Galaxy explosion warning prone to burns, China has to recall

While China - the father's country to confiscate this item and warn people to be cautious about using it, in Vietnam, it is still a "hot" commodity and popular among young people.

Recently, while the ball of light glowing, 7-color ball is still storming in Asian countries, including Vietnam, many social websites and newspapers report on 4 Chinese youth Severe burns due to Galaxy balloons exploding.

Galaxy bubble attracts young people thanks to its unique appearance.

Notably, this type of ball originated from China itself. About 1 month ago, this kind of Galaxy bubble flooded the Vietnamese market with many names such as seven colors, glowing balls, rainbow balls .

With prices not too expensive, about 30,000 VND - 80,000 VND / fruit, it becomes attractive decorative accessories.

In our country, carefree youths use them in party nights. Many young children are met by their parents because they treat it as a normal toy. Demand, its attraction is so great that, when the Christmas and New Year holidays are coming, Galaxy bubbles will burn.

Galaxy bubbles are pumped with hydrogen gas (H ₂ ) with built-in flash bulbs to help create vibrant colors. In order to reduce costs and help high balloons, many small businesses have used impregnated air to pump impurities and soil lamps into H ₂ .

Pictures of Chinese people suffering severe burns caused by Led bulbs exploded.

Talking to PV, Assoc. Nguyen Ngoc Ha - Head of Chemistry Department, Hanoi National University of Education said: The main component soil is CaC ₂ , when added to water to form Ca (OH) ₂ + C ₂ H ₂ . C ₂ H ₂ gas with molecular mass of 26 is only slightly lighter than air (29) so it is difficult to fly high.

Therefore, it is common to add H ₂ gas (very light by mass of molecules 2) mixed with C ₂ H ₂ before injecting into the ball.

H ₂ gas can be created easily in many ways, such as taking aluminum powder (white) or beer cans (the main ingredient is aluminum) with alkaline solutions such as NaOH, Ca (OH) ₂ .

The C ₂ H ₂ gas mixture (lamp and water) + H _{2 is} highly susceptible to explosive explosions with O ₂ gas (in the air) because H ₂ gas is highly flammable, while C ₂ H ₂ reacts with O _{2 gives} birth to a lot of heat causing strong explosions.

When using a light bulb that easily produces heat or sharpness of a ball, the lamp wire that creates H2 gas friction will be reacted causing the ball to explode. Along with that, the decoration of balloons in the party night with candles, cigarette butts are also extremely dangerous.

When bursting the ball, the pressure can be up to 3,000 degrees Celsius, causing danger to the health and life of the exposed person.

According to representatives of the burn department (Green Hospital - Pon), about 10 years ago, every year the hospital also received severe burns due to the explosion of balloons. People should know the principles of burns due to blasting:

1. When burned by blasting balloons, quickly take the victim to soak the burn areas into the water and remove the balloons from the victim.
2. Absolutely do not use toothpaste, python fat . apply to the burn. After the water soaked victim needs to take a thin layer of medical gauze to avoid infection.
3. Do not try to pull out the burns, the deeper the burn will be. Need to quickly bring to the nearest medical facility to ensure there are specialized facilities.
