We decided to slightly change the concept of our illustrations in the Mostriki app. Kids love movement! And we decided to revive them all. Now in our application there are 18 animated colorful illustrations for each chapter. Soon. Already here.

Rainbow is visible only to man. Animals do not distinguish its spectrum. 🙈

In nature, a rainbow appears when the rays are refracted in water droplets. The rainbow can be both solar and lunar.

✔️ Each droplet works like a prism and spreads the white color of the rays into a multi-colored beam.

✔️ The colored rays exit the prism at different angles.

✔️ Color depends on the length of the light wave. Red has the longest wave, while violet has the shortest wave.

On earth, we see only a part of the rainbow in the form of an arc, but from a plane the rainbow will look like a circle. Approaching the rainbow is impossible, because the horizon is shifting all the time. In his youth, Pharaoh tried to reach the rainbow, but he never succeeded. Now he just admires it. 👀

The solar system rushes through space to the center of the galaxy at a speed of about 200 km / s. We are heading towards the constellation Cygnus, but we are unlikely to reach it. The whole universe does not stand still.

Earth and other planets travel in space in a spiral, because they rotate around the sun. And it flies in a straight line.

Love science puzzles? 💡

Arsians Boods also loves them! This Monday, he thought about the optical illusion, and found the answer only on Friday. 😳🤔

👀 Carefully look at the photo number 2. What do you see? Horizontal lines in the center of the picture slightly deviate?

In fact, they are parallel. But we are deceived by the background of lines that converge at one point. They create the illusion of movement.

Why?

💡In the meantime, when the eyes see the image and when the brain processes the information, there is a delay of a few milliseconds.

💡In the process of evolution, the brain has learned to compensate for this delay.

💡When processing signals from the visual organs, he tries to predict how the picture will look in these fractions of seconds.

Thanks to this ability, we can catch the ball on the fly and calmly walk the streets without bumping into other people. 🤗

The surface of Mars is heavily scratched by the Mariner Valley near the equator. The depth of the depressions reaches in some places up to 11 km, and in length they extend to 4,500 km. A sightseeing tour around it would take 2 weeks if traveling by car. 🚖

The entire valley of Mariner is assembled from a multitude of canyons that are intertwined in mysterious mazes in places. The layered structure of earth like rocks on the sides of the canyons indicates the possibility of the existence of a vast ocean on Mars in the past. On Earth, sedimentary rocks at the bottom of large reservoirs accumulate in the similar layers.

Huge ice clouds 40-50 km high accumulate above the valley. The Martian wind stretches them hundreds of thousands of kilometers across the planet. In the morning, a fog consisting of ice crystals rises above the labyrinths. From a distance it seems that the valley is shrouded in a continuous veil, but near the cloud they differ in shape and cast shadows on the surface. Perhaps these shadows form strange signs that earthlings observe with surprise. 😳

When a lightning with a large charge falls into the sand, the sand around the lightning strike fuses together, and fulgurite is formed.

Why?

⚡Electrical current in a split second heats the water vapour and air.

⚡ Due to the pressure, the air expands and explodes sand grains.

⚡ Inside the molten sand, a cavity is formed due to air.

⚡After a lightning strike, this sand is rapidly cooled and a glass tube is created.

Sand tubules are called fulgurites. Sand figures similar to them are obtained after a nuclear explosion. Imagine the power of lightning? 😳

Have you seen fulgurites? They are beautiful, right? ☺️

Aphrodite often watches over Mercury.

It has the highest temperature drops among the planets of the solar system. In the daytime + 430 ° C, and at night -180 ° C. More than 600 ° C difference, can you imagine? 😳 No fur coat will save from such fluctuations!

However, on Venus, the climate is even hotter. The temperature can get to the mark of + 500 ° C, because the atmosphere of the planet contributes to extreme heat. And Mercury has almost no atmosphere.
