We will encounter all kinds of rubber products in our lives: woven rubber bands, erasers, sports basketballs, footballs, sports shoes, boots, hoses, tires, bicycle tires and so on.

1. The role of rubber

Their greatest feature is flexibility. People are interested in rubber because of its elasticity. The first bicycle had wooden wheels and it was very bumpy to ride. Since the discovery of rubber, people have placed rubber on the outer edge of the wooden wheel to make bicycle riding more smoothly. Later, inflated rubber tires. We walk, we climb, we wear rubber soles. Cars overturned mountains, planes took off and landed, and rubber tires were their shoes. Seventy percent of the world's rubber is used to make tires. Interestingly, the bottom of the bridge is also lined with thick rubber support pads, which, together with the rubber products used in daily life, make full use of the elasticity of rubber.

2. The Hometown of Rubber

The hometown of rubber is in South America. There is a rubber tree growing there, and when it cuts the bark, it will produce white latex, ticking down. Native Indians called this latex "tree tears." They condensed the latex into a ball, sang and danced in a circle, and passed it around. The ball bounces high when it hits the ground. This is their most enjoyable game. At that time, the Indians played with solid rubber balls made of raw rubber. Although natural rubber is elastic, its macromolecular chains are like a lot of single springs, piled together, the elasticity is not very large, and these springs are easy to open and separate, so the rubber will break, there is no toughness, and the hair will be a little hot. Sticky and soft.
