Chapter 502 It's Smoke~
"Convex lens?" The children looked at Xiao Yu incomprehensibly.
Xiao Yu smiled, "Touch and feel with your hands, the bulge in the middle is just a bulge." She stretched out her fist and let everyone look at her hand, pointing to the bump on the fist, "Look, This one is convex, and this one is concave.”
Xiao Yu also carefully wrote these two characters on the ground with a branch, "Look, isn't it easy to remember? Because it's very vivid!"
"There is a convex lens, so is there a concave lens?" Xiaoguai tilted her head, leaning on Di Jia and asked softly. Martha leaned on her brother's body like a dog, and nodded with Xiaoguai's frequency.
"Of course." Xiao Yu was stunned suddenly, convex lens...concave lens...she...she can make a telescope!
Xiao Yu reached out and pulled Xiao Guai into her arms, hugged him tightly, and then gave a hard "chirp" on his chubby cheek.
The little girl laughed loudly, then hugged Xiao Yu's neck, and continued to "tweet and tweet" several times on her face before giving up.
"Am I very smart?" Xiaoguai beamed with joy.
"Yes! About the concave lens, we will talk about it in the future. Today, I will take you to do the convex lens experiment. This will be very useful for your outdoor life in the future! Watch it!" Xiao Yu looked up at the direction of the sun, and then she She said to the children beside her, "Go and help me find a cool stone, it doesn't need to be too big, so I can..." She compared it with her hands.
The children rushed out to find the stones.
Xiaoguai rubbed her chubby face against Xiao Yu's cheek, "Mom~ Did you think of something again~"
"Well, I want to make a telescope."
Xiaoguai's mouth became O-shaped, "But..." His eyes looked around, as if he was a thief, and then he leaned into Xiao Yu's ear and said: "But didn't Grandma say that that is not It belongs to the World of Warcraft, can't you bring it out~" He frowned, feeling that his mother's memory has deteriorated~ I should eat more eggs~
"Yes, I didn't want to take it out at the beginning, because I considered that the mirror body of the telescope could not be made on the World of Warcraft, so... But you reminded me just now, if I can make concave and convex lenses, I can use bamboo to make them. For the mirror body of the telescope, after all, what we want to use is its telescopic function, isn’t it?”
Xiaoguai excitedly stretched out his little hand to grab Xiao Yu's hand, "Ah, tell me to do it~" His chubby body writhed in Xiao Yu's arms, "Okay! Like a fat caterpillar~"
"I want to eat caterpillars at night, so I need to bring jam~" Xiaoguai threw herself into Xiao Yu's arms and acted like a baby.
"How about eating tomorrow morning? The bread can only be baked after returning there~" Xiao Yu whispered in his ear like a little boy.
"Hush—" Xiao Guai blinked suddenly, "Everyone is back~"
Almost none of the children came back with two stones. Xiao Yu picked two and put them on the ground, and then stood the crystal she had ground in advance among the stones. She asked Xiao Guai to bring hay and put them behind the crystals.
She looked up at the direction of the sun, and then found an angle that could be directly irradiated by the sun, allowing the sunlight to pass directly through the center of the crystal and shine on the dry grass behind.
This time is already close to noon, but now that the sun is just right, suddenly, Xiaoguai stretched out her little finger and pointed to the hay that Xiao Yu had just placed, "It's smoking~"
