The master of designing velcro was inspired by Xanthium sibiricum. The name Velcro comes from the fact that both sides of it are made of nylon, one side is lined with small hooks, and the other side is densely wrapped with small coils. When the two sides stick together, the small hook hooks the small coil to make them stick together, so it is named Velcro. Velcro was invented by Swiss inventor George. He likes to take his dog for a walk in the Woods. Once, when he came back from a walk in the Woods with his dog, he suddenly found that the dog's body and trousers were covered with xanthium. It takes some effort to get rid of these xanthium. When he looked at it with a magnifying glass, he found some small thorns in Xanthium sibiricum. These small thorns will stick to the furry pants and will stick tightly. No matter how you throw it, you can't throw it away unless you pull it out by hand. George invented velcro by using the principle of Xanthium sibiricum.
