Last Saturday, eighty students from our school pay a visit to Liaoning Science and Technology Museum.
The museum, which main task is to spread the knowledge of science and technology, covers area of 15,000 square meters. The moment when we entered the museum, the exhibition caught their attention. In the museum, we saw the latest progresses in science and technology. Moreover, we did an amazed scientific experiment by ourselves. What appealed for us most was the 4D film which made us feel we were in real events.
Though the visiting time was slight short, we gained a lot. It is so an instructive activity that we hope more will be organized in the future.

A company in San Francisco, California, has found a way to turn used plastic bottles into women’s shoes.
Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.
A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company’s co-founder. He explains how ihey turn plastic into soft material for women’s feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers arc then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe arc then attached to the shoe’s outer part, called the sole (鞋底).This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.
Rolhy’s shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. “We’re not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future." When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled material to make other products.
For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.
