Science experiments? There are no instruments on this table, and there are no bottles and cans, how can it be a scientific experiment?

Three-year-old Mia didn't quite understand what the science experiment was all about, but five-year-old Marvin did.

Marven raised his question, and the bearded uncle explained for a long time that Marven still didn't understand. But there was one thing he knew.

The purpose of this experiment is to transport people and things from one bubble to another. That is, people and things can get out of the huge closed bubble that covers the whole city.

The experiment was successful, but there was a problem: there was no problem with teleporting something as light and small as a hair, but something larger than a hair and heavier than a hair would fail.

That's why the girl in white and the bearded uncle are interested in Marvin and his little buddy.

Although Marven told Uncle Beard that they were using his grandfather's old cane for interstellar travel, Uncle Beard said that interstellar travel was not a problem, the problem was how to travel into the bubble. So Marvin and Grandpa's old cane doesn't solve the problem that Uncle Beard encountered.

"So how can we solve the problem?" Marven asked.

"I know the solution, but I don't know how to do it. I need to generate a huge amount of electricity in an instant. The stronger the electrical energy, the greater the ability to transmit. ”

Marven thought for a while and said, "Isn't it okay to use the electricity in this city?" ”

"Lines are lines. However, it is necessary to collect the electrical energy and discharge it once. ”

Marven didn't understand what it meant. However, he knew that there was a lot of energy on Earth that was stronger than electricity. Things like earthquakes, hurricanes, and tsunamis are the energy on the ground. And the stronger energy is in the sky, and that is the solar energy. It is said that the energy of the entire earth combined is less than one billionth of the sun's energy.

Marven pointed to the sun in the sky and said, "Can you use solar energy?" ”

Uncle Bearded glanced at the sun and said, "I understand what you mean." Solar energy can be used on other planets. But not in our bubble stars. Because we are now below the surface of the sea, the sun does not shine in. The sun in this bubble is artificial, and it's actually a big light bulb. ”

"Oops! Worst! Marven yelled.

"What's wrong?"

Marven said, "If that is not the sun, then the night we encounter is not the real night." If there was no night, it would be impossible for Grandpa Cane to recover his energy, and he would not be able to take us on a journey through the stars. ”

"Yes."

"Also, the solar panels on the off-road vehicles can't be charged. I'm going to have to go down and tell Whiskers to stop running around before it runs out of battery. ”

"Batteries? What did you just say? Battery, you say? Uncle Beard's eyes lit up with excitement.

"yes. Solar cell. What's wrong? ”

"Great! Take me to meet your friend Whiskers. ”

The girl in white said: "Weiwei is not a friend, it is an off-road vehicle. ”

"Whatever it is. Take me there. Uncle Bearded rubbed his hands excitedly, and then walked out of the room with a cigarette.

The girl in white also followed.

Marven and Mia had no choice but to follow slowly. Marven told his sister as he walked in front: "Mia, don't look down when you walk." Just look at me. ”

Mia nodded, shuddering, tugging at Marven's clothes.
