Who can tell me a story about a high school chemistry experiment? It is interesting and true, and there is no objection to copying and pasting. As long as it is useful, it is about 1000 words.

First of all, I want to explain briefly here: several students in this class and I will go back to the chemistry lab to do experiments almost every noon. This article is about what happened in our chemistry lab.

The fish lit and covered the alcohol lamp.

First of all, I want to remind you that if you want to see how the fish lights up the alcohol lamp, please prepare a box of matches and a pair of tweezers. If you want to see how the fish put out the alcohol lamp on a whim, please take out your personal insurance first, and please stand back two meters under protection. Remember, remember!

I'm not very good at describing it, so I'll make do!

..... after searching everywhere, the fish shouted, "Who has taken my alcohol lamp?" "I didn't take it!" "Your alcohol lamp is not good for yourself!" ..... The fish really couldn't find the alcohol lamp, so he got angry and went to the next room to get the alcohol lamp. ..... I saw the fish put the alcohol lamp on the table, took out the matches from the matchbox and began to strike. Once, twice, three times, four times, no; Five, six, seven, eight, broken. There is an exaggeration in this, because when a fish cuts off one or strokes more than five times, someone will find it and help him light the alcohol lamp in time.

At first, fish had to use tweezers to help them strike matches, that is, to record matches with tweezers. The reason is simple: they are afraid of burning their hands!

Let's describe how the fish covers the alcohol lamp.

Look, the fish slowly picked up the alcohol lamp cover. I don't know who found it, but I added: "The fish is going to cover the alcohol lamp!" "Everyone back. Because the fish should be fully prepared before turning off the alcohol lamp, which gives us time to retreat. When I saw the fish in my belly, I held my breath and covered the alcohol lamp with lightning speed. As soon as the lid reached the flame range, it was put away twice as fast as before, and the result was predictable (not extinguished). Fish oil began to repeat the action just now. We have been laughing from ear to ear ... finally we argued with the fish for the lid of the alcohol lamp, and then we helped to cover it. Fish is very strong and generally won't accept our help, but we still have to help him for our own safety.

As for why we need to buy personal insurance, it's because once the fish covered the alcohol lamp and spilled alcohol on the table, which really made us nervous. And the fish is all soft and at a loss! I still remember that expression.

Funny hair

This is also a story related to alcohol lamp. Doing the experiment that day, Zhuang lit an alcohol lamp, but Xiao didn't notice it. When I smiled and poked my head out to look at the experimental device, I only heard Zhuang shout, "Burn!" " Laughter seemed to be felt, so we quickly raised our heads. We looked at the smiling hair and smiled. Although it's nothing serious (fortunately, it's not hairy), it's also burnt and some are yellow. Postscript: One day, the teacher talked about the phenomenon of burning pure wool products and asked, "Has anyone ever permed their hair?" We all looked and smiled, and replied, "Laugh …".

The scream of fish

Fish is often the source of our jokes in the laboratory (mostly because of his cowardice). One day, we just laughed our stomachs off because the fish put out the alcohol lamp (see the story in the chemistry lab (1)), and then a shocking and ridiculous thing happened. The teacher was making nitrogen dioxide that day, and we all ran to the preparation room to see it, while the fish stayed in the laboratory to concentrate on his experiment. Just as we were absorbed in observing this phenomenon, we heard the sound of fish in the laboratory. We were all surprised and ran to the laboratory only to find that the fish was at a loss with a pair of tweezers. Finally, he came to his senses and told the reason: he thought that a piece of metal on the table was aluminum, which was burned on the alcohol lamp on the sidewalk (aluminum can't burn in air), but it was actually magnesium (magnesium can burn violently in air). When the fish didn't expect this, it trembled on the table. With the fish's screams, magnesium burned on the table, so there was the scene just now. Why don't fish throw away tweezers? laugh ........
