In the central square of Rainbow Town, a magical castle wrapped in vines is shining with emerald light. This amusement facility called "Green Jump Fort" is not only a happy haven for children, but also a breathing ecological miracle-it uses recycled plastic to build a skeleton, uses solar panels to weave a dome, and even the surface of the trampoline. Elastic materials are all derived from fishing nets recycled from the sea.
"Are you ready? "Aunt Lin, the director of the garden wearing overalls, pressed the start button, and the LED screen on the outer wall of the castle immediately lit up the forest projection. The moment the ten-year-old Duo stepped on the trampoline, the pressure sensor under her feet began to work. Every time she jumped, the electronic bud on the wall bloomed, releasing stored fresh negative ions. "This is converting exercise energy into air vitamins! "Aunt Lin explained with a smile. When thirty children jumped at the same time, the windmills on the top of the castle rotated rapidly, delivering green electricity to the street lights throughout the square.
The birth of this environmentally friendly bounce fort originated from an accident. Three years ago, the architect's father took seven-year-old Xiaoman to visit the landfill. The child stared at the mountains of plastic toys and asked,"Can these become an amusement park? "This question ignites the creativity of interdisciplinary teams. They used 3D printing technology to reshape recycled plastic into a honeycomb structure, which not only ensures load bearing but reduces material use; moss culture medium is implanted in the interlayer of the trampoline to allow each bounce to drive air circulation and help plants absorb carbon dioxide; even the safety fence The fibers come from recycled old sweaters.
"Look at my air cannon! "Five-year-old Ajie pressed down on the trampoline hard, and the air pump hidden in the spring immediately worked, spraying fresh air with the smell of rosin into the air through the hose. This is a "happy purification system" specially designed by the team-when children jump to their heart's content, the device will automatically filter PM2.5 in the air. The electronic screen in the corner of the square displays data in real time: 386 cubic meters of air have been purified today, equivalent to the workload of 20 adult sycamore trees.
In the parent-child workshop on the weekend, children are making "seed trampoline stickers." They used degradable glue to stick wildflower seeds to the edge of the trampoline. As the sun and rain, these seeds would fall into the soil with the slight vibrations of the trampoline. "When spring comes, a sea of dandelions will bloom here! "Duoduo carefully fixed the last seed. She wore a hairpin woven from used trampoline rope in her hairroom, a prize from last week's environmental creativity competition.
This magical castle is changing the entire community. Retired teacher Grandpa Chen brings his grandson to exercise every day. He said: "Dancing here for ten minutes is more refreshing than dancing in the square! "Convenience store owners replaced plastic packaging with degradable materials just to get 'green points' for entering the bounce fort. Even the stray cats in the town have found new jobs-they nest in ecological nests at the bottom of the castle and become natural "pest controllers."
The most touching changes have occurred in children. Xiaohu, who once competed for toys, now carefully checks whether the screws of each trampoline are loose; Lele, who always loves to throw snack bags, has become the "little guard of garbage sorting"; and Duoduo wrote in her composition: "When we jump, Mother Earth is also breathing gently. "
As dusk falls, the solar lights in the Bouncing Fort turn on one after another, dyeing the entire square a warm amber color. The laughter of the children and the turning sound of the windmill intertwined into a tune, and the surface of the trampoline fluctuates slightly, as if the earth was swaying gently to the rhythm. This hall of joy built with waste is telling the world in the most dynamic way: environmental protection is not a heavy responsibility, but a beautiful mission that can be completed with leaps and bounds.
When the last batch of children reluctantly left, Aunt Lin turned off the main switch. But the bounce fort is still quietly working-the roof, which has collected the day's sunshine, begins to release heat into the underground reservoir in preparation for tomorrow's irrigation. Under the moonlight, the electronic fireflies on the vine walls are flickering and dimming, as if telling an eternal truth: When we treat nature gently, the whole world will become a playground full of surprises.
