginning" reads: "A No. 45 bus crashed into an oil tanker and there was a violent explosion, and no one on the two vehicles survived."

Wait a minute... I believe the pressure cooker fried the kitchen, but could it be true that it caused a whole bus explosion and caused a tanker explosion?

Do not underestimate the power of the pressure cooker, the bomb made with the pressure cooker is actually a kind of improvised explosive device (improvised explosive device, IED). Pressure cooker bomb is not just a plot made up in the novel, in history, it has really caused a number of tragedies.

The 2013 Boston Marathon bombing was triggered by a pressure cooker. At the scene of the explosion, police found metal fragments and nails, while a high-pressure pot lid was found on a nearby roof. In fact, it was through homemade bombs that caused the serious explosion, killing three people and injuring hundreds more.

And the bomb is precisely through two simple homemade pressure cookers.

When the bomb is placed in the pressure cooker, even if the gunpowder explodes, it will not explode immediately because of the hindrance of the pressure cooker, until the pressure in the pot accumulates to a fairly high level. In this case, in the event of an explosion, the power will be much more intense than the normal gunpowder explosion.

With this impact, the pressure cooker explosion can also cause secondary damage. In the Boston bombing, the police speculated that in addition to explosives, the pressure cooker was filled with nails and metal fragments. In the explosion, these fragments will fly out with a high impact, which also caused serious damage to the crowd.

The tube bomb (pipe bomb) uses this principle to produce a serious explosion through a sealed pipe filled with explosive material.

Understand why pressure cookers explode.

It will prevent it from exploding.

In the beginning, although the pressure cooker aunt looked unattractive, she was not found in previous cycles. But everyone who has finished the show may realize that the pressure cooker is indeed a weapon that can do great damage, and it is easy to control and can be triggered with a simple alarm clock. No wonder there is a psychological shadow after watching it:

"when I see a pressure cooker on the bus, I may be stressed: master, get out of the car."

If you think the pressure cooker bomb is far away from our lives, then the fancy explosion method in the "pressure cooker explosion" group must be an eye-opener. One second, it may just be on the gas stove, and the next, after the explosion, it becomes a weapon, a UFO, or a soaring rocket.

The pressure cooker is easy to use, mainly because of its good tightness. When the water is heated into steam, it cannot be discharged, which will make the pressure in the pot higher and higher. The boiling point of water will be affected by air pressure, when the pressure increases, the boiling point will be higher, so the temperature in the pot will be higher than 100 ℃.

In a high-temperature and high-pressure environment, water vapor transfers high calories, and the speed of cooking food will be much faster. Especially at high altitudes, where the boiling point of water is low and food cannot be cooked, a pressure cooker can be used to compensate for the low air pressure.

In order to ensure safety, there is usually an exhaust valve on the pressure cooker lid. When the pressure cooker reaches a certain pressure value, the heavy hammer will be lifted and steam will be discharged.

However, if the pressure of the pressure cooker cannot be discharged, it is likely to cause an explosion. Therefore, when using the pressure cooker, we must pay attention to the patency of the exhaust valve. If the food clogs the vent, or if the pressure cooker ages, there is a risk of blowing up the kitchen.

And everyone who has experienced a pressure cooker explosion may not be able to escape the psychological shadow it brings. According to a survey conducted by the New York Times, 37% of American households owned pressure cookers in 1950, but only 20% in 2011. This is partly because of the fear of a pressure cooker explosion, and on the other hand because of other safer and more convenient kitchen appliances.

Both the start and the pressure cooker explosion team are telling you that using a pressure cooker is risky. Be sure to check it before use and read the instructions carefully.

In addition to the pressure cooker, other misbehaviors in the kitchen can also have extremely dangerous consequences. For example, put grapes or eggs in the microwave oven, put flour on the edge of the stove, etc. Maybe the kitchen will really "explode" by accident.

Usually look at the experience of others, can also avoid the danger of their own kitchen. | | Screenshot of Douban

I hope everyone can use the kitchen correctly and do not have the opportunity to contribute to the "fried kitchen" group. Say the important thing three times: safety first.

No kidding, please use the pressure cooker safely!

1. Refer to the instruction manual

two。 When capping, check whether the vent is open or not.

3. Foods that are easy to expand (beans, porridge, etc.) are recommended not to exceed half of the pot to prevent them from clogging the vents.

4. Pressure cookers that do not have to exceed the fixed number of years (8 years) or are too cheap and have no safety guarantee.

5. Unauthorized pressurization, opening the lid halfway, ignoring the heat, not tight lid and so on are all prohibited behaviors.
