When the students present heard that the hamster was going to be rescued, their eyes widened in unison, their hearts became excited to varying degrees, and they listened carefully.
Taking advantage of this rare opportunity, Zhang Zian first explained the principle to them.
Hibernation is an instinct shared by many animals, ranging from small rodents, medium-sized reptiles, and even large carnivores such as bears. In order to cope with the cold and food shortages, they all choose to hibernate to fight against the harsh environment. When these animals hibernate, their body temperature drops, their metabolism decreases, and they can even stop eating, drinking, and moving throughout the winter.
Hamsters also have a certain degree of hibernation ability, but compared with those well-known hibernating animals, hamster's hibernation ability can barely be regarded as entry-level.
Other hibernating animals will make professional preparations before entering hibernation, eat themselves fat, store enough fat in their bodies for consumption and keep warm, choose a shelter from the wind, comfortable, secluded, and safe, and hide themselves in Inside, when I got out again, it was already spring and flowers were blooming.
Shishi likes to wear sweaters for her and Liu Sanlang's Labrador to keep warm. Zhang Zian specially told her about the "specific surface area" for this purpose. The smaller the animal, the larger the specific surface area, the easier it is to lose temperature. Large dogs do not need winter clothing, only small dogs do, depending on the situation. Hamsters are much smaller than small dogs and are more sensitive to temperature changes.
The hibernation of hamsters is very hasty. They don't know how to plan ahead, and they will temporarily enter the hibernation state when they encounter harsh environments that cannot survive. This kind of hibernation is very dangerous, and they may not wake up. Everyone can't stand it, and feel that calling this life-saving behavior of hamsters "hibernation" is really sorry for other animals, so they simply call hamsters' hibernation "pseudo-hibernation" or "false hibernation".
Although Zhang Zian has only been here for a few minutes, he has already found several problems with the details, such as not using pure wood chips, the shelf for placing the utensils is located in the north instead of the south, the indoor humidity is slightly high, the utensils are not up to standard, etc. The reason why hamsters go into hibernation, but the most essential reason is that the temperature is too low.
"In a while, I'll help everyone move the shelf under the south window. The reasons for false hibernation are low temperature and short sunshine hours. Now prepare some things separately, and let's revive them first," Zhang Zian thought. After thinking about it, he assigned the task and said, "Is there a kettle? The one that can boil water. Also, is there a syringe? Or something similar."
"There is a kettle in the classroom, I'll get it." A little boy volunteered.
Wang Yaning frowned and said, "It seems that there are syringes in the biology classroom and the school hospital... But the biology classroom and the school hospital are closed now... The biology teacher and the school doctor are not here. Why don't you buy them outside?"
"Let me go, I know there is a canteen nearby that sells toy syringes." Another little boy raised his hand and said. After Zhang Zian agreed, he rashly ran a few steps outside, then ran back and asked, "How many should I buy?"
"One, the cheapest one will do." Zhang Zian raised a finger.
"Okay." The little boy also ran out.
"Is anyone bringing candy?" Zhang Zian asked.
"I...I brought sugar..." Xiao Celery and another girl besides Wang Yaning said weakly.
"I need to add some sugar to the hamster in a while, so can you contribute your sugar? Just one piece, no, half a piece, or a small amount." Zhang Zian asked gently.
"Okay... okay." The little girl grabbed a few pieces of candy from her pocket and put them on the table.
Zhang Zian nodded to her, and then said to everyone: "Now everyone stretch out your hands and rub your hands like this to warm up your palms."
He quickly rubbed his palms together to demonstrate to everyone.
They also imitated his appearance, rubbed a few times, and the palms became red and hot.
"Okay, now each of you holds a hamster in the palm of your hand, and when you feel the temperature has dropped, rub your hands again, and breathe." Zhang Zian said, first took a hamster from the container, and warmed it up.
The three little girls each chose a hamster, held it in their warm hands, put it near their mouths, and blew hot air on them.
This is the easiest and safest way to heat up the hamster. It is not easy to control the temperature with external objects such as hot water or electric blankets, and it may be self-defeating.
But Zhang Zian only knew about this method, he had never tried it himself, and he had no idea whether it would work or not.
The heat is continuously transmitted into the hamster's body from the palm of the hand, and the hot air exhaled from the mouth blows over their heads like warm wind.
"I'm back!" The little boy who went to the classroom to get the electric kettle came back first, holding a silver stainless steel kettle high in his hand, "Is this okay?"
"Yes, yes..." Zhang Zian stared at the kettle with black lines on his face, "but the problem is... is this an electric kettle? Where is the base for electricity? Are you planning to drill wood to make fire to boil water?"
The girls also discovered this situation and were amused to giggle.
The little boy was stunned for a moment, then looked at the water bottle in his hand, he was embarrassed and stammered, "I... I'll get it again..."
"Wait a minute!" Zhang Zian called to stop him, "Put the pot down and go get the base."
"Oh." The little boy was so ashamed, he put down the pot and ran out quickly, even faster than before.
After a while, the little boy who bought the syringe came first and bought back the toy syringe. Zhang Zian also assigned a hamster to him, and asked him to follow their example and warm up the hamster.
After a few more minutes, the little boy in front finally brought the supporting base of the electric kettle with a flushed face.
"Now take half a pot of water and bring it to a boil, be careful not to burn it." Zhang Zian assigned him a task.
Half a pot of water boils in just a few minutes.
Zhang Zian handed the hamster in his hand to the little boy. He filled a small cup with half a cup of hot water, took a very small piece from the candy and put it into the hot water. The little sugar cubes melted away quickly.
He shook half a cup of hot sugar water well, and when the water cooled down to a suitable temperature, which was probably slightly higher than human body temperature, he used a toy syringe to fill up a syringe with water, then opened the hamster's mouth in the little boy's hand, and put it in It injects some warm sugar water in its mouth.
After feeding the sugar water to this hamster, he followed the same pattern and fed warm sugar water to the other hamsters held in his hands.
He put down the syringe and did everything he could. All he had to do was wait patiently, hoping that the hamsters' will to survive was strong enough.
Little Celery stared anxiously at the silver fox hamster in her hand. If her gaze had warmth, it would surely melt the ice.
Suddenly, her palms itch, as if she was scratched by something.
The hamster squirmed a few times and opened its eyes.
