Admire the planets moving. Follow a ray of light on its journey through the stars. See a black hole up close. Discover gravitational waves. Understanding the deeper nature of space and time. All this can be done in the classroom and at home, with only a rubber sheet and some marbles! 
This is the aim of the open access eBook “Sperimentare la gravità con il telo elastico: linee guida e trucchi – Experience gravity with the rubber sheet: guidelines and tricks” [1] [2] developed by Adriana Postiglione and Ilaria De Angelis of the Department of Mathematics and Physics of the Roma Tre University. Inside the book, the instruction to build a DIY low-cost kit and eight educational cards guide the user step by step in discovering gravity, the force that dominates our Universe. During this talk we will present the project, from the first ideas and attempts to the final realization, including the successful usage experiences during outreach activities and school projects [3]. If possible, a live demonstration of the usage of the kit will be also provided.
