This project was made in class and the basic idea is to clean the streets from the cigarret trashes  whit it u can smoke and keep the trash of your cigarette till u smoke all box and have a right place to trow it off, because many people smoke and just leave the trashes in the street. the dispencer is a small place located on the inside of the box that as u smoke and consume the cigarets it expands leaving space for the cigar trash.
