- What did people think of Mestral's idea?
- What did NASA think of his idea?
- What products use Velcro today?
- QOD: Mestral thought his idea might be better than what?
Many people thought de Mestral's idea was silly and laughed at him. But de Mestral thought his idea might be a better fastener than the zipper. He patented his idea in 1955 and named it "Velcor." He than started a company to make Velcor. However, it took awhile for people to see how great the fastener was.
In the 1960s, NASA began to use a lot of Velcor. They used it as a fastener on space suits. The space agency's use of the fastener led to its use in many other area of life. Soon shoe companies began to use it on children's shoes. Companies that made ski clothes also saw its usefulness. Today Velcro is widely used on everything from children's toys to blood pressure cuff.
Velcro has had some unexpected uses, too. During the first ever artificial heart surgery, Velcro was used to hold the human heart together!
