The Idol Group Pet Became a Final Boss!

"Try it, try it." Zhou Yan grinned, "You'll know how difficult it is after you try it! I have been practicing for a long time before I can float for six consecutive times!"

The girl lowered her head and picked up a stone casually.

Zhou Yan immediately said: "No, no, you can't pick a rock well. You have to choose a flat or a dish!"

"It's okay, I'll practice."

"Yimei, everything is rigorous!" Zhou Yan has a strong sense of variety, and he just pulled the stone from Xiangyi's hand, led her to choose carefully, and commented on the stones one by one, "Too big, no good; too fat," It's not good; it's too ugly, let alone."

Variety effects came out all at once.

——[Yanbaoyan dog has hammered! 】

——[Yan Sansui took Yimei to find a stone, too cute! 】

——【I laughed until the spiral ascends to heaven, Yimei is too difficult! I feel like bringing a cub every day, little baby Yuyu, little brother Lanlan, now there is a giant baby Yanbao! 】

…

Finally, Zhou Yan chose the right stone, and he came to Duan Kepu in no uncertain terms:

"Yimei, do you know why the rocks bounce when the water floats? It's actually very simple. The higher the flow rate, the lower the pressure.

The density of stone is greater than that of water. When the water is floated, the water will flow quickly in a short time, so the water surface will put pressure on the stone.

When the pressure is greater than the gravity of the rock, the rock will bounce. The more times this situation is repeated, the more times the rock will jump on the water surface. "

Appropriately agree: "Well, principles of fluid mechanics."

Zhou Yan gave a thumbs up: "Smart."

The audience in the live broadcast room was almost silly.

Don't you just take a dip?

Why are you still so advanced? !

Appropriately weighed the stone in his hand. I have to say that Zhou Yan chose this piece very well and feels great.

The girl pinched the stone with her thumb and thumb, behind her index finger, and seeing her gesture, Zhou Yan said to her expert: "Hey, expert!"

Yiyi smiled calmly, slowly leaned down, her posture was elegant and casual, she seemed to use no strength, her index finger moved the stone, but the stone was spinning with extremely strong force and was thrown out by her!

"boom!"

"boom!"

"..."

After more than a dozen sounds, the stone "fluttered" and sank to the bottom!

Zhou Yan:?

Audience:?

Is it an illusion? Must be? !

Appropriate but "Well", seemingly not satisfied with the results, she took out a spare stone and threw it again!

The familiar "pop" sound once again dominated everyone!

This time, it rang twenty-three times!

Zhou Yan was dumbfounded.

Thinking of what he said just now, "Brother Scream, I will teach you", his toe was awkwardly picking the soles of his shoes, and he wanted to jump into the pond on the spot!

This fucking... this is unscientific!

The girl opened her lips lightly and her voice was soft: "There was once a professor who used the weight and speed of the stone and the influence of the air to sum up a well-known equation-the water-floating equation."

Zhou Yan was perplexed: "Huh?"

The audience was in a trance: [Yimei is fooling people, right? Right? ? 】

Just listen to the appropriate and continue: "The equation is: MxA=P–MG+air influence. M represents mass, A represents vertical acceleration, P represents water surface feedback pressure, and MG represents gravity.

This equation has played an important role in the study of the issue of ‘aircraft icing’ and has also been applied in the field of criminal investigation to calculate blood splashes. "

Zhou Yan:? ? ?

Audience:? ? ?

Excuse me, I really do.

Is this science?

Sorry, I'm not worthy anymore! !
