As all we know, a straw is disposable and throwaway. The reason that it not reuseable is that the hole is too small to clean. As a result, it will be a major cause of pollution. To reduce the environmental contamination, I would like to recommend “RE - STRAW”. By using this invention, we are able to cut down the pollution because it can be cleaned, then reused. In addition, the RE - STRAW can be unrolled so that it can be used hygienically.
