The winning contribution, developed by five students at ENSAM University in Paris, is a waterproof dispenser with a choice of two different attachment solutions: a suction pad or a hook. The dispenser is made from a soft, lightweight and impact-resistant material that keeps the toilet paper free from humidity through the use of silica gel.

“Thinking about the extreme environment on board – and aside from the challenge of developing an easy-to-use dispenser that is completely waterproof – we thought portability would be an important feature,” said Inés Ballano Vicente from the winning team. “That’s why we developed the two different attachment solutions.”
