Chapter 361: Those who don't understand are basically idiots (8)
"I don't often attend classes. This opportunity is rare. You have to listen carefully. Hee hee!~" Bi He looked at Luo Tuo for letting him wander around like this and returned to his poker face. It seemed that he had to say something practical, "Luo Tuo
Brother Tuo, I really know a little bit about its uses. For example, it can be used to treat diseases and save people, or it can also be used in daily life. For example, we pound the eggshells and put them into thin cloth bags.
Put it in a basin and soak it in hot water for 5 minutes... No, take it out after a quarter of an hour and use this water to wash your clothes. They will be extra white. This method is good, I have tried it."
Ah! The secret was exposed. It was only tried in modern times. She glanced at Luo Tuo secretly. It seemed that she didn't really hear it. Fortunately, she couldn't help but continued with her stomach raised, "The main ingredient of egg shells is calcium carbonate, and a little bit of calcium carbonate."
Sodium carbonate... uh..."
She paused again. Regarding these carbonic acids, Luo Tuo must have been confused.
It’s really difficult to take a class properly. The generation gap in language is so big that I can’t make sense of it.[
really--
"What is calcium carbonate?"
"It's an inorganic compound...forget it, this kind of thing is too scientific and you can't understand it. In short, it's what the egg shell is made of."
"not understand."
"For example, just like a stone, if you put such a big piece in the palm of your hand and squeeze it with your inner strength, it will break into many, many small ones, like sand, and that is also a stone.
But before that, it was a big piece, that is to say, that big piece is made up of many small things."
When Luo Tuo heard this, he nodded, "It makes sense."
"It makes sense, haha! Of course it makes sense, what I said are all facts. It's easy to understand, and those who don't understand are basically idiots."
"Miss, what is the relationship between stones and egg shells?"
