Leisurely Farmhouse in Another World

"Master, is there more, is there more?"

The girls who played together today collected their treasures one by one, and everyone had one.

In fact, they understand that on the one hand, on the other hand, they want gifts, things that they want to cherish this day forever.

They have the same idea as Mr. Ogawa.

I want to keep this beautiful and happy moment forever in my mind.

The difference is that Mr. Ogawa has the ability to turn these beautiful memories into pictures, photos, and videos to preserve them.

It just takes time.

And girls place their trust in objects, such as yo-yos. In their opinion, each sister only has one in this life.

And, it’s limited to sisters participating in the game today.

Then, these gifts are the most precious.

Used to record all the wonderful things today.

But the more beautiful and happy memories I have with you, the better.

They are greedy and want more.

"Yes, do you still want to play?"

“Want to play!!!”

With a whoosh, the yo-yo returned to his hand.

Master Xiaochuan smiled and said, "Okay, I'll play with you until you've had enough, and let's continue making other toys to play with."

PS:

Please give me more flowers, tickets, and more data, I beg you.

261 It looks so pretty when you smile, Boomerang GOGOGO! (please order)

Sometimes, the simplest materials can bring the greatest and most original pleasure.

The bamboo dragonfly master only needs a few wood chips to make.

Yo-yos only require a little magic, a string, glass and wood.

Speaking of which, girls in yo-yos and swimsuits are a perfect match.

On one side, there are rough waves, and on the other side, the yo-yo is jumping up and down︿(￣︶￣)︿

So cool, so sparkly, so charming.

Mr. Ogawa was dazzled by the dance. Yo-yo, you are a good ball ヽ(￣▽￣)?

No one should try to stop Mr. Ogawa from developing the yo-yo business. That would be my sworn enemy.

Now, Mr. Ogawa has made simpler toys.

Just a piece of wood, and it takes less than a minute to carve, and there’s no need to paint it.

A magical toy is born again.

Mr. Ogawa took it and admired it, it was a good thing.

The gift of the God of Craftsman made him unique in the field of carving, and he quickly completed the toy.

"Master, what is this? Is a piece of wood also a toy?"

"Of course!"

Mr. Ogawa took the wood in his hand and showed it to the girls in a showy manner.

"This is called a boomerang!"

Mr. Ogawa popularized the knowledge about boomerang.

Boomerang, also known as boomerang, homing device, boomerang and other names.

It can fly out and come back later.

The shapes include "V" shape, banana shape, bell shape, three-leaf shape, "ten" shape, multi-leaf shape, and various other shapes.

Many people have seen on TV that acrobat performers fly out the boomerang, circle around the audience's heads, and then fly back to the performer's hands amidst the exclamation, which is full of applause.

The "V"-shaped and banana-shaped boomerangs were once the traditional hunting tools of the Australian Aboriginals.

After a skilled hunter sends a boomerang at his prey, if he misses the target, the boomerang will miraculously return to the hand of the sender.

However, there are not as many ways to play with a boomerang as there are with a yo-yo.

Yo-yo later even had a world championship, while boomerang was much simpler.

"Master, how do you play this?"

Tia asked excitedly. She was equally happy today.

"Look!"

Mr. Ogawa adjusted his angle.

With a whoosh, the boomerang was thrown directly.

After the boomerang spun in an arc in the air, a moment later, it flew back with a swipe.

It fell firmly into the hands of Mr. Ogawa.

The girls' eyes suddenly widened.

Amazing!

Mr. Ogawa pinched the waist.

"How about it, have fun!"

"Master, please give me a try!"

Gu Leya snatched it directly and threw it out impatiently...

The next moment I was dumbfounded.

Because of the boomerang, it didn’t come back.

"Ah, this-_-||..."

Gu Leiya was stunned for a moment, then ran over and picked it up.

I lost it several times in a row, but still couldn't figure it out.

"master……"

Gu Leya got a little angry: "Why can't mine come back? Can't I just throw it out?"

"Skillful."

Mr. Ogawa held the boomerang in his hand.

Boomerang utilizes aerodynamics and rigid body dynamics.

The cross-section of the boomerang wings causes the air lift force on the boomerang to rise in the upward direction, making the boomerang body stable.

A boomerang, like a top, rotates on its axis in a straight line.

The lift and stability make the boomerang rise, and the rotation of the spindle makes the boomerang fly back.

Regarding the flying phenomenon of boomerang, it can be explained by the interaction between boomerang and air.

If there is a lack of air in a vacuum, the boomerang's flight trajectory should be just a parabola.

Once air is taken into account, the situation becomes more complicated, but we can still understand it in a relatively simple way.

Generally speaking, the flight phenomenon of boomerang is related to physical principles such as torque, angular momentum, rotational inertia, Bernoulli's principle, and centripetal force.

Mr. Ogawa explained the principle of boomerang to the girls.

"But we don't need to master too much professional knowledge. On the contrary, to play boomerang, we only need to practice. If you practice more, you can get better at it."

"Master, I want to try it too!"

Phoenix loved it.

Just take it and take a deep breath. (ceae)

Throw it out with a whoosh.

As expected of Phoenix.

The next moment, the boomerang flew into her hand.

"Yeah, not bad, it feels like flying in a circle."

Gu Leiya pouted: "Master, is this boomerang aimed at me!"

Mr. Ogawa was amused: "Just practice and you'll be fine."

"Didn't Miss Phoenix say that it's not impossible if you understand it as circling flight? It's the feeling of flying in the sky, suddenly changing your route, and circling back. Try it again?"

Gulea thought for a while.

Then, after playing it several times in a row, I suddenly felt happy.

It does feel that way, very good.

"Master, I want to play too, make one for me."

"Okay, okay, stop shaking. If you shake me again, your master will be knocked unconscious by you."

One by one they act coquettishly and cutely, and the large ones jump up and down, which is dazzling.

"One person per person, don't rush, don't be crowded..."

These girls...

Mr. Ogawa is extremely happy, please be happy slowly.

Everyone came closer to him, wishing they could melt into their bones.
