Chapter 1692

"Ha ha, that's good enough. If it's not enough, you can talk to dad again and dad will do a little more."

"Mm-hmm!" Zhao yun'er answered.

Zhao Yuner first polished the wood on the ground, then took out the nails and nailed the boards together with a small hammer.

It took an hour to make a wooden box.

Zhao Yuner specially added several layers around the wooden box to make the box more airtight.

As for the inside of the box, Zhao Yuner made some more paste and sealed the surrounding of the box with some sand, so as to protect the box from ventilation. Ice cubes don't melt as quickly as they do.

The box is not big or small. It can put a lot of vegetables in it. It's got a lid on it. Just put it on.

Zhao Wenhua and Liang Jinqiao stare at one side and see that Zhao Yuner has been doing it for a long time. Finally, he only gets a box out, which makes him more confused.

"Can the leftovers in this box keep the leftovers from spoiling?" Liang Jinqiao couldn't help asking.

Zhao yun'er was amused by Liang Jinqiao, "of course not! Mother, don't worry, I'll find out later! Ha ha

Liang Jinqiao replied, "ha ha, OK, my mother is waiting!"

Zhao yun'er took the box to the outside and dried it. The sun was shining on the hot day. After a while, the paste on the box dried up.

Zhao yun'er looked at it and began to take out the saltpetre and make some ice.

The thick ice broke and spread in the box.

Zhao yun'er then took the cover and covered it and found the broken quilt that the bed didn't want.

"Dad, mom, that's it!" Zhao yun'er said with a smile.

Liang Jinqiao and Zhao Wenhua looked at each other for a few times, "isn't it easy to melt the ice in it? This big hot day, still cover the quilt, not melt faster

"Yes, yun'er girl, do you want to save the ice for one night? Even if you put the food in it, I don't think it will last too long. "

"It's waiting for the ice to melt, the food inside is not so cold, and the food is rotten again!"

"Yun'er girl, are you sure this is really OK?"

Zhao Wenhua and Liang Jinqiao, you and I said one by one, it seems that they do not believe that the box will be so magical.

One night the ice is put in it, and it will melt into water in a short time.

"Mother, don't you know that? The quilt will not let it melt, but also let it turn slowly! "

"This How could it be! " Liang Jinqiao muttered.

"This quilt is used for heat preservation. It's cool inside. The cool air will be fixed. The hot air outside is not easy to get into." Zhao Yuner explained.

"So? Does that really last a night? "

Zhao Yuner nodded, "it should be possible! After one night, we'll just keep getting some more ice in the next day. If you put the food in it, it must be rotten. "

"Let's try it tonight."

"Ha ha, good!"

Zhao Yuner is very confident about his simple refrigerator.

If you make this refrigerator, you can make a few more later. You can send one to Mulan's house. Your family can use it.

Seeing the simple refrigerator, Zhao Yuner can't wait to make some herbal tea and other things.

It's very easy to get heatstroke in this hot day. It's good to make some iced mung bean soup.

Last time she went to Yangcheng, she bought a lot of mung beans back. She hasn't cooked them yet. Today, she can cook some of them for you to taste.
