Are paper cups really made of paper?
The secret of a paper cup…
Warning! Only under adult supervision.
- drain cleaner;
- glass cup;
- paper cup;
- plastic stick.
The sodium hydroxide in the drain cleaner destroys the paper’s structure, making it easy to clean away. This reveals the plastic film under it, which prevents the paper from getting wet and the beverage from leaking. The film is made of polyethylene, so this "paper" cup can not be recycled with regular paper. It requires separate collection and special processing.
