I've been drinking with my mom
One day, my mother came to me, bought dozens of pounds of grapes and shouted for wine. I'm interested, too, and i followed my mom to help her. When a mother crushes grapes one by one, puts them in a jar, spreads a layer of sugar on the surface, then wraps them with a plastic sheet and seals them up。
Two days later, when the smell of wine came out of the house, i was curious, and i wanted to open up the lid, and my mother immediately stopped me: "no cover, no fermentation." "close? Why?" "check it." i opened the computer right away to find out。
Previously, in order to reduce oxygen in containers, sugar was transformed into ethanol in an aerobic environment, i. E. Fermentation, and grapes into delicious wines。
After a month, the wine can be sealed. Mom's happy to have a taste of it while eating. Of course, i've got some light. I've tasted sweet wine. And just the next night, when mom was about to drink some more, she found out that the lid was not on, and she beat her head in a humdrum: "hey, it must have been on yesterday's wine when she forgot to cover it, and the wine `out of breath'." "what's going on?" mom explained it to me. But what's the science in this? In order to understand this question, i once again invited my computer man, who used to volatilize ethanol in the air, so the wine tasted less and sour。
Science is closely linked to our daily lives, and many common senses of life can be answered by scientific knowledge。
