Designing an opener of a water-gel container for people with multiple sclerosis. People with multiple sclerosis have difficulty to open water-gel container by themselves. The design aims to help them open it in the most simple and effective way. The concept arose from a workshop: then, we made a concept water-gel container opener in cooperation with Assciazione Italiana Sclerosi Multipla; now, we want to make the opener more effective and open different size containers.
