1. First, we prepare the following materials: infusion tubes, scissors, glass balls and scissors.

2. Cut two infusion tubes with a length of 15CM, and cut them into spirals as the tail of goldfish.

3. Cut another 20 cm long plastic tube and put the cut spiral infusion tube in the middle.

4. Cut the remaining pipe from the middle and turn it into plastic skin.

5. Start knitting fish body parts.

6. Pay attention to the size of the fish, which can be adjusted by the tightness of weaving.

7. This is semi-edited. At this time, the fish head should be folded.

8. Cut another section of pipe, about 1cm long, for fish mouth and marbles for fish eyes.

9. Finally, the fish's eyes and mouth are assembled. By adjusting the elasticity and setting, the goldfish woven with plastic infusion tube was completed. Is it a cute little fish?

Infusion tube material:

The medical infusion tube is made of polyvinyl chloride, which is a plastic, the infusion bottle is made of polyethylene or polypropylene plastic, and the infusion tube is made of medical nontoxic transparent soft polyvinyl chloride plastic or high-performance polyolefin thermoplastic elastomer material.

Polyvinyl chloride (PVC) is the initiator of vinyl chloride monomer in peroxides, azo compounds and so on. Or a polymer polymerized under the action of light and heat according to a free radical polymerization mechanism.

Vinyl chloride homopolymer and vinyl chloride polymer are collectively referred to as vinyl chloride resin. When the temperature is above 100℃ or exposed to the sun for a long time, it will decompose to produce hydrogen chloride, which will further decompose automatically, causing discoloration and rapid decline in physical and mechanical properties. In practical application, stabilizers must be added to improve the stability to heat and light.
