Lin Xianyu thought that his regular tasks for this month had not been completed yet, and saltpeter was also very valuable, so he simply bought a large amount of saltpeter with silver.
This saltpeter was a medicinal material in ancient times and could be used medicinally. It was very convenient for Lin Xianyu.
Just buy it directly.
When Mr. Lin saw that his daughter had bought a bunch of saltpeter for no apparent reason, he was a little puzzled.
"Xianyu, what are you planning to do?" Mr. Lin looked at Lin Xianyu busying himself.
"Dad, just wait." Lin Xianyu said with a smile.
Even Mrs. Lin was a little curious as to what her daughter was planning to do. On such a hot day, Mrs. Lin originally didn't want to move, but seeing Lin Xianyu busy like this, she couldn't help but take a good look. got up.
"Mom, just wait, it will cool down in a while."
Lin Xianyu felt a little distressed when she saw Mrs. Lin, who was still sweating profusely while the two maids were fanning, because she was pregnant and it was even harder.
Lin Xianyu took a small basin, filled it half with water, then put the small basin into the big basin, then placed raw saltpeter in the big basin, and then poured water into the big basin.
Then everyone saw a very magical scene. After a while, the water in the small basin actually froze.
"Xianyu, how did you do this?" Mrs. Lin was a little curious, and being close to the big ice-making basin also made Mrs. Lin feel waves of coolness.
¡°Mom, please stay away to avoid the cold air from intruding.¡±
Lin Xianyu did not expect that making ice would be easier and smoother than he imagined.
At first, I just made a small pot at random and planned to test it a few more times, but I didn¡¯t expect that it would be done just once.
"Miss, this is simply a miracle." The people under the maid also sighed with emotion.
"Xianyu, how did you do it?" Even Mr. Lin was a little surprised. Although his daughter had invented many things, none of them surprised him as much as making ice in summer.
Lin Xianyu felt helpless for a while, she didn't want to be a goddess.
A popular science class started directly.
"This is because when saltpeter is dissolved in water, it absorbs heat and lowers the temperature, so the water in the small basin will freeze."
"I discovered this by accident. This method of making ice can be used by everyone."
Lin Xianyu smiled and said: "This is not a magical thing."
"By the way, Mom, you are pregnant now, so you can't catch cold. I will make some big ice cubes later and put them in the four corners of your room. I will move them out after the room cools down."
Lin Xianyu quickly pulled away Mrs. Lin who was a little curious and wanted to see the ice cube.
Soon Lin Xianyu asked his servants to help make ice. The servants were able to make ice. Although the awe of Lin Xianyu disappeared, he still felt that his eldest lady was really magical.
Lin Xianyu was also a little bit dumbfounded.
Lin Xianyu also used the snow water saved last year to make tea to make ice, planning to make some cold desserts.
??He directly took the cream for making the cake, added various fruit mince, jam and milk, and finally crushed the ice cubes. It looked almost like ice cream.
Lin Xianyu looked at the colorful desserts in the small bowl with satisfaction. He took a spoonful of it and put it in his mouth, feeling satisfied.
It finally feels like summer.
Lin Xianyu sat contentedly in the room with big ice cubes in the corner, eating the sweet and sour ice cream, feeling that he was finally alive. (Remember the website address: www.hlnovel.com
