Margarita sang her ringing, pleasant little voice:

  - What a school life ... Where is the test every day! Addition, division, multiplication table ...

  Children on scooters have already left Moscow. The majestic, beautiful city was left behind. The capital of the most powerful country in the world, it makes an indelible impression on the entire planet. But the boy with the girl does not pay attention. One thing worries them - as if, the police did not slow down, and did not demand documents from the youngsters.

  But the rules, they do not violate the movement, adjusted to automatism.

  Oleg Rybachenko expressed his opinion:

  - The multiplication table is primitive ... I personally dream to refute Einstein's theory of relativity. In particular, the possible speeds exceeding light in a vacuum. And I have a lot of interesting ideas on this topic.

  Margarita shook her head.

  - You should not express them ... Theory is boring! And practice is expensive!

  The boy just giggled in response ... And he added gas. Yes, these girls do not like boring scientific reasoning. Give them something simple. Like, for example, adventures with greentails. And the soul wants something else. Fly to cosmic worlds. See life beyond the solar system.

  For example, a mixture of the Colorado potato beetle and pineapple. Shake hands with your brother according to reason. Or maybe a shaggy wing, or nose. How interesting must these aliens be. What do they eat for breakfast? Or maybe they replenish their energy with electricity! What are they still funny creatures!

  Oleg slightly tilted the scooter and asked Margarita:

  - What do you think about life on other planets?

  The girl shot her eyes and answered fervently:

  - I do not know ... Although the existence of other worlds is not contrary to science!

  Oleg agreed and nodded:

  - It's not even Newton's biome, but the Pythagorean theorem!

  Margarita giggled and rang out in a juicy voice:

  - As well, there is no dirty theory. We will learn necessarily connected ...

  He drove lush May grove. The air is filled in late spring. And everything is so joyful in my heart, and forget-me-nots are flourishing.

  The dacha of Oleg Rybachenko"s parents is rather large and elegant. With a fence and a large plot of land. The boy opened the door with an electronic key and invited the girl into the courtyard.

  Oleg was cheerful, and he was impatient to show the discovery to his friend. A boy with a smile on his lips led the girl to the basement. He was excited about his discovery.

  Margarita lingered. She looked at the bizarre paintings in a cubist manner and asked in surprise:

  - What do you have? Scripts by Picasso?

  Oleg shook his head:

  - No, it's my dad indulging. He is not only a famous science fiction writer, but also an artist. Some of his paintings cost a lot of money they were auctioned off.

  The girl whistled:

  - A decent cottage ... Three floors, and there is a kind of underground pool.

  Oleg nodded vigorously with his bright, short-haired head:

  - The pool is so-so - a splash pool. But next to the laboratory, which made great discoveries.

  Margarita expressed quite an adult thought:

  "I"m still afraid if we"re technologically behind the West." Somehow, science fiction is not fashionable!

  Oleg confidently stated:

  - As long as there are guys like me ... That"s not what we can do! For example, I think how to make a weapon that neutralizes a nuclear explosion. Then, for example, to us, any of the missiles will not be terrible!

  The girl giggled wittily and rounded eyes:

  - Neutralization of the atomic bomb? That's cool! The boy walked back in his arms. He was as clever as a chimp. Then he got to his feet opened the doors to the basement for Margarita. They walked along the corridor, Oleg opened another armored door. The children took a few steps and ended up in the laboratory. There was a mass of various devices, sensors, flasks and test tubes. Twisted the wires ...

  And in the very center of the laboratory there was something similar to a widescreen TV, but behind it were a lot of levers and buttons. Looked fancy.

  The boy proudly put his fists on his hips and said:

  - Here it is a time machine!

  Margaret chirped in surprise:

  - And this is a time machine? So much on the TV looks like ...

  The girl went to the unit, pointed at the screen with her index finger. Carefully held on the surface and whispered:

  - Well, you and the inventor ... And how does it work?

  Oleg Rybachenko took a serious look and, turning the lever, replied:

  - It shows parallel universe. We ourselves do not move in it.
