Lin Xianyu thought that his fixed task this month had not yet been completed, and saltpeter was also very expensive, so he simply bought a large amount of saltpeter with silver.

This saltpeter was a medicinal herb in ancient times, which could be used medicinally, which was very convenient for Lin Xianyu.

Just buy it outright.

When Master Lin saw that his daughter had somehow bought back a pile of saltpeter, he was a little puzzled.

"Envy fish, what are you going to do here?" Master Lin watched Lin Xianyu busy before and after.

"Dad, just wait." Lin Xianyu said with a smile.

Even Mrs. Lin was a little curious, what was her daughter going to do, on such a hot day, Mrs. Lin didn't want to move, but seeing Lin Xianyu so busy, she couldn't help but look good.

"Mother, you wait, you can cool down in a while."

Lin Xianyu looked at Mrs. Lin, who was still sweating profusely with two maids, and was also a little distressed, because she was pregnant, she was getting harder and harder.

Lin Xianyu took a small basin, put it half full of water, and then put the small basin into the large basin, then placed the raw nitrate in the large basin, and then poured water into the large basin.

Then everyone saw a very magical scene, but after half an hour, the water in the small basin actually froze.

"Envy fish, how did you do this?" Mrs. Lin was a little curious, and the proximity to the big basin for making ice also made Mrs. Lin feel a burst of coolness.

"Mother, stay away, lest the cold invade."

Lin Xianyu didn't expect that this ice-making was actually easier and smoother than he imagined.

At first, I just made a small pot at random, intending to try it a few more times, but I didn't expect it to be done once.

"Miss, this is a miracle." The people under the maid also sighed.

"Envy, how did you do that?" Even Master 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 was helpless for a while, she didn't want to be a goddess.

Directly started a popular science class.

"This is because saltpeter absorbs heat when dissolved in water, and the temperature decreases, so the water in the small basin freezes."

"I also discovered it by accident, and this method of making ice can also be used by everyone."

Lin Xianyu smiled and said, "This is not a magical thing. ”

"By the way, mother, you are pregnant now, you can't get cold, go back and I'll make a few big ice cubes, put them in the four corners of your room, and then move out when the room is cold."

Lin Xianyu hurriedly pulled away Mrs. Lin, who was a little curious and wanted to see the ice cube.

Soon Lin Xianyu asked the people to help make ice, and the people could make ice, although the awe of Lin Xianyu disappeared, but he still felt that his eldest lady was really magical.

Lin Xianyu was also a little crying and laughing.

And Lin Xianyu also used the snow water he saved last year to make tea, and planned to make some cold desserts to eat.

I took the cream that made the cake, added all kinds of crushed fruits, jam and milk, and finally broke the ice cubes, which looked like ice cream.

Lin Xianyu looked at the colorful desserts in the small bowl with satisfaction, scooped a spoonful with a spoon, and put it in his mouth, satisfied.

It's finally summery.

Lin Xianyu was satisfied with the room with a big ice cube in the corner, eating sweet and sour ice cream, feeling that he had finally come back to life. Take a hundred plating to read the latest chapter of "Salted Fish Koi's Loser's Daily Claw Book House" for free reading for the first time.
