Since there is gunpowder, firecrackers are necessary! There is no need to burn bamboo during the Chinese New Year.

When I heard that Li Chenghua wanted to make firecrackers, everyone became excited and asked how to make this incense? What materials should be used for it? When can it be done?

Li Chenghua said impatiently: "Okay, stop chatting, like a chick. Just look at it and you will know. Let's start, and you have to watch the fun!"

Next, Li Chenghua asked someone to boil water.

A large pot of water quickly boiled, and then Li Chenghua poured the water into a pool.

There are some powders in the pool, which are mixed with elm bark and wood powder. The elm bark is very sticky and smooth. The barks are dried and crushed into powder. Add ordinary wood powder to mix them to make the aromatic raw material.

After pouring boiling water into the pool, Li Chenghua took a wooden board to stir, and slowly the wood flour mixed into something like plasticine!

At this time, Li Chenghua tried the heat and said, "The sole massage has begun. Whoever wants to come will come!"

After saying that, Li Chenghua took off his shoes, slowly walked into the pool, and stepped on the wood powder.

Wu Mei said strangely: "Brother Chenghua, what are you doing?"

Li Chenghua smiled and said, "This way of trampling can completely combine wood powder and water, otherwise the wood powder will be uneven and the fragrance produced will be easily broken!"

In the 21st century, Li Chenghua's family was from the countryside and had seen how to make incense. Unexpectedly, when he returned to the Tang Dynasty, could this technology be used?

Li Chenghua said, grinning and said, "It's so hot, my feet are cooked!"

Liu Ruiting said curiously: "Brother is so hot? I'll come too!"

After Liu Ruiting said that, she took off her shoes and jumped in.

As soon as she jumped in, she screamed and jumped out! Then she hugged her feet and shouted: "It's so scorching! My feet!"

Lee Seung-hua smiled wickedly and said, "It's a reckless thing! You're at a loss now? Take your time. Try to step on it with your heels, otherwise the wood powder will squeeze into the middle of your toes, which will be very hot and painful!"

Liu Ruiting nodded, looked at how Li Chenghua stepped on it for a while, and gritted her teeth and jumped into the pool again. This time she persisted for a long time.

Next few girls went on stage and stumbled! Wu Mei was the smartest and lasted the longest time.

After dozens of minutes of trampling, Li Chenghua agreed. Then he grabbed the wooden powder plasticine one by one, grabbed it into steamed buns, and threw it onto the linen.

Several girls also learned to him to grab the wood flour. Wu Mei said, "Brother Chenghua, sometimes I feel that there are some particles in my hands. Can I grab it like this? Those wood flours that are not fully combined will be better combined?"

Li Chenghua smiled and said, "You can teach me! Oh, it should be a beauty who can teach me! This is the principle. You have to take it out and dry it later. After it is cold, you have to step on it again, and then the ingredients will be ready, so that you will start to make fragrant!"

After a few dozen minutes, the completely cooled wood powder was poured into the pool again, and Li Chenghua still went in and stepped on it.

He stepped on it and said, "Hey, I'm so cold, it was very hot just now, but now it's cold!"

Half an hour later, Li Chenghua said that his mission was done!

Then he used a sickle to separate the "plasticine" into pieces, then made into a cylindrical shape, and finally placed it in a circular metal bucket, which looked like a piston.

A piece of wood is stuffed on the piston. Then, use the lever principle to press the wood plug. There is a small hole under the piston, and the fragrance of vermicelli will appear inside.

The girls were stunned. It turned out that this is how Xiang came out? However, they didn't understand what the principle of leverage is.

Lee Seung-hwa smiled and said, "It's time to start, look at me!"

After saying that, he picked up the vermicelli-like things and placed them one by one on a wooden rack.

There is a layer of cloth like a mosquito net on the wooden rack. These incenses must be kept outside the door in sunlight for a day before they dry. Then pick up the incenses from the cloth!
