The water hyacinth grows without bounds in Lake Victoria, Kenya. As an invasive plant with an appetite for environmental and economic destruction, the hyacinth has grown so with vigor, that it has even blocked local fishermen from reaching local waters. Unsure of how to remedy the situation, locals turned to a group of visiting students from the Chalmers University of Technology in Sweden. Understanding the potential of the fibers in the hyacinth, the students found a way to turn lemons into lemonade – or in this case, how to turn the the plants into filaments able to create useful sanitary pads called Janis.
