So, are these products really useful?
A reporter from the Beijing Youth Daily contacted several consumers who bought Internet celebrity spray. According to a Chengdu netizen Xiaoka, he saw many people who saw Amway’s cool artifact of the Internet celebrity and bought a bottle of it. Shop bought.

However, some netizens suggested that I dump the liquid inside and bury it in the soil, and then put the bottle. Throw it away".
survey
Cooling spray contains ethanol and liquefied petroleum gas
Avoid smoking immediately after use
Experiments conducted by the Fire Fighting Detachment of Enshi Tujia and Miao Autonomous Prefecture in Hubei Province showed that when a spray of a cool artifact is sprayed into a bowl and lit with a lighter, the open flame burns as soon as it approaches.
Firefighters said that there are LPG (liquefied petroleum gas) components in this spray, which is not only flammable, but may also explode if left in the car for a long time.
A reporter from the Beijing Youth Daily learned from Huang Zhiyan, head of the Shougang Winter Olympics Fire Station of the Shijingshan Fire Rescue Detachment, Beijing. It is flammable and combustible. "I also searched several high-selling cooling spray products on the Internet, and found that, except for some products whose ingredients are LPG, most of the other main ingredients are ethanol, commonly known as alcohol, and its ingredients are also flammable. "
Huang Zhiyan also suggested that cooling products such as ethanol actually make use of the physical properties of such things-volatilization and heat absorption to form a cooling effect.
When purchasing cooling spray products, citizens must carefully understand the specific ingredients. If flammable and combustible products such as ethanol and liquefied petroleum gas are involved, they must be kept away from fire sources. High. In the past, simple lighters have been placed in the car and there have been cases of fire. This cooling spray product is also dangerous. After using the cooling spray product in the car, you must avoid smoking and other behaviors immediately to prevent fires." Huang Zhiyan Say.
remind
Power bank, perfume and other items
Don't put it in the car in summer
The fire department reminded drivers that not only this kind of cooling spray artifact has fire hazards, but also in the high temperature in summer, do not put power banks, perfume, reading glasses and carbonated drinks in private cars.
The fire department explained that the power bank is a battery product. Such items will bulge and explode if left in a car with a high temperature for a long time. Especially some low-quality power banks, using unqualified lithium batteries or modified batteries, are stable. worse.
Do not put the lighter in the car, especially in the place where the instrument panel is exposed to direct sunlight.
This is because the lighter contains liquid butane, and the temperature exceeds 55°C, the internal pressure will increase, which will cause the lighter to burst, and in severe cases, it may burn the car.
The main components of perfume are essence, alcohol and moisture, and the alcohol content is between 40% and 80%.
When the vehicle space is confined and the air is not circulating, a flash explosion will occur if it encounters an open flame or a combustion-supporting object, such as a cigarette lighter.
Convex lenses such as reading glasses and magnifying glasses can condense light and generate high temperatures, which can easily cause fires over a long period of time. Such items must be placed in a place not exposed to sunlight.
Under high temperature irradiation, the aerosol freshener is easy to vaporize, and the pressure rises sharply, which exceeds the pressure strength of the tank body and explodes.
In addition, when the temperature inside the car is too high, carbonated beverages are also prone to swell, causing bursts.
