First, how did this uncle burn his forehead? People who often surf the Internet know that there is a very hot photo on the Internet, that is, in a very cold place, if you throw a little water into the air, it will freeze in an instant, and because the water is thrown into the air, it will form a certain arc at this time, which is very beautiful from a distance. Many people try this way, and some even choose to try some very cold places in the northeast in order to take good-looking photos. This also makes an uncle look jealous. He also wants to experience the popular trend of throwing water into ice. The uncle took a bowl, put a bowl of hot water in it, and then spilled the bowl of water into the air like others, but in the process of splashing water, he threw the bowl out directly, and the boiling water in the bowl accidentally spilled on his head. Uncle's head fell off because it was boiling water late.

Second, what do you think of uncle's practice? Uncle, this is obviously dangerous. In fact, splashing water into ice can be tried with cold water or warm water, but this uncle chose hot water dangerously because he spilled water on his head because of improper operation. If she pours a bowl of water directly on herself during the operation, the consequences will be unimaginable, and there are certain requirements for splashing water into ice. The requirements for temperature and skills are very high. If ordinary people want to try, the chances of success are very small, and it is very dangerous for this uncle to try just after watching other people's videos.

Third, what are the familiar challenges? In fact, there are many well-known challenges on the Internet. For example, the previous ice bucket challenge was once very popular, and many people at home and abroad tried it one after another, and even set off a trend of ice bucket challenge. Some people will try to lick the iron bars with their tongues in the cold season. Without exception, their tongues are stuck in the iron bars, and then the picture will become very embarrassing. They had to ask others for help to slowly melt the ice between their tongues and iron bars with warm water. Then your tongue can be saved, which is very dangerous. If no one comes to save you, your tongue will probably fail. Secondly, some people will try to put the light bulb in their mouth, because some people just don't believe that the light bulb will get stuck after putting it in their mouth, so they try it and finally go to the hospital for help. These are ridiculous challenges, but some people just don't believe in evil and try their best to do such challenges and experiments. But when doing these challenges and experiments, we must be objective and rational, and we must ensure safety. After ensuring safety, make these attempts.
