There is a tall locust tree at the head of Lingxin Village, and the elders tie four thick swing ropes to its sturdy branches, and the swing with heart-shaped pedals is tied to the swing, and there is a bell with a ribbon hanging on the tree branch in front of the swing, and the swing can be touched to win cheers and praise.

Swinging is a combination of high, floating, leisurely, skillful, soft, beautiful, joyful and other characteristics, here is a popular sport for children. Children often come here to play and show off their skills. Swinging is not difficult, but the difficulty is to swing to a high place to touch the bell, which is indeed a test, not every soul can do it.

This time, Greedy finally mustered up the courage and volunteered to step on the swing, "Today, I must touch that bell ten times, otherwise, I will treat you to a big meal." ”

Everyone was taken aback by his unusual behavior, thinking that he had taken the wrong medicine. You know, he has always been the most greedy for life and afraid of death, and when other souls used to play on the swing, he always didn't participate, and said, "I don't want to risk my life to do this kind of fearless adventure." But to do so today is really confusing to the rest of the spirits. I saw him stand on the swing, stretch out his hands, grasp two hemp ropes each, and then tell the ruthless heart to pull the swing back, and then let go, so that the swing moved, and then he kicked his feet, only to see the swing swing higher and higher.

But this is not as simple as greedy imagination, he gradually felt a little light-heavy, that fluttering feeling really made his heart not collapse, bang, bang, the hand holding the rope naturally grasped tighter. Seeing that the bell was in front of him, greed didn't dare to reach out to touch it, and the other spirits below were cheering for him, telling him to touch the bell, that was the best time, but when greed stretched out his hand to touch the bell, he suddenly looked at the ground, this look really scared him, and he suddenly had no bottom in his heart, like a deflated balloon, the more he swung more and more boring.

At this time, the ruthless heart at the bottom reminded: "Don't forget what you just said, we will definitely eat you hard at that time, and see what you do." ”

When I heard this, I remembered what I just said, and how helpless I felt in my heart! But he immediately mustered up his strength, kicked his feet again, and then said in a loud voice, "Let you see what I have done!" I saw that he was getting more and more energetic.

Ruthless was already impatient waiting below, and said to Ambition: "This guy is still unrepentant when he dies, and he always likes to talk big, I dare say that he will never touch that bell." ”

When this word reached the ears of Greed, perhaps stimulated, he began to try to reach out a hand to touch the bell, but it was always a little bit close, and everyone refueled him below, and Greedy did not forget to thank them, "Thank you for your support, I will definitely live up to your expectations." I just heard the bell ringing crisply, "I finally touched it." Everyone applauded him, greed was obviously a little carried away, and his hands let go of the rope and arched towards the spiritual heart below: "Thank you for the cheers." ”

Due to the excessive force just now, the inertia was too great, and the greedy foot began to detach from the pedal, which made him frightened, looking at the ground, his eyes almost didn't fall out, but fortunately he reacted in time, kicked hard, and hugged his hands on the tree, causing everyone to have a false alarm with him.

At this moment, I only heard a ruthless and smug smile: "It seems that you have ordered today's meal." Greedily looked at the bell not far away, and with an idea, he stretched out a hand to touch it, and counted proudly: "One, two, three...... look, didn't I touch the bell ten times?" ”

Ruthless shouted below: "You are out of a thousand, this doesn't count." ”

Greed argued, "We don't have a rule that you have to swing the swing and touch the bell." "I was so angry that I stomped my feet. Greed got carried away again, and took advantage of the ruthlessness to wave his hands and make a grimace, and at this moment, because his feet could not be firmly attached to the tree, he fell directly from the tree, which made everyone's stomachs hurt with laughter.

Then, everyone took turns to perform, and they all knew the skills of swinging autumn, squatting when descending, and standing up when rising. Because when you squat, you can release the stored gravitational potential energy and convert it into kinetic energy. In this way, you can float in the air effortlessly. They competed to see who could ring the bell, and whoever would hit the most would suffer the most. The ethereal figures, the jingling bells, and the thrilling swings are breathtaking.

Next to the big tree there is a seesaw, which is set up for those who dare not play on the swing. Although it is not as exciting as swinging, it is definitely no less fun than swinging. We all know that when playing seesaw, if the other person is heavier than us, we have to move back; If the other person is lighter than you, you have to move forward, otherwise there will be no fun in playing seesaw. Huixin once said a very philosophical sentence about this: Why don't we sit close to the middle when we play seesaw? The reason why we love to sit on the edge is because we believe that there must be many beautiful things that are always hidden behind the unfamiliar. It's just like our lives.

In addition, children often like to make homemade soap to blow bubbles, they pick soap horns from the soap tree on the mountain, then take out the soap beans inside, then smash the soap beans, filter them with gauze and water, and then add honey to the soapy water, so that the soap liquid is made. They then made a heart-shaped bubble blower out of a tough weed pole, so that they could blow out heart-shaped soap bubbles, and the children not only danced with joy when they saw the colorful heart-shaped soap bubbles flying in the sky, but also always enjoyed it.

Now, the children have learned from Huixin about the reason for the formation of colorful soap bubbles: the reason why soap bubbles are colorful is because when light passes through the film of the soap bubble, the top and bottom of the film are refracted, and the soap film can contain up to about 150 different layers. The messy color combinations we see are caused by unbalanced layers of film. The last film layer reflects red light, the thinnest reflects violet light, and the center reflects colorful light. Whereas, soap bubbles are formed due to the surface tension of water. This tension is the mutual traction force that exists inside the object and is perpendicular to the contact surface of two adjacent parts when it is subjected to a tensile force. The mutual attraction between water molecules on the surface of the water is stronger than the attraction between water molecules and air. These water molecules are as if they are glued together. But if the water molecules are too glued together, soap bubbles will not form easily. The soap bean liquid "breaks" the surface tension of the water, reducing it to only 1/3 of what it normally would, which is the optimal tension needed to blow bubbles.

Being able to learn the common sense of life through play, presumably this is the way that everyone likes, Huixin always guides the children to study hard, so the children respect and worship him.

However, the good times are always short-lived, and the time of childhood also slips away unconsciously, and the joy left behind can only fade into memories in the mind. Children seem to have grown up overnight, because they are immersed in a happy childhood, and they do not feel the worries and sorrows that exist in life. But, whether they want it or not, the rings of time send their life cycle into adolescence, the transition to adulthood. From then on, the rebelliousness and willfulness in their character will gradually appear.
