Rubber clothesline / Clothesline

People have the discomfort of checking if the laundries are dried of not. People have to go out to see those and that might be quite annoying.
Now with this Rubber clothesline, people can check those laundries just by staring at the window.
Because Rubber clothesline helps people know the difference visually between wetness and dryness.

The rationale behind this is:the elasticity of Rubber
When heavy things are hung, they lengthened much ;
When light things are hung, they lengthened less and keep tightened.
