Chapter 84 Fire Making Set [Please read, collect, monthly pass recommended]

"New method?"

Wang Bo and others who were about to do the actual operation heard Wang Shanhai say this and turned to look at him:

"Brother Wang, is there any other way to make fire by drilling wood?"

"Of course." Wang Shanhai nodded confidently: "We are at the top of the food chain who are the most powerful among all creatures and are good at using tools."

“Things like drilling wood to make fire can be solved with tools, so why bother?”

While he was talking, Wang Shanhai took out a disc-shaped stone from his lower back, with a hole clearly punched out in the middle.

This is the prop that Ren Yan found just now when he was explaining this method to Wang Shanhai.

Now it has been borrowed by Wang Shanhai to give demonstrations to children.

He still remembered the difficulty Ren Yan had when opening the hole in the stone. He didn't want to put on a show of strength in front of Wang Bo.

It's better to do it more relaxedly to show your own style.

"Brother Wang, what's the use of this?" A boy next to Wang Bo asked, and the others also looked at the stone and fell into deep thought.

"You know steam engines, right? (This sentence is okay!)" Wang Shanhai glanced at everyone, then picked up a branch and passed it through the disc stone.

"When the steam engine first became a power source, it had a flywheel that acted as the power system during the loop. It relied on the inertia generated by the flywheel."

Wang Shanhai recalled Ren Yan's words and explained slowly.

"The function of the disc stone in my hand is actually similar to the flywheel on a steam engine. It also plays an inertial role."

"But to make it work, we need to take another step."

As Wang Shanhai spoke, he completely stuck the round stone on the branch, which was considered the first step.

Then he skillfully used a knife to cut a cross on the top of the branch, and then pulled out a nylon rope from the debris Ren Yan brought.

After stuffing the middle part into the cross of the branch and tying it with another small section of thin wire, the nylon thread thrown out from both ends was wrapped around the branch in a snake shape.

After a moment, a strange combination of tree branches with a stone disk hanging at the bottom and a nylon rope spirally wound on the top appeared in front of Wang Bo and others.

"Is this the tool you are talking about?" Wang Bo wondered.

"Yes." Wang Shanhai nodded and took a deep look at his son.

He had never seen such a curious look on his son's face in the past, but now.

He could feel that Wang Bo had changed significantly.

"I call this set of equipment a flywheel for drilling wood to make fire. If you add some suitable wooden boards with good fire slots, it will be a tool set for drilling wood to make fire." Wang Shanhai said.

"How do you use this thing, Brother Wang?"

"Simple~" Wang Shanhai waved his hand slightly, took the flywheel and propped it up on the wooden board where the fire trough had been opened.

After fixing the position, Wang Shanhai calmly pulled both ends of the nylon rope wrapped around the branch.

next moment.

The originally quiet branches began to rotate rapidly, and after one rotation, they immediately returned to their original state.

The two nylon ropes that were pulled straight returned to the entangled state again due to inertia.

After that, Wang Shanhai pulled again, and the branches began to spin rapidly again.

Under Wang Shanhai's repeated actions, more than ten seconds later, the smoke began to rise.

Wang Haisheng followed the previous method and quickly ignited another flame.

Look at the newly lit flames in front of you.

Wang Bo and others looked at each other with shock in their eyes.

They had spent a lot of energy on one flame before, but now they were able to create two flames so easily.

And the last one is so freehand?!

This made them feel a little ashamed for a while.

We are all the same people, so why are there such big differences?

However, shamefully, Wang Bo and others still became extremely interested in this tool.

In the future, if there is such a thing in the wilderness, who will use a lighter!

A lighter may break at any time, but this thing can be made in minutes.

It doesn’t hurt your hands!

It is simply a gift from nature!

"Brother Wang, does the principle of this thing rely solely on inertia?" Wang Bo and others seemed extremely excited at this moment.

Wang Shanhai scratched his neck in embarrassment. He just let Ren Yan mention the principle of this thing, and he probably knew what was going on.

But it would be really difficult for him to tell him truthfully.

"Well, it mainly relies on inertia, but there is also some centrifugal force."

"But if you want to understand this, you have to study physics."

"Otherwise, even if I tell you more, you won't understand."

In the end, Wang Shanhai could only choose such a universal answer.

'You don't understand even if I tell you!'

This trick was a one-sentence technique that was commonly used by teachers when he was in school.

When facing students, he is impeccable.

"Oh, that's right." Wang Bo and others nodded cooperatively, and at the same time wrote down the physics stuff.

Physics also planted seeds in their hearts for the first time.

Then they had a great time playing with the flywheel fire-making tool made by Wang Shanhai.

At the same time, I am also thinking of continuing to imitate some.

However, I ran into a little embarrassment when it came to making holes in the stone.

Without the right tools, it can be really difficult to drill holes in rocks.

Seeing this, Wang Shanhai smiled and remembered the solution given by Ren Yan:

"If you're not in a hurry, you can just find some clay and make a clay disk with a hole in the middle."

"After drying, it can completely function as a stone disc."

After hearing this, Wang Bo and others were stunned for a moment.

I’ll join in?! How can I still play like this?!

At this moment, they were deeply aware of their own shortcomings, and they all looked at Wang Shanhai with admiration.

Jieren is not an ordinary person!

Wang Shanhai straightened up in great relief.

Look, my own son has begun to worship me!

At the same time, in the live broadcast room.

Netizens were also extremely excited:

"Mom! I learned something again during the live broadcast!"

"This pig-headed man is still very strong. He has already mastered the method of drilling wood to make fire!"

"What a god, pig-headed man, he is Bajie, okay?!"

"No matter what, Class 9's outing has begun to show results!"

"I have learned my inertia just by watching it. This live broadcast is poisonous!"

"Sure enough, anyone who can play with Teacher Ren is not a normal person."

"Maybe birds of a feather flock together? (dog head)"

"Look, you can also learn the use of idioms in the barrage. Sure enough, they are not serious people! (Gotou)"

However, while netizens were happy.

Longtoushan Wangbochu.

Wang Shanhai, who was feeling proud, heard an unusually abrupt sentence.

"Actually, there is an easier way."
