Pourquoi y’a t’il un trou dans le hublot de l’avion001

In the excitement of getting on the plane and in the euphoria of traveling again, you surely did not notice the presence of a small hole at the bottom of the window. Next time you board a plane, watch out! Its diameter does not exceed two millimeters, so it is not easy to notice it, but we assure you that it is indeed present for a reason that you still do not know.

In an airplane cabin, no detail is left to chance. The hole in an airplane window therefore has a very specific function. Find out which one.

What is the small hole in the airplane window for?

The function of the small hole in the airplane window is so important that it is considered essential for travelers: in short, this hole regulates the pressure between the inside of the cabin and the outside. Outside, the air is less pressurized than at low altitude; Inside the plane, pressurization allows you to breathe tolerable levels of oxygen.

The hole in question is called a “breather hole” and is located between the first and third layers of glass in the window. It is clear that the outermost glass has to bear most of the pressure load because it is in contact with the outside air. The innermost panel, that is, the one in contact with the passengers, protects the other two layers while the central one, where the hole is made, allows the air that passes through it to be pressurized. This means that the air strikes a perfect balance between inside and outside.

In other words, this hole diverts most of the pressure coming from the outside and makes it possible, in the event of a break in the outermost layer, to keep the cabin under pressure. In addition, it has the function of not fogging up the windows in flight and not creating dangerous condensation.

In short, do not be scared by this hole… it is not an anomaly at all, quite the opposite. For our own safety, it is good not to cover it up or cover it up because.

The plane has even more mysteries that are important to unravel. For example, do you know why the lights go out when taking off?

Why do the lights go off when taking off?

Pilot Chris Cooke revealed to Travel+ magazine that the lights go out upon takeoff to ensure passengers’ eyes adjust to the dark in case of danger or emergency operations.

“Imagine that you are in a bright room that looks familiar and full of obstacles. Suddenly, someone turns off the lights and asks you to get out quickly”: surely you would have more difficulties in this situation than if you had had the necessary time to familiarize your eyes with the lighting and the environment around you.

Not to mention, if an impromptu emergency landing is required, the dark interior of the cabin would highlight the lights leading to the emergency exits faster and better.

However, although these measures may seem “strange” to us, their mission is to reinforce security on board.

How to prevent boiling water from boiling over: simple and practical tips

L’eau bouillante ne débordera plus de la casserole grâce à l’astuce des chef0011

It is well known: to prepare a recipe based on pasta or rice, it must be immersed in a large volume of boiling water. But very often, our pan always ends up overflowing… Don’t panic! We reveal the advice of Thomas Langevin, chef of the Aude to avoid this unfortunate inconvenience and succeed in your culinary preparations on time.

add oil to water

When you boil vegetables, rice or pasta, you notice the formation of a foam on the surface of the water. In heat, the bubbles exert pressure, often causing spills.

To avoid these inconveniences, add oil to the water, it acts well on the foam, preventing it from forming. This will prevent the water from overflowing. Remember that it is important to act at the right time, so add the oil from the beginning of cooking.

Sometimes it also happens that water spills out for a simple reason – long-term use of a lid on the pot. This tool certainly saves time by heating the water more quickly, but it prevents the escape of water vapor.

Use a wooden spoon

There is another very simple and equally effective trick to prevent the water from overflowing from the pan, place a wooden spoon and that’s it!

The wood acts as an insulator. The bubbles that form when the water boils will thus be reduced thanks to the contact with the wood.

Why does pasta water foam?

Pasta is made from flour, water, and sometimes eggs, starch, and protein are dried and stored in it. When you put them in boiling water, a hot and humid environment, the starch continues to absorb more and more water until it bursts. The result is that the starch molecules are pushed into the water, creating the foam you see.

The starch also causes the pasta to stick together in the middle of the cooking process, so you need to stir occasionally to prevent a giant dough from forming. Once the pasta has finished boiling, the water becomes saturated with starch. So adding a bit of this water to your seasoning will allow the sauce to adhere better to your pasta.

Rice is a staple in many kitchens. It is very simple and easy to prepare. However, when cooking, boiling water can quickly overflow. This is the best method to prevent the rice from boiling over and sticking.

  • Rinse your rice in several changes of water to remove excess starch.
  • Place the rice in a larger pot. This trick simply allows larger bubbles to form so that the liquid properly covers the beans.
  • After boiling, reduce the heat to very low.
  • The rice may take a few more minutes to cook.

If it often happens to you that the rice sticks to the pot, add vinegar during cooking. The effect is achieved by its high content of acetic acid.

To use it for this purpose, once the water starts to boil in the pot, add a little apple cider vinegar and wait for it to come to a boil again. When you add the vinegar, lower the temperature for a few moments. Then we add the rice and cook as usual, controlling the intensity of the heat and stirring from time to time so that it cooks evenly and thus does not stick or burn.

Use a sponge to thoroughly clean the entire hood. Then rinse the sponge to clean the hood again. Finally, dry the surface with paper towels or a dry kitchen towel.

  • Vinegar Water to Fight Hood Grease

  • Olive oil for a clean cooker hood

As it turns out, olive oil can have many uses in a kitchen, especially cleaning the range hood. First, apply a small amount of oil to the entire surface of the hood using a sponge. Then cover it with a microfiber cloth soaked in warm water. After a few minutes, scrub everything down with a sponge and wipe clean.

  • A dishwasher tablet for a hood like new

To avoid the accumulation of grease and dirt in the hood, clean it with a mixture of hot water and dishwasher tablets that will melt. Begin by spraying the areas to be cleaned. Let the solution sit for 30 minutes to 1 hour, depending on the amount of embedded dirt. Then use a damp cloth to easily remove the grease.

  • Baking soda for a clean hood

Baking soda is our best ally in many household tasks. It has strong cleaning properties as it is a caustic substance. First, bring the water to a boil in a medium saucepan, then add two tablespoons of baking soda. The mixture will start to foam after a few minutes, this means it is ready to use. Use a sponge soaked in this foam to carefully clean the entire surface of the hood and vent. If the entrance is too narrow, clean those hard-to-reach areas with a toothbrush. Finally, dry the entire hood and grill with paper towels or a microfiber cloth.

  • Salt and limestone for a nickel bell.

For effective cleaning of your cooker hood, use a solution based on salt and limestone by mixing the ingredients in hot water. Apply the mixture to your hood with a soft cloth, then rinse and buff for a flawless result.

  • Lemon to clean the hood

To clean your range hood, boil water with lemon or lemon juice. Turn on the range hood to draw in the steam for 15 minutes. After that, wipe the hood with a soft cloth, rinse and wipe it.

To clean your cooker hood filters that are clogged with grease, you must first remove them using the retaining clip located on the front or side depending on the model. Prepare a cleaning bath in your sink or bathtub, then submerge your filters in it. You can soak them in a solution of boiling water, baking soda, and dish soap for 30 minutes, or use a mixture of boiling water and black soap shavings. Once the filters foam, use a soft brush to scrub them, rinse them with clean water and let them dry. Once clean, the filters are ready to be used again.

For the final maintenance of your hood, clean the exterior walls. Dampen a soft cloth with isopropyl alcohol and gently wipe the entire device to restore its shine. If your range hood is a traditional range hood with a chimney covered with plaster or wallcovering, use a small vacuum brush to remove any dust, then wipe with a damp cloth and some mild cleanser.
