"This is..."

"According to Dikao's description, this thing can be carried by manned space, so it should be no problem to carry a large camera." Niteya said, "As long as you fly high enough, make a camera that is large enough, and can bring the scenery closer, you should be able to take pictures of the country's map."

"But is it that easy to get close to the scene?" Alisa asked.

"Well, just make the glass convex." Nitia replied, "Just engrave the fire magic array to heat up the air, and then add the wind magic array to promote the airflow..."

"Do you need me to do?" Alisa asked.

"I asked Nathan to buy cowhides across the country," said Nitia, "I need to be a big guy."

"I understand." Alisa nodded and turned around and left.

Netiya put the drawings of Dikao back into the wooden folder and began to think alone.

If flying into the sky can detect the whole country, then in theory, can it be even possible to detect other countries as long as you fly high enough?

The naked eye may not be able to see it so clearly, so if there is a large enough magnifying glass...

Thinking of this, Nitia was suddenly stunned. Isn’t her glasses just a magnifying glass?

That's right, Nitia is not myopia, but she usually needs to see some small things when doing experiments, so she uses the eye socket of her right eye to clip a lens.

This was discovered by her accidentally when she was a child.

There are no glasses in this world. Her glasses are lenses sandwiched on the eye sockets, and there is no shelf.

However, then came up with a question: Since the convex lens can enlarge an object, can the concave lens shrink the object?

This thing is worth trying, so I immediately walked out of the laboratory and went to the factory next to me to ask Rudolph to help her make a concave lens and prepare to do an experiment.

Then he ran into the forest and found Enjieli.

"Is there anything wrong?" Enjieli, who was playing with the children in class, asked with his head up.

"I want to ask if there are any plants that can secrete a gel, preferably with a certain degree of elasticity." Niteya asked.

"Yes." Enjieli nodded, "How much is needed?"

Nitea grinned: “A lot.”

Because she thought of a problem, hot air balloons can indeed be made of cowhide splicing, but hot air balloons sewn with thread cannot contain the air, so they need to add a non-breathable thing to the hot air balloon.

So she thought of using something like rubber for tires as the internal material. If possible, it is best to apply it directly and stick it with cowhide. In this way, as long as it is not breathable, it can be used as a material to make the hot air balloon fly.

But before that, Niteya decided to do a small experiment first.
