This is an innovative use of something outdated and slightly crapp-ola (a lolly machine) transformed into something clever and randomly good (garden bombs).
I saw this on Springwise. They explain the concept best:
The brainchild of Los Angeles-based Common Studio, Greenaid aims to facilitate what it calls “guerrilla gardening” in the many forgotten grey spaces of the urban world, including sidewalk cracks, vacant lots and parking medians. It has reclaimed old, quarter-operated candy machines and converted them for use selling seed bombs—mixtures of clay, compost and seeds that can be thrown anonymously into derelict urban sites.
