What should children pay attention to when playing with balloons?

At the gates of parks and kindergartens, many people are selling inflatable balloons, such as Meiyangyang, Pleasant Goat, Mickey Mouse and Hello Kitty .......................................................................................................................................... Don't blow too hard The bigger it is, the thinner the rubber is and the easier it is to break. Don't let the baby hit and kick the balloon as a ball, which will easily make the balloon explode. After the balloon explodes, clean up the debris to avoid being accidentally stuffed into the mouth by the baby. In crowded places or places with high temperature, such as cars, air should be released to prevent balloons from bursting due to extrusion or high temperature. Hydrogen balloons must be kept away from open flames to prevent explosion. Don't take the bus or subway for hydrogen balloons to avoid static electricity caused by friction explosion. Moreover, the bus company expressly stipulates that flammable and explosive materials cannot be carried on the bus, and hydrogen balloons are flammable and explosive materials. The temperature is high in summer and the static electricity is high in winter, so it is not suitable to play with hydrogen balloons, because when hydrogen and oxygen are mixed, the spark generated by static electricity is likely to cause the balloon to explode, which is very dangerous.

When the temperature reaches the ignition point, the hydrogen balloon will also explode. According to the balloon management measures issued by the National Meteorological Administration, helium should be used instead of hydrogen when inflating balloons, because helium is an inert gas and will not burn and explode, but the price of helium is more than 10 times that of hydrogen. Many manufacturers often use hydrogen instead of helium in order to obtain greater profits. The balloon filled with hydrogen is actually a dangerous "bomb", because when the baby plays with the balloon, don't let it near the kitchen or high-temperature objects such as coal stoves. Balloons are plastic products that are blown into a thin layer by air. It will crack or even burn at high temperature. After the mixture of hydrogen and air reaches a certain proportion, it may explode due to static electricity or open flame with a little carelessness.
