"A new method?"
Wang Bo and others who were preparing to actually carry out the operation heard Wang Shanhai say this, and they all turned their heads to look at him:
"Brother Wang, is there any other way to make fire by rubbing two sticks together?"
“Of course…” Wang Shanhai nodded confidently: “We are the most intelligent creatures, at the top of the food chain who are good at using tools.”
"Why bother with your hands when you can use tools to make fire?"
As he spoke, Wang Shanhai took out a disc-shaped stone from his lower back, with an obvious hole in the middle.
This is the prop that Ren Yan found when he was explaining this method to Wang Shanhai just now.
Now it has been taken over by Wang Shanhai under the name of demonstrating to the children.
He still remembered how hard it was for Ren Yan to dig a hole in the stone, and he didn't want to show off his efforts in front of Wang Bo.
It’s better to do it in a relaxed manner, which can better show your style.
"Brother Wang, what's the use of this...?" asked a boy next to Wang Bo, and the others also looked at the stone and fell into deep thought.
"You know about steam engines, right? (...This sentence is correct!)" 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, there was a flywheel that served as the power system during the loop, relying on the inertia generated by the flywheel."
Wang Shanhai recalled Ren Yan’s words and explained slowly.
"The function of this disc stone in my hand is actually similar to the flywheel on a steam engine, and it also plays a role of inertia."
"But if we want it to work, we need to do another step."
As Wang Shanhai spoke, he completely stuck the disc of stone on the branch, completing 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 sundries that Ren Yan brought.
The middle part was inserted into the cross of the branch and tied with another small section of thin wire. Then the nylon wires at both ends were wrapped around the branch in a snake shape.
After a moment, a strange combination of branches with a stone disc at the bottom and nylon rope spirally wrapped around the top appeared in front of Wang Bo and others.
"Is this the tool you were talking about?" Wang Bo asked in confusion.
"Yes." Wang Shanhai nodded and looked at his son deeply.
He had never seen such a curious look on his son's face before, but now...
He could feel that Wang Bo had undergone obvious changes.
"I call this set of equipment a fire-making flywheel. If I add some suitable wooden boards with fire grooves, it will be a set of tools for making fire by drilling wood." Wang Shanhai said.
"How do you use this thing, Brother Wang?"
"Simple~" Wang Shanhai waved his hand slightly, took the flywheel and placed it on the wooden board where the fire groove had been opened.
After fixing the position, Wang Shanhai calmly pulled the two ends of the nylon rope wrapped around the branch.
The next moment.
The originally quiet branches began to spin rapidly, and after one rotation they immediately returned to their original shape.
The two nylon ropes that had been pulled straight returned to the entangled state due to inertia.
Afterwards, Wang Shanhai pulled again, and the branch began to spin rapidly again.
As Wang Shanhai repeated this process over and over again, smoke began to rise after more than ten seconds.
Wang Haisheng followed the previous method and quickly ignited another fire.
Look at the newly ignited flame in front of you.
Wang Bo and others looked at each other in shock.
The flame that they had previously spent a lot of energy on but had failed to deal with was now easily created into two balls by the other party.
And the last group is so freehand? !
This made them feel a little ashamed for a moment.
We are all human beings, so why are there such big differences between us?
However, despite feeling ashamed, Wang Bo and others still developed an extremely strong interest in this tool.
Who would still use a lighter when you have this thing in the wilderness in the future?
A lighter may break down 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, is the principle of this thing simply based on inertia?" Wang Bo and others seemed extremely excited at this moment.
Wang Shanhai scratched his neck slightly embarrassedly. He just let Yan talk about the principle of this thing, and he roughly knew what it was.
But if he were to really explain it in detail, it would be a bit difficult for him.
"Well, it's mainly inertia, but centrifugal force also plays a role."
"But if you want to understand this, you have to study physics well."
"Otherwise, even if I tell you more, you won't understand."
In the end, Wang Shanhai could only choose such a universal answer.
"You won't understand even if I tell you!"
This trick was a one-sentence tactic often used by his teachers when he was in school.
When facing students, he can be said to be impeccable.
"Oh, so that's it..." Wang Bo and others nodded in cooperation and took note of the physics at the same time.
It was also the first time that the seeds of physics were planted in their hearts.
Then they had a lot of fun playing with the flywheel fire-making tool made by Wang Shanhai.
At the same time, I am also thinking about continuing to imitate some.
However, he ran into a little embarrassment when drilling a hole in the stone.
