"Mom! The dolphins are coming! ”

Qiao Bao pointed at the dolphin excitedly, and Qiao's mother hurriedly grabbed Qiao Bao's hand back, "Dangerous Qiao Bao, although the dolphin is a good friend of humans, Qiao Bao's hands and hands are too fragile and can be easily injured." ”

"Got it, Mom."

Qiao Bao withdrew his hand, saw the dolphin flying out of the water, screamed a few times, turned around, and plunged into the water again.

"That's great!"

Qiao Bao and Qiao's mother clapped and cheered, and the skilled Qiao's father immediately opened the large dining cloth he was carrying.

Hula-

The dolphin burrowed into the water, and the huge splash of water splashed up, even though it was covered by Joe's father's napkin, but the splash still wet the legs of the three of them.

"Wow! It's so cold! It's salty! ”

Qiao Bao immediately smelled the saltiness on his calves, "Why is this water so salty?" How much salt do you need to add? ”

Qiao Bao's words made the people around laugh, and the breeder saw that their legs were wet, and hurriedly ran over to apologize: "I'm really sorry, I didn't find it or splashed all of you, please come with me to dry your pants!" ”

"Okay, thank you."

Dad Qiao thanked him, and the three of them followed the keeper to their lounge, "There's a hair dryer here, you can dry your pants in it and then come out." ”

The breeder left to continue to perform for everyone, and Qiao's father asked Qiao Bao to take off his pants and dry them with an electric wind.

"Dad, you haven't said yet, why is this water so salty?"

Qiao Bao shook his legs and sat next to him, holding the water glass.

"The water on Mercury is not salty, just like the water in my glass."

Qiao's father blew his pants for Qiao Bao and said, "The water in the ocean is salty, because the sea contains salt."

Some salt comes from volcanoes at the bottom of the sea, and some from rocks in the earth's crust. The rocks are weathered and disintegrate, releasing salts, which are then carried to the sea by the river.

After the seawater vaporizes, it condenses into water, and the salt stays and gradually accumulates, and the seawater becomes as salty as it is now. ”

"Oh-"

Qiao grunted and drank water, Qiao's mother blinked her eyes and said with a smile: "But Qiao Bao, there is no water on Mercury, you can go up and take a look when the time comes." ”

Qiao Bao nodded thoughtfully, not fully understanding.

"Alright, the pants are blown, let's go out and continue to watch the show."

Dad Joe said, "You can't sit in the front row now, because it's going to be splashed, so the front row is so empty." ”

"Then let's sit in the back row."

Qiao Bao nodded sensibly, yes! Who wants to come out and play and get wet all over?

After watching the performance, Qiao Bao was still immersed in the cute dolphins, and unconsciously followed Qiao's mother and Qiao's father to a strange place.

"Hey, where is this? Isn't it an aquarium? ”

Qiao Bao looked around curiously, in the dark starry sky, there was a little bit of starlight.

"I'm curious, but there's still a place like this in the aquarium."

Qiao's mother looked left and right, "Like, planetarium?" Why is there a planetarium in an aquarium? ”

"No, I look more like a rocket launch pad."

Papa Joe saw a launch pad, "Look! I said it's a cosmodrome, right? ”

"It's really like it!"

Qiao's mother also saw those models, and squatted down to look, "Qiao Bao, come and see, this is a spaceship!" Don't you want to go to the universe? I'm going to take this manned spacecraft! ”

"Wow... That's what it looks like! But this one is too small for me to sit in..."

Qiao Bao looked at the spaceship, his eyes full of stars.
