The play was a great success.
In two weeks, there were three performances of "Cinderella", and many people saw it more than once. If the first performance was because of the publicity and notice, then the next two performances were completely spontaneous. There were even people who went to the City hall to ask when the fourth performance would be.
Such a response made Roland overjoyed. Everyone was completely attracted by the story, and almost no one raised any objections. Why was it a witch who helped Cinderella? Next month, when the "Rooster Crows at Midnight" would be performed, it would be almost exclusively for the poor people. He didn't know what the serfs would think of the witch who helped them in the play.
Another good thing was that the crew settled down in the town and accepted the existence of witches. After the three performances, Irene took the initiative to find Roland and asked him why there was a sudden sound accompaniment during the performance, and Roland introduced Echo to her.
Under Nightingale's secret observation, although Irene was surprised, she didn't show any disgust or disgust. Instead, she seemed very curious, asking Echo all sorts of questions and making her demonstrate the sound illusion several times. As a result, Echo also joined the crew and became the master of music behind the scenes. In order to avoid accidents, Irene only rehearsed alone with Echo when she needed to match the sound effects, and the rest of the crew didn't know about it. There was no doubt that the next play would reach a new high in the richness of the sound effects.
Another good thing was that the castle was about to usher in the era of running water.
The towering water tower stood in the castle's backyard. The tower was made of welded iron frames and was triangular in shape. The top of the tower was connected to an iron bucket with a diameter of two meters and a height of three meters. There was a float valve in the bucket, which could easily control the height of the water. The tower was welded by Anna, and then covered with an anti-rust coating by Soroya. Finally, with the help of Hummingbird, most of the weight was reduced, so that it could be installed on the pre-poured cement base.
Due to the height of the castle, the water tower in the backyard was higher than the one by the Redwater River. It was close to 12 meters, almost level with the top of the castle. In order to prevent it from collapsing, Roland also added a wall connection to the water tower, so that the water tower and the castle were connected as a whole.
The steam engine was located outside the backyard and used to supply water to the water tower. The water source came from the well in the backyard of the castle. This was the third generation of steam engines, and the biggest improvement was the reduction of noise pollution.
Gaskets were installed on every connection point of the steam engine. These light blue gaskets were the same color that Soroya used to paint the sky. They were very soft and tough, which greatly reduced the vibration and noise of the machine. The inside of the cylinder and the edge of the piston were covered with the color of grass to reduce air leakage and improve work efficiency. The parts that were prone to tremors, such as the exhaust pipes, were all replaced with coated hoses.
In order to prevent the steam engine from being exposed to the sun and rain, and to further isolate the noise, Roland also specially built a small room around it. The walls of the room were painted by Soroya with a layer of honeycomb paint to act as a porous sound-absorbing material. The actual test results showed that even if it was operated at night, the noise of the machine would not wake up the sleeping people in the castle.
However, Roland's attempt to make the steam engine feed automatically failed.His original idea was to use the flyball of the steam engine governor to control the valve of the wooden box. When the steam pressure dropped, the flyball would close and open the valve, allowing the firewood in the wooden box to roll into the furnace. But in this way, the governor must be made very large, otherwise the flyball's weight would not be able to drive the valve. Roland thought about it and decided to give up. The wooden box could only be filled with firewood once, and after it was used up, it had to be filled manually. It would be better to arrange people to fill the water tank with water every day.
The last step was to install the water pipes, including faucets, showers, pipes and the corresponding drainage pipes.
Because the castle was not like the newly built brick houses in the residential area, these holes were left, and the stone roof and walls made the transformation very troublesome. This step took nearly a week. In order to live a happy life, Roland personally directed Carr to transform a room on the second and third floor into a bathroom.
Soroya's new ability once again played a key role. After the drainage pipe was paved with cement, a thin layer of grass was painted on the floor, not only was it waterproof, but when walking into the bathroom, it was like walking on a grassland. Inspired by this, Roland simply let her paint the whole room. The ceiling was an open blue sky and clouds, the four walls could see the distant valley and green grass, and the four walls of the bathtub were crystal clear, just like a gem.
On the day that the water system was put into operation, the Prince called all the witches to the bathroom to experience this great result.
The water tank in the backyard was already filled with water, he turned on the faucet, and the water gushed out along the pipe.
"From today on, there is no need to bring water from the well," Roland proudly announced, "The bath water also doesn't need to be returned every three days, you just need to stand under the shower and pull this switch."
"Huh? Where does the water come from? "Lightning stuck out her tongue and licked the endless water droplets," It's sweet. "
Maggie stuck out her head from under Lightning and did the same, "It's sweet!"
Roland stopped the third Nana who wanted to stick her head closer, "Anyone who wants to drink water must wait until it is boiled before drinking. The water flowing out from here can only be used to wash hands and bathe."
"This is … the Siphon Principle, right?" Anna looked at Roland, her lake blue eyes sparkling.
"What is that?" Hummingbird raised her hand and asked.
Under the training of Teacher Scroll, the witches in the class had now developed the habit of raising their hands and asking questions.
"According to 'Elementary Physics', when the liquid level of two containers is different, the two liquids are connected by a pipe. No matter what the shape of the pipe is, under the action of the liquid's own gravity, there will always be a tendency to keep the liquid level moving." Anna recalled while explaining, "Our position is lower than the water tower, so the water will constantly flow here."
"Absolutely correct," Roland praised. To be able to connect the knowledge she learned with reality, she was indeed a genius.
"What about this?" Nightingale curiously pointed to the shower hanging high up, "Why does it have so many small holes at the bottom?"
Roland turned the valve, letting the tiny water droplets spray out, "For the convenience of bathing. As long as you stand under the shower, you can easily wash your body. "
"So, you've been tossing and turning in the castle for a week, just to make bathing more comfortable?" Lily curled her lips and whispered, "You're indeed a noble who loves luxury."
"Lily!" Scroll said, frowning.
