Due to out of gas : Check gas cans again. 2 Ways to fix it when there is no ignition in a tourist gas stove Step 1: Check the gas cans to see if there is gas or not. If not, you should replace gas cans of reputable brands. Step 2: In case the can has gas, it cannot ignite the gas stove. Think of it as a gas can that has too much pressure (rechargeable cans). Therefore, the safety gas shut-off unit was automatically closed, preventing gas from entering the valve. At this point, you should reset the safety gas breaker. Step 3: In case if the can is still gas and has the correct pressure (new gas can) but still can't ignite. At this point you should check the position of the ignition needle to not be. Remember, the d

1 Introduction to negative ions What are negative ions? Air is made up of a multitude of molecules, atoms, when these atoms or molecules are lost or affected by electromagnetism, they will turn into electrically charged particles, called electrical charges or ions. An ion that carries positive (+) charges when it loses one or more electrons is called a cation or positive ion, an ion that has negative (-) charges when it gains one or more electrons is called an anion or negative ions . Negative ions born in nature Negative ions are naturally formed in waterfalls , or after storms , under the effects of gravity, creating pressures that cause water molecules to decay . In addition, in the forests , the tips of the branches of the trees where photosynthesis takes place, forming the photoelectric effect, causing ionization of the air and the formation of negative ions. Negative ions in nature are also created from thunderstorms, storms ,… Lightning and lightning r

1 What is a brush motor? Working principle Brush motor is a type of motor that uses commutators and brushes to supply current to the coil. This type of motor has coils located on the rotor (located on the rotating part of the motor). This type of motor is very popular today on the market thanks to its low price and simple control. It is commonly used in hand drills, hand rotary tools, toys, etc. Working principle: based on the contact mechanism between the commutator and brush to help supply power to the coil. The brush part on this type of motor is pushed by the leaf spring or coil spring to make continuous contact and slide on the surface of the commutator or the contact slip ring, maintaining the power of the rotor. What is a brushless motor? Working principle Brushless Direct Current (BLDC) motor is a type of motor that works based on a permanent magnetic field and a position sensor, without using a brush (brush) to help eliminate friction and reduce noise. noise for

Instead of boiling eggs with water, try replacing them with granulated salt. In this way, the taste of the eggs is very rich. After the salt is hot roasted, heat can be transferred to the eggs, and the eggs are cooked by the heat of the salt. As a result, the egg will have a crunchier and more fleshy texture, and a richer taste. You can make a batch of many eggs, then the uneaten eggs will be incubated in salt or put in the refrigerator. At this time, the eggs will have a slightly salty taste and will last longer. Ingredients: 10 eggs, 1kg of salt, 1 star anise, 2 bay leaves, 1 piece of cinnamon, 10g whole pepper. Making Roast the salt for 5 minutes over medium heat until the salt is hot. Step 1: Wash each egg under the faucet so that the outer shell is free of dirt and dry with a paper towel. Step 2: Prepare a thick pot, pour salt, star anise, bay leaves, pieces of cinnamon and whole peppercorns. Step 3: Put the pot on the stove, roast the ingredients on medium heat
