A scientific experiment? There are no instruments or bottles on this table. How could it be a scientific experiment?

Three-year-old Mia doesn't quite understand what the science experiment is, but five-year-old Marvin does.

Marvin raised his question. The bearded uncle explained for a long time but Marvin still didn't understand. But he understood one thing.

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 entire city.

This experiment was successful, but it encountered a problem: there is no problem in transmitting something as light as a hair or as small as a hair, but it will fail to transmit something larger than a hair and heavier than a hair.

This is why the girl in white and the bearded uncle are interested in Marvin and his friends.

Although Marvin told Uncle Bearded that they used Grandpa's old cane to travel among the stars, Uncle Bearded said that interstellar travel was not a problem, the problem was how to travel inside the bubble. So Marvin and Grandpa's old cane

It doesn't solve the problem that the bearded uncle encountered.

"Then how can we solve the problem?" Marvin asked.

"I do know the solution to the problem, but I don't know how to do it. I need to generate huge electric energy instantly. The stronger the electric energy, the stronger the transmission ability."

Marvin thought for a moment and said, "Wouldn't it be possible to use the electricity in this city?"

"It's OK. But the electric energy needs to be collected and discharged at once."

Marvin didn't understand what it meant at all. However, he knew that there are many energies on the earth that are stronger than electricity. Earthquakes, hurricanes, and tsunamis are energies on the ground. And the stronger energy is in the sky, and that is solar energy.

It is said that the total energy on the entire earth is less than one billionth of the solar energy.

Marvin pointed to the sun in the sky and said, "Can we use solar energy?"

The bearded uncle glanced at the sun and said: "I understand what you mean. Solar energy can be used on other planets, but not on our bubble planet. Because we are now under the sea surface, the sun's rays cannot come in. This bubble

The sun in the bubble is artificial, it's actually just a big light bulb."

"Ouch! Oops!" Marvin yelled.

"What's the matter?"

Marvin said: "If that is not the sun, then the night we encounter is not a real night. If there is no night, then Grandpa Cane will not be able to restore energy, and it will not be able to take us to travel among the stars."

"Really."

"Also, the solar panels on the off-road vehicle cannot be charged. I have to go down quickly and tell Weiwei to stop him from running around, lest he drains all the power in the battery."

"Battery? What did you just say? You said battery?" The bearded uncle's eyes shone with excitement.

"Yeah. Solar cells. What's wrong?"

"Great! Take me to meet your friend Weiwei."

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

"No matter what it is, take me there quickly." The bearded uncle rubbed his hands very excitedly, and then quickly left the room.

The girl in white also followed out.

Marvin and Mia had no choice but to follow slowly. Marvin told his sister while walking in front: "Mia, don't look down when you walk. Just look at me."
