Text "Inflatable Raincoat" for the second grade of primary school

Inflatable raincoat

When school was over in the afternoon, it started raining heavily with the sound of spring thunder. Xiao Lin, a fourth grader, walked home with his classmates in the heavy rain. Xiao Lin's raincoat just passed his knees. The rainwater flowed along the hem of the raincoat and onto his trouser legs. It was blown by the wind and became extremely cold.

At night, Xiao Lin was lying on the bed and thinking: I have to change my raincoat so that it can no longer flow to my trouser legs.

How can we solve this problem? Xiao Lin has been thinking and thinking.

On June 1st, at the Children’s Day party, female classmates performed dances. Along with the beautiful music, the little actors spun and their colorful skirts slowly opened, like flower umbrellas. In Xiao Lin's eyes, the "flower umbrella" gradually blurred and turned into raincoats with open hems. That night, he bent a large circle with thick wire and sewed it on the lower edge of the raincoat, and the new raincoat was made. Before he could be happy, the question came again: How to fold such a raincoat?

It was summer vacation. Xiao Lin went swimming with his classmates. After changing into swimming trunks, he took out a plastic lifebuoy and started to blow air. The stacked lifebuoy gradually turned into a circular plastic air bag. Xiao Lin's eyes lit up and he thought: If we use inflatable plastic rings instead of iron wire rings, wouldn't it be possible to fold them up? He was not in the mood to swim, so he changed his clothes and ran home. After returning home, Xiao Lin cut off the valve of the lifebuoy, bought a plastic mold, and asked his uncle at the plastic processing shop to help him press it into an air bag. When the air bag blows up, it is similar to an inflated bicycle inner tube. Dad helped Xiaolin stick the airbag inside the hem of the raincoat. The inflatable raincoat is ready. Inflate it and wear it, hey! Not to mention how great it is!

At the children's products exhibition, the inflatable raincoat invented by Xiaolin was praised by everyone. "Inflatable Raincoat" teaching design
